Novon, A Journal for Botanical Nomenclature from the Missouri Botanical Garden
The mission of the Missouri Botanical Garden is to discover and share knowledge about plants and their environment, in order to preserve and enrich life.
Novon publishes short articles whose primary purpose is the establishment of nomencla¬ ture in vascular plants and bryophytes. All articles are peer-reviewed by qualified, indepen¬ dent reviewers.
Manuscripts must fully state and justify the reasons for proposing nova. These may include detailed comparisons with similar taxa, short keys to similar taxa, illustrations to similar taxa, and mechanical nomenclature reasons, among others. Manuscripts whose primary purpose is other than establishment of new nomenclature, which usually are longer manuscripts, cannot be accepted for review. These include reviews, revisions, monographs, or other papers that incidentally include nova.
Manuscripts must follow the guidelines in the Checklist for Authors. The Checklist may be downloaded from the Garden’s web site, www.mbgpress.org, or authors may contact the man¬ aging editor to request a copy.
Novon will not knowingly accept manuscripts that have been simultaneously submitted to other journals for consideration or previously published in some form elsewhere.

Burmese amber has yielded a wealth of arthropod and plant remains (Poinar et al., 2005), including some very interesting angiosperm fossils. These include flowers with affinities to the family Monimia- ceae (Poinar & Chambers, 2005), Cornaceae (Poinar et al., 2007b), and the rosid clade of eudicots (Poinar et al., 2008), as well as two early bambusoid grasses (Poinar, 2004). In the present paper, we describe an
Hukawng Valley in Burma (Myanmar).
Materials and Methods
The amber was derived from a mine first excavated
Maingkhwan in the state of Kachin (26°20'N, 96°36'E) in Burma (Myanmar). This new amber site,
known as the Noije Bum 2001 Summit Site, was assigned to the Upper Albian of the Early Cretaceous on the basis of paleontological evidence (Cruickshank & Ko, 2003), placing the age at 97 to 110 million years ago (Ma). Nuclear magnetic resonance (NMR)
amber samples from the Noije Bum 2001 Summit site indicate an araucarian (possibly Agathis Salisb.) tree source for the amber (Poinar et al., 2007b).

Although most of the stamens are broken, one stamen retains its anther (Fig. 1A, left insert), showing that the flower was bisexual in organization. The disc is conspicuous, darkly stained, and bears three short, curved, acute styles. The disc has an irregular margin and is trilobed (Fig. 3A), each
secretory, the dark coloration may be an artifact from chemical alteration of nectar on its surface. The

similarity to certain anthers of Cunoniaceae, as
appears basal, would instead be dorsal by similar analogy to these comparable anthers. A notable feature of the ovary is that it has 10 prominent
sepals and five alternating with the sepals (Fig. IB). On one side of the ovary we noted that each rib has a dark-staining triangular pad of tissue at its distal end (Fig. 1C). This is a regular feature, not an artifact, on all the ribs in this field of view. In other views, this dark tissue appears to be frayed or macerated. We

morphology does not present any obvious apomor- phies. Apetaly occurs in at least 10 modem families of rosids (Endress & Matthews, 2006: 231, fig. 11), and
plesiomorphic in the entire clade. The presence of ribs on inferior ovaries is also common in extant flowers. Their number is often twice the number of
traces (median and synlateral) of the sepals (Endress, 2008: fig. 13). In several salient features, the floral morphology of fTropidogyne resembles members of
genus Ceratopetalum Sm. Our discussion is based on the descriptions, anatomical studies, and excellent SEM illustrations of this genus from the works of Engler (1930), Hoogland (1960), Dickison (1975, 1989), Hufford and Dickison (1992), Matthews et al. (2001), Bradford and Bames (2001), Hopkins and Hoogland (2002), Rozefelds and Barnes (2002), Matthews and Endress (2002), and Bradford et al. (2004).

(Barnes & Hill, 1999). Ceratopetalum sepals are
of the dry indehiscent fruits (pseudosamaras, cf. Hopkins & Hoogland, 2002: 76), hence they are well preserved as fossils. Tropidogyne is apetalous, as are eight of the nine species of Ceratopetalum (Rozefelds & Barnes, 2002). Ceratopetalum gummiferum has five wedge-shaped, 3-toothed petals (Engler, 1930; Mat¬ thews et al., 2001: 445, fig. 8). The related genus Schizomeria D. Don (Cunoniaceae) differs from the

The androecium of both f Tropidogyne and Cerato¬ petalum is diplostemonous, with subulate filaments and small, bithecal anthers (Dickison, 1989: 55, fig. 4.2 F; Rozefelds & Barnes, 2002: 658, fig. 5). The

of, e.g., C. tetrapterum Mattf. (Rozefelds & Barnes, 2002: 659, fig. 6J and other anthers there illustrated). Our interpretation of introrse dehiscence for the fossil similarity to the modern genus, m of Ceratopetalum is consistently bicarpellate (Hopkins & Hoogland, 2002; Bradford et al., 2004), but the tricarpellate condition of f Tropid-
& Hoogland, 2002) as well as elsewhere in Cunonia¬ ceae (Bradford et al., 2004). In both f Tropidogyne and Ceratopetalum the styles arise separately from a
short, curved-divergent, and acute (Rozefelds & Barnes, 2002: 658, fig. 5). In both, the stigmas are scarcely defined; Matthews et al. (2001: 448, fig. 34) illustrate the stigma of C. gummiferum as a papillate region at the very tip of the style. The ovary of Ceratopetalum is described as half-inferior (Hoogland, 1960; Dickison, 1975: 441, fig. 21; Bradford & Barnes, 2001; Bradford et al., 2004), but this is developmentally variable in the genus. For example, in the serial cross sections illustrated by Matthews et al. (2001: 442, fig. 4) for a flower bud of C. gummiferum, the locules and ovules in the ovary are

Abstract . The name Parodia leninghausii (F. Haage) F. H. Brandt (Cactaceae) is in common use for a widespread and easily grown plant, but no valid combination has ever been published.

irally still encountered under the name . Berger, there is substantial agreement (Anderson, 2001, 2005; Hunt et al., 2006) now that Notocactus (K. Schum.) Fric is a

history of the nomenclature and taxonomy of the taxon, presented here, elucidates the reasons for this
interpretation of the original sources for basionym and combinations. This evaluation also shows that the customary spelling “ leninghausii ” is erroneous and must be corrected to “ lenninghausii .”
Outline of the Nomenclatural History
Pilocereus leninghausii (note spelling) (nom. inval., International Code of Botanical Nomenclature [ICBN], Art. 32. Id; nom. incorr., Art. 11.4; McNeill et al., 2006) by Schumann (1895: 147), ascribing the name to F. Haage. In the same paragraph, Schumann
Otto and uses the provisional name E. leninghausii
(note spelling) (nom. inval., Art. 34.1b; McNeill et Schumann” was again used (Schumann in Hirscht,
Cactus Society, but without descriptive matter.
In the following year, the name Pilocereus len¬ ninghausii (note spelling) “Haage jr.” was published
accompanied by an illustration, in the German edition of the 1896 catalogue of the world-renowned nursery of Friedrich Adolph Haage Jr., Erfurt, Germany (Haage, 1896: 14). This is the first valid publication
lenninghausii F. Haage, even though it is incorrect under Article 11.4 (McNeill et al., 2006) since Pilocereus K. Schum. (Schumann, 1894) (established
[Lemaire, 1839]) is illegitimate (Art. 53.1) versus Pilocereus Lem. (Lemaire, 1839), which is itself illegitimate (Art. 52.1) versus Cephalocereus Pfeiff. (Pfeiffer, 1838) (Index Nominorum Genericorum, ac¬ cessed May 2008 at <http://botany.si.edu/ing/ingForm. cfm>).
In 1897, the name Pilocereus lenninghausii (note spelling) “Haage jr.” also appears with a short but unambiguously acceptable diagnosis, and with the same illustration as 1896, in the English edition of a Haage catalogue (Haage, 1897a: 25). The name (with the same spelling) and illustration (but not the description) also appear in the German edition of this catalogue (Haage, 1897b).
In 1898, the name Echinocactus leninghausii (note spelling) K. Schum. is used by Schumann (1897- 1898: 382-383), referring to the 1895 note published by Schumann (Schumann, 1895), and an (unspecified) catalogue of “Ferd. Haage sen.” Echinocactus lening¬ hausii could either be interpreted as the name of a new taxon (the name is attributed to K. Schumann,
description), or (under Art. 33.2; McNeill et al., 2006) as combination for Pilocereus leninghausii F. Haage

references cited after the German description. On the basis of these references, we can safely conclude that
citation is, therefore, Echinocactus lenninghausii (F. Haage) K. Schum. (as “ leninghausii ”), Gesamtbeschr. Kakt., 382-383, 1898 (basionym: Pilocereus len¬ ninghausii F. Haage, 1896). IPNI (accessed April 2009 at <http://www.ipni.org/ipni/plantnamesearch- page.do>) incorrectly attributes the name to Schu¬ mann (1900: 134).
Subsequently, combinations were published as Malacocarpus lenninghausii (F. Haage) Britton &
Notocactus lenninghausii (F. Haage) A. Berger (as Uleninghausir ) (Berger, 1929), Eriocephala lenning¬ hausii (F. Haage) Heinrich (Heinrich, 1940) (combi¬ nation attributed to Backeberg, but Art. 46.4 applies; McNeill et al., 2006), and Eriocactus lenninghausii (F. Haage) Backeb. (Backeberg, 1942) (nom. incorr., Art. 11.4, because Eriocactus Backeb. is an unnecessary illegitimate nomen novum [Art. 52.1] for Eriocephala Backeb.).
Finally, Brandt (1982: 61) published the combina¬ tion Parodia lenninghausii “(F. Hge.) Brandt comb, nov.” (as “ leninghausii ”), citing the 1895 nomen nudum “ Pilocereus leninghausii F. Haage Cat. K.
This is obviously not the correct reference to the basionym name, and the combination at first glance can be dismissed under ICBN Article 33.4 (McNeill et al., 2006). Article 33.5 does not apply, but the provisions of Article 33.7 need to be evaluated carefully: 33.7(a) does not apply, as the name was validly published later than the reference given, and
apply; 33.7(d) is more complicated, as Brandt also cites “ Notocactus leninghausii (F. Hge.) Buxb., Krainz, Die Kakteen 1.1.1967.” This relates to the

Krainz (1968) reproduces a Latin diagnosis copied from Schumann (1897-1898), and since the errone¬ ous citation can be treated as a correctable error, Article 33.7(d) seems to be applicable.

found in Schelle (1907: 178). The drawing (wood- cut) leaves nothing to be desired as to clarity, and no epitype is necessary to fix the application of the name (Fig. 1).

Abstract. Zornia grandiflora Fort.-Perez & A. M. G. Azevedo (Leguminosae, Papilionoideae), a new species from Bahia and Pernambuco states in northeastern Brazil, is described and illustrated. The
Mohlenbr. of subgenus Zornia J. F. Gmel. Zornia grandiflora is similar to Z. sericea Moric., sharing erect stems and ovate to elliptic bracteoles. It can be
within Zornia sect. Anisophylla by the large standard (13-17 mm long).
Resumo. Zornia grandiflora Fort.-Perez & A. M. G. Azevedo (Leguminosae, Papilionoideae), uma nova especie do nordeste do Brasil (estados da Bahia e Pernambuco), e descrita e ilustrada. Esta nova especie pertence a segao Anisophylla Mohlenbr. do subgenero
idades com Z. sericea Moric., compartilhando os ramos eretos e as bracteolas ovais a elipticas; e pode ser separada desta e das outras especies de Zornia
darte (13-17 mm comprimento).
The genus Zornia J. F. Gmel. (Leguminosae, Papilionoideae) comprises about 75 to 80 species from the tropics and subtropics (Mohlenbrock, 1961; Rudd, 1981; Klitgaard & Lavin, 2005), and ca. 36 species are estimated from Brazil. According to a molecular study carried out by Lavin et al. (2001), the genus has been included in the Adesmia DC. clade of tribe Dalbergieae s.l.
Species of Zornia share several morphological characters: each flower is surrounded by a pair of peltate bracteoles similar to the stipules, the leaves are 2- or 4-foliolate, and the stems frequently are diffusely branched and woody at the base. The size and form of the bracteoles (bracts) are important

According to Tucker (1987), the prophylls are opposite and paired in most dicotyledons and are the first products of the axillary vegetative apex. In Zornia, as well as other species of dalbergioid genera, each flower is subtended by a pair of bracteoles, with the flowers of Zornia sessile instead of pedicellate as in Ormocarpum P.

Taxonomy of Basicladia (Cladophorales, Chlorophyta) with Two New Combinations
David J. Garbary
Department of Biology, St. Francis Xavier University, Antigonish, Nova Scotia, Canada, B2G 2W5. dgarbary@gmail.com
Abstract. The green algal genus Basicladia W. E. Hoffman & Tilden suggested for synonymy in
as a genus based on the distinct basal system and the primarily epizoic habit associated with freshwater turtles. Previously assigned to Cladophora sect. Basicladia (W. E. Hoffmann & Tilden) C. Hoek, C.
Ueda) C. Hoek (type: Japan) transfer to Basicladia, based on morphology and molecular evidence. The two new combinations B. kosterae (C. Hoek) Garbary and B. okamurae (S. Ueda) Garbary bring the number of species in Basicladia to seven.
Key words: Basicladia, Cladophora, Cladophor¬ ales, turtle algae.
The cladophoroid genus Basicladia W. E. Hoff¬ mann & Tilden (Hoffmann & Tilden, 1930) was initially described for two species of epizoic algae on
added, all of which were either epizoic on turtles or occurred on a freshwater snail. Five species have now been assigned to the genus: B. crassa W. E. Hoffmann & Tilden (generitype), B. chelonum (Collins) W. E. Hoffmann & Tilden, B. ramulosa Ducker (Ducker, 1958), B. sinensis (N. L. Gardner) G. M. Sm. (Smith, 1950), and B. vivipara Normandin & Taft (Normandin & Taft, 1959). The genus Basicladia is widely distributed in freshwater habitats where turtles are present (e.g., Yoneda, 1952; Ducker, 1958; Prasad &
2007).
In his monograph of European Cladophora Kiitz., van den Hoek (1963) considered Basicladia as a
sectional status within the genus. However, he incorrectly designated B. chelonum as the type, and none of the five existing species of Basicladia were formally transferred into Cladophora. A new species
and Chaetomorpha okamurae S. Ueda was formally transferred to Cladophora as C. okamurae (S. Ueda) C. Hoek. Van den Hoek (1963) left us with several taxonomic and nomenclatural issues. First, the type of
Cladophora sect. Basicladia was not assigned to Cladophora. Furthermore, if Basicladia was distinct
and C. okamurae continue to be considered as members of Cladophora, or should they be recognized as species of Basicladia ? These issues can now be resolved.
Molecular evidence shows Cladophora to be extremely diverse, forming an ancient assemblage from which several green algal lineages are derived. Even within a limited clade (e.g., the Cladophora
there were six distinct ITS sequence types (Bakker et al., 1995). More recent molecular studies involving a diverse assemblage of Cladophorales and Siphonocla- dales showed that various siphonoclad lineages were
species (Leliaert et al., 2003, 2007). Thus, if nu¬ merous traditional genera of siphonoclads belonging to multiple families continue to be recognized, Cladophora can no longer be considered a natural
A similar conclusion regarding the monophyly of Cladophora was inherent in the results of Yoshii et al. (2004) and Yoshii (2006), in which a wide range of species of Cladophorales was examined for pigment composition and 18S ribosomal DNA (rDNA) se¬ quences. Cladophora species were sister to species in other genera of Cladophorales and Siphonocladales, e.g., Chaetomorpha Kiitz., Cladophoropsis Bprgesen, Valonia C. Agardh, and Pithophora Wittr. Hence, the cladophoroid morphology is plesiomorphic or possibly
needs to be broken down into monophyletic units that can be recognized at generic level. Some of these units may already have been characterized in the various sections of Cladophora (van den Hoek, 1963).
by Yoshii et al. (2004) is Basicladia. While virtually all authors continue to recognize Basicladia (e.g., Ernst & Norris, 1978; Colt et al., 1995; John, 2003; Garbary et al., 2007), AlgaeBase follows van den Hoek (1963) and states that Basicladia is a synonym of Cladophora (Guiry & Guiry, 2007).

New Combinations in Basicladia (Cladophorales)

species. The association with turtles is diagnostic, even if not all species occur on turtles, and some species have been found on other substrata (Proctor, 1958; Normandin & Taft, 1959; van den Hoek, 1963). It is this heterotrichous basal layer that provides the
filaments can be produced from a longer-lived basal
When van den Hoek (1963) reduced Basicladia to a section of Cladophora in his monograph of European Cladophora, none of the five species previously assigned to Basicladia were formally transferred. Furthermore, only two species were included in the section — the new species C. kosterae and C. okamurae (the latter transferred from Chaetomorpha ; see Ueda, 1932). Neither species was found on turtles. Belusz and Reed (1969) later reported C. kosterae from North America as epizoic algae on turtles. The association of C. kosterae with Basicladia was later confirmed when Yoshii et al. (2004) used sequence data from type material of C. kosterae to show a sister group relationship between C. kosterae and two isolates of unidentified Basicladia from the United States in the UTEX culture collection (<http://www.utex.org/>).
Since Basicladia is a viable genus independent of Cladophora, and C. kosterae is part of the Basicladia clade, C. kosterae is hereby transferred to Basicladia. The morphology of C. okamurae is also definitive for 3 also transferred.

During taxonomic studies of the genus Baccharis in Brazil, lectotypification of three names published by Malagarriga (authored as Irmao Teodoro Luis*; Malagarriga, 1949, 1954) and the validation of one published by Barroso (1976) became necessary, mainly because holotypes were not clearly indicated at the time of publication. For the current designation of type, the best preserved and most representative specimens, according to the protologues, were chosen from the original material.

Abstract. Rhodiola wenchuanensis Tao Li & Hao Zhang (Crassulaceae) is described and illustrated from Wenchuan County, in western Sichuan Province, China. The new species is related to R. discolor (Franch.) S. H. Fu, but differs in having smaller plants with densely puberulent stems and pedicels and sessile leaves. It is characterized by its obviously dentate leaf margins; a petal to stamen length ratio less than or equal to 1; crimson sepals, petals, and ripe fruits; and a carpel that is not developed in the staminate flower. The new species is assigned to
Rhodiola L. on the basis of its dioecy and its flowers in terminal corymbs with four or five erect, shortly oblong carpels with the apex not revolute and the base
Rhodiola L. (Crassulaceae) consists of 96 species that are distributed mainly in alpine regions through-
Tibetan Plateau and to the European Alps. Species in the genus are herbaceous perennials of alpine meadows, forests, and mountain glacier habitats. There are 73 species, two subspecies, and seven varieties in China (Fu, 1984). Rhodiola plants are mainly distributed in southwestern and northwestern China, with most taxa (32 species and two varieties) located in Tibet, and with 22 species in Sichuan Province (Wu, 1985; Ji et al., 2007). During fieldwork in 2006 and 2007 as part of the floristic Rhodiola on the Qinghai-Tibetan Plateau i Sichuan Province, three populations of an taxon were collected first on Balang Wenchuan County and later on Jiajin Mountain in

Abstract. A lectotype is designated for Actinidia latifolia (Gardner & Champ.) Merr. var. deliciosa A. Chev. (Actinidiaceae), selecting the second plate from the Chevalier protologue. Actinidia latifolia var. deliciosa is the basionym for the well-known kiwifruit A. deliciosa (A. Chev.) C. F. Liang & A. R. Ferguson.

be the same taxon as A. chinensis var. deliciosa (Liang & Ferguson, 1984, 1986; Ferguson, 1990). Gui (1981) was the first to point out that the morphological
autonymic variety justified specific separation. Al-
deliciosa should not be given specific status, Liang and Ferguson (1984, 1986) did raise it to the rank of species in the new combination A. deliciosa (A. Chev.) C. F. Liang & A. R. Ferguson. From then on, it has been hotly debated whether the two taxa are two

The two taxa are very similar to each other. The main differences between Actinidia chinensis var. chinensis and A. chinensis var. deliciosa are that the former has young branchlets and petioles that are white pubescent to roughly tomentose, glabrous to glabrate when mature, and fruits that are densely tomentose, but soon glabrous. In variety deliciosa, the young branchlets and petioles are brownish strigose, with the hairs not easily lost, and the fruits are densely hispid, more or less hispid when mature (J. Q. Li et al., 2007). Actinidia chinensis var. deliciosa : distributed in western mainland China, whereas
chinensis var. chinensis is found further to the east (Liang, 1975; Ferguson, 1990; J. Q. Li et al., 2007). The plants are of great economic importance, because their fruits, well-known as kiwifruit, are popular all over the world. More than 120,000 ha. of orchard are planted with the two taxa, with an annual production exceeding 1.35 million tons of fresh fruit (Ferguson & Huang, 2007).
The taxonomy of Actinidia chinensis var. chinensis and A. chinensis var. deliciosa needs further revision based on extensive population sampling across their entire geographic range,

We suspected that perhaps Cheva¬ lier had preserved a specimen in the Museum National d’Histoire Naturelle (P), since the plant was cultivated in the Jardin des Plantes in Paris. Dr. Joel Jeremie kindly helped in searching through the specimens at P identified as A. latifolia var. deliciosa, in particular for specimens annotated by Auguste Chevalier, but no type specimen was ever discovered. We therefore think that it is necessary to designate a
latifolia var. deliciosa (Chevalier, 1940). The first one shows the whole liana growing against a wall in the Jardin des Plantes. The second plate (Chevalier, 1940: 15, planche II; our Fig. 1) shows a fruiting branch alongside detached fruits (one bisected longitudinal-

fruiting branch with one to two fruits per infructes- cence; and fruits that are ellipsoid or ovoid and hispid, with reflexed persistent sepals and long pedicels. In contrast, the infructescence of A. latifolia has many glabrous fruits when mature. According to

Abstract. Two new tropical species in Eleocharis subgen. Limnochloa (P. Beauv. ex T. Lestib.) Torr. (Cyperaceae) are described and their relationships with presumably allied species are discussed. Eleo¬ charis hooperiana D. J. Rosen from Sierra Leone in West Tropical Africa differs from the morphologically similar and presumably close taxonomic ally E. nupeensis Hutch, in a combination of coarser culms, longer and more coarsely spinulose perianth bristles, and larger fruits. Eleocharis tenuiculmis D. J. Rosen from the Brazilian state of Mato Grosso differs from the similar slender-culmed species E. elongata Chapm. in a combination of narrower culms, longer perianth bristles, and generally larger, biconvex fruits. Resumen. Se describen dos nuevas especies tropi- cales de Eleocharis subgen. Limnochloa (P. Beauv. ex T. Lestib.) Torr.

Eleocharis R. Br. (Cyperaceae) is a cosmopolitan genus of over 200 species with a center of diversity in the Neotropics (Gonzalez-Elizondo & Tena-Flores, 2000). Eleocharis subgen. Limnochloa (P. Beauv. ex T. Lestib.) Torr. is distinguished from other Eleocharis by a combination of cartilaginous, obscurely keeled,
usually as thick as the cylindrical spikelet; and biconvex (rarely trigonous) achenes usually sculp¬
tured with large, polygonal cells (Gonzalez-Elizondo & Peterson, 1997). A recent resurgence of systematic study in subgenus Limnochloa has resulted in the description of several new species, particularly from the New World Tropics (Gonzalez-Elizondo & Rez- nicek, 1996; Roalson, 1999; Trevisan & Boldrini, 2006; Rosen et al., 2007; Rosen & Hatch, 2007).

shrubs to large trees and some woody climbers found in both the New and Old World tropics.
Morinda and Appunia are distinguished primarily by the arrangement of their flowers, with those of each inflorescence all fused at the ovary portion and
the flowers free with each producing a free drupe in Appunia. Additionally, these genera have sometimes been separated by their stigmas, two and linear in
mark (1972: 384-385) reviewed these genera and noted that ps :d stigmas are also found in several species with free fruits (e.g., A. triphylla Ducke) and
only in their basal half’ (e.g., M. hoffmannioides Standi.), which he considered to be a condition intermediate between the two genera. Accordingly,
separate Appunia and Morinda were continuously variable and not consistently correlated, and he formally synonymized these genera. This conclusion
Taylor & Pool, 1993; Taylor, 1999; Boom & Delprete, 2002; Taylor et al., 2004). However, this synonymization has not been accepted by some (e.g., Taylor, 2001; Lorence considered the free versu versus multiple fruits to be clear consistent differ-
intermediate in this feature. The individual fruits of M. hoffmannioides, described as “partially fused” or “partially coherent” by Steyermark, appear in our
fall (i.e., disperse) as a single unit, although presumably these fruits are eaten by birds and sometimes individual pieces corresponding to the
group. The variation in stigma form has not been carefully re-surveyed, but as shown by Steyermark
Spermacoce L.), and therefore does not necessarily seem taxonomically informative for either synonymi¬ zation or separation of these genera.

cence “extra-axillary” (1934: 276). This arrangement is produced when the terminal inflorescence is subtended by two nodes that are not separated by an intemode, with a pair of leaves developing from one node and only one leaf developing from the other, and often with one axillary bud developing to produce a
lateral displacement of the inflorescence. A similar arrangement is found in several other genera of Rubiaceae (e.g., Duperrea Pierre ex Pit., Brachytome

Abstract. Two novelties in the genus Senecio L.
and illustrated: a new species, S. breviramulus Tortosa & Adr. Bartoli belonging to series Xerosenecio (Cabrera) Cabrera & S. E. Freire, and the new variety pinohachense Tortosa & Adr. Bartoli for S. volckman-
subser. Candidi (Cabrera) Cabrera & S. E. Freire. The new species is allied to S. covasii Cabrera and S. pumilus Tortosa & Adr. Bartoli, from which it differs by the smaller, narrowly elliptic leaves and narrower heads with fewer flowers. The new variety of S. volckmannii differs from the typical variety by the presence of female ray florets and the pedunculate

Asteraceae, IUCN Red
The genus Sei species worldwide, with the highest diversity in desert regions of southern South
America, tropical South Africa, and central and eastern Asia (Bartoli et al., 2004).
In southern South America, the genus is represent¬ ed by ca. 643 species, of which 280 were recognized by Cabrera (1949) in Chile; 90 in Brazil, Uruguay, and Paraguay (Cabrera, 1957); and 114 in Bolivia (Cabrera, 1985). In Argentina, according to Cabrera et al. (1999) Senecio is represented by 266 native species, arranged in three sections and 16 series. Since the publication of that paper for Argentinean species, several authors have made research contri¬ butions. In 2001, Tombesi described S. calingastensis Tombesi, belonging to series Corymbosi (Cabrera) Cabrera subser. Brasilienses Cabrera & S. E. Freire (Tombesi, 2001). Later, Long (2002) included S. quequensis Cabrera of series Xerosenecio (Cabrera) Cabrera & S. E. Freire subser. Filaginoidei (Cabrera) Cabrera & S. E. Freire in the synonymy of S. bergii Hieron. Subsequently, Bartoli et al. (2004) described S. nemiae Adr. Bartoli, Tortosa & S. E. Freire of series Corymbosi subser. Adenotrichi (Lindl.) Adr. Bartoli, Tortosa & S. E. Freire. Afterward, Tortosa and Bartoli (2005) founded two new entities, S. fragrantissimus Tortosa & Adr. Bartoli and S. pumilus Tortosa & Adr. Bartoli, both species belonging to series Xerosenecio subser. Filaginoidei. Troiani and Steibel (2006) described a new species from Patagonia, S. chipau- quilensis Troiani & Steibel, from series Xerosenecio subser. Microcephali (Cabrera) Cabrera & S. E. Freire, and Tortosa and Bartoli included S. rosmarinus Phil, and S. spegazzinii Cabrera as synonyms of S. volckmannii Phil., which belongs to series Sujfruticosi Cabrera subser. Candidi (Cabrera) Cabrera & S. E. Freire. Tortosa and Bartoli later resurrected S. floccidus Hombr. & Jacquinot of series Xerosenecio subser. Filaginoidei and concluded that S. patagoni- cus Hook. & Arn. var. andersonii (Hook, f.) Cabrera is

a synonym of S. arnottii Hook. f. (Tortosa & Bartoli, 2007). Recently, Tortosa and Bartoli (2008) have redefined S. filaginoides DC. and resurrected three species, S. caricifolius Hook. & Arn., S. leuciscus Phil., and S. quenselii Skottsb., all belonging to series Xerosenecio subser. Filaginoidei.
During the revision of Senecio sect. Senecio (Aster¬ aceae) in Patagonia, we found a new species of series Xerosenecio subser. Microcephali and a new variety of S. volckmannii, which belongs to series Suffruticosi subser. Candidi (Cabrera et al., 1999). Both series are found in southern South America; series Xerosenecio,
capitula that are grouped in terminal corymbs, while in series Sujfruticosi, with 143 species, the capitula are solitary or occasionally in groups of two to three (to five) and are discoid or with marginal filiform flowers. The
radiate or discoid capitula may be variable within a single species. The overlapping of these characters
the ai t il South American species of Senecio. Although useful for a genus with such a large number of species, this artificial classification does not reflect the phylo-
strated by Tortosa and Bartoli (2006), who transferred to the synonymy ol S. volckmannii two species with solitary heads, S. rosmarinus and S. spegazzinii, which were

Distribution and habitat. Senecio breviramulus has been found in the mountains in the north of Neuquen Province, Argentina, at elevations of 1700—1800 m. This species grows on dry sandy soil with rocky outcrops in rather scattered populations and is associated with species of Festuca L., Stipa L., Poa L., Mulinum Pers., and Chuquiraga Juss.
IUCN Red List category. Due to the reduced population size, very restricted area of occupancy, and lack of data on changes in population size, this species should be considered Critically Endangered (CR) according to IUCN Red list criteria (IUCN, 2001).
Etymology. The specific epithet breviramulus is stems of the new species.

with scattered leaves. The new species can be distinguished from them by its smaller, narrowly elliptic leaves and the smaller, narrow heads with fewer florets (12 to 14 vs. 20 or more in both affined species). The new species is placed in series Xerosenecio because of the shape and size of the involucre, which we regard as having special taxonomic value to redefine the series (Tortosa & Bartoli, unpublished).

Abstract. Following molecular phylogenetic e
biphyletic, with supporting evidence from seve: morphological traits, the species D. alternifolius transferred to the genus Erigeron L. as E. alternifolius (Lawesson & Adsersen) N. Andrus & Tye.
Key words: Darwiniothamnus, Ecuador, Erigeron, Galapagos.
The genus Darwiniothamnus Harling (Asteraceae, Astereae) was erected in 1962 for two Galapagos endemic species, which Hooker (1847) originally assigned to Erigeron L. To the two original species, D. lancifolius (Hook, f.) Harling and D. tenuifolius (Hook, f.) Harling, a third was added with the discovery of D. alternifolius Lawesson & Adsersen (Lawesson & Adsersen, 1987). Two different growth forms were encompassed within the genus as so defined. Darwin-
shrubs that usually grow to 1-2 m in height and occasionally reach 3.5 m, have leaves condensed in terminal whorls with internodes much shorter than half the length of the leaves, a condensed corymbiform synflorescence more or less enclosed within the terminal leaves, and 3- to 6-nerved achenes (Harling, 1962; Lawesson & Adsersen, 1987). In contrast, D. alternifolius is a perennial herbaceous plant, woody only at the base, reaching up to 50 cm in height and having alternate leaves not condensed in terminal whorls, with internodes at least half the length of the leaves, a cymiform synflorescence that exceeds the terminal leaves, and with all achenes 2 -nerved (Law¬ esson & Adsersen, 1987; pers. obs.). The three species were nevertheless considered to belong to a single genus because they possess many ray florets, imbricate phyllaria of unequal length, slightly dimorphic

Darwiniothamnus, using nucleotide sequences of the internal transcribed spacers of nuclear ribosomal DNA (Andrus et al., 2009), indicates that Darwin¬ iothamnus is biphyletic, with both northern and southern origins. Darwiniothamnus lancifolius and D. tenuifolius form a monophyletic assemblage that shares a recent common ancestor with the Cuban
nests with a number of Greater Antillean endemics grouped as Erigeron sect. Microcephalum Nesom (Nesom, 2008). Darwiniothamnus alternifolius shares recent ancestry with Chilean species of Erigeron, forming a clade with E. luxurious and E. fasciculatus (as suggested by Harling [1962] for the other two Darwiniothamnus species, but to which they are not closely related [Andrus et al., 2009]), and nested with Erigeron sect.

Abstract. Erigeron latifolius Hao Zhang & Z. F. Zhang (Asteraceae, Astereae), a new species of Erigeron L. from Sichuan, China, is described and illustrated. It is similar to E. multiradiatus (Lindl. ex DC.) Benth. ex C. B. Clark, but can be distinguished by features of the flowers and leaves. The capitula are small (1.2-2.5 cm); the anthers do not protrude beyond the corolla; the midcauline leaves are large (8-15 X 1-2.5 cm) and lanceolate to oblong- lanceolate; and the distal leaves are lanceolate, dense, and not much reduced, but smaller (2—5 X 0.5-1 cm). The new species is endemic to China and is identified as Endangered (EN), according to IUCN Red List criteria.

northern American and Eurasian continents. In China, 35 species are recorded and principally occur on the Qinghai-Tibetan Plateau, which is the center of diversity for Erigeron. The species are divided into two subgenera including subgenus Erigeron and subgenus Trimorpha (Cass.) Popov (Ling & Chen, 1973, 1985).
Since the 1980s, there have been few reports on the taxonomy of Erigeron in China. A new variety of E. breviscapus (Vaniot) Hand.-Mazz. was described from Yunnan in 2003 as variety leucanthus X. D. Dong & Ji H. Li (Dong & Li, 2003). In our previous study, the morphology of several Erigeron species from the European Alps was investigated (Walter & Zhang, 1991), as well as the distribution and chemical constituents of Erigeron species from the Qinghai- Tibetan Plateau (Zhang et al., 1998; Hu et al., 2001, 2005; Zhang et al., 2003; Zhang & Zhang, 2004).

As defined here, flower length includes the pedicel. Papillae, defined as epidermal projections and considered subsets of trichomes (Metcalfe & Chalk, 1979), occur on the tepals and stamens. Branchlets
and inflorescences are always associated with rhyth¬ mic growth, which can be diagnosed by its periodicity and by the leaves distinctly clustered at the top of the branchlets (Halle et al., 1978).

Abstract. Clidemia fluminensis Baumgratz & D’El Rei Souza (section Staphidium (Naudin) Griseb.,
Rio de Janeiro. Brazil, is described and illustrated. The new taxon occurs in Pogo das Antas Biological
ecosystem. The new species is distinguished mainly by the scandent habit, membranous leaves, terminal inflorescences, and flowers with yellow petals with an obtuse and apiculate apex. It is related to C. conglomerata DC. and C. involucrata DC., sharing the glomeruliform inflorescence, the stamen connec¬ tive not prolonged or appendaged, and the pilose ovary apex.

Abstract. Cyperus absconditicoronatus Bauters, Reynders & Goetgh. and C. unispicatus Bauters, Reynders & Goetgh., two new species of Cyperus L. (Cyperaceae) from Angola and Zambia, are recog¬ nized. Cyperus absconditicoronatus is a tall species (55-100 cm) characterized by a scaled rhizome, a single terminal capitulum, a ciliated spikelet bract, and deciduous spikelets. Cyperus unispicatus can be
from slender rhizomes, a single terminal spike, and short involucral bracts. The taxa are described and
bling species are discussed.
Key words: Africa, Angola, Cyperaceae, Cyperus, IUCN Red List, Zambia.
The genus Cyperus L. s. str. (Cyperaceae) includes 696 accepted species worldwide (Govaerts et al., 2008). Cyperus can be recognized by a usually
lucral bracts, spikelets with several to many fertile and usually distichous glumes, the rachilla of the spikelet either persistent or not, the flowers without a perianth, and a trifid, less often bifid, or rarely nondivided style.
During the examination of some specimens of Cyperus in the Ghent University Herbarium (GENT)
authors, several specimens were encountered that could not be assigned to any known species in the genus (after identification with Kukenthal, 1935- 1936; Chermezon, 1937; Hooper & Napper, 1972; Haines & Lye, 1983). One of the specimens (H. & E. Hess 52/545 ) was incorrectly identified by Mincier (1984) as Mariscus albopilosus C. B. Clarke (accepted name = Cyperus albopilosus (C. B. Clarke) Kiik.). In his master’s thesis on the Cyperaceae from Angola, he mentioned another specimen (H. & E. Hess 52/262 ) as “ Mariscus sp. nov.” (Mincier, 1984: 180). Both specimens clearly belong to the same new species. In the herbarium of the National Botanic Garden of Belgium (BR), a third specimen (M. G. Bingham
7042/2 ) of this taxon was found, incorrectly identified
Mincier (1984: 182) also mentioned the only known specimen (H. & E. Hess 52/34 ) of the second new species, Cyperus unispicatus Bauters, Reynders
new species in Cyperus sect. Bulbocaules (C. B. Clarke) Kiik., which is characterized by a swollen stem base.

Taxithelium is a pantropical genus occurring mainly in Southeast Asia between 30°N and 20°S. The genus is currently under taxonomic revision by this author, and it has been suggested to be monophyletic by the ongoing work by Camara and Shaw (unpublished). It is characterized by the presence in the gametophyte of multiple papillae serially disposed over the lumina of leaf cells (a rare character present only in one other genus :: Radulina W. R. Buck & B. C. Tan). Taxithelium also has a poorly developed alar region, and the sporophytes lack collenchymatous exothecial

Eight new combinations are presented here to allow proper recircumscription of the genus. These taxa all lack pluripapillose leaf cells, which is a diagnostic character for Taxithelium. This observation is ad¬ dressed in more detail in the SEM studies by Camara and Kellogg (2010).

Abstract . Five new combinations in Schoenoplectus (Rchb.) Palla (Cyperaceae) are proposed for taxa occurring in China. All these taxa previously had been placed in Scirpus L. s.l., which has been split into segregate genera in the recent literature. The following transfers are made for taxa originally described from China: Schoenoplectus chuanus (Tang & F. T. Wang) S. Yun Liang & S. R. Zhang, its type from Jiangsu; S. jingmenensis (Tang & F. T. Wang) S. Yun Liang & S. R. Zhang, from Hubei; S. mono- cephalus (J. Q. He) S. Yun Liang & S. R. Zhang, from Anhui; S. pseudoarticulatus (L. K. Dai & S. M. Huang) S. Yun Liang & S. R. Zhang, from Hainan; and S. supinus (L.) Palla subsp. densicorrugatus (Tang & F. T. Wang) S. Yun Liang & S. R. Zhang, from Xinjiang.
Key words: China, Cyperaceae, Schoenoplectus,
The genus Scirpus L. (Cyperaceae) has been demonstrated to be heterogeneous, and it has been split into segregate genera (Wilson, 1981; Haines & Lye, 1983; Zhan & Yang, 1987a, b, c; Bruhl, 1995; Goetghebeur, 1998; Kukkonen, 1998; Muasya et al., 1998, 2000, 2001; Smith & Hayasaka, 2001, 2002; Pignotti & Mariotti, 2004). Although previously treated as a single genus in Flora Reipublicae Popularis Simcae (Tang & Wang, 1961), Chinese Scirpus s.l. segregates into the six genera Act inoscirpus (Ohwi) R. W. Haines & Lye, Bolboschoenus (Asch.) Palla, Isolepis R. Br., Schoenoplectus (Rchb.) Palla, Scirpus, and Tricho- phorum Pers.

Abstract . A new species of Camellia L. (Theaceae), C. maiana Orel, endemic to the Da Lat Plateau in southern Vietnam, is described and illustrated. The newly described species has variable-sized, ovate to obovate leaves; 2-whorled, terminal, sessile flowers
finely textured petals; a compound style consisting of four parts that are fused at the base; persistent bracteoles; and a superior 4-chambered ( morphological evidence supports taxonomic place¬ ment as a transitional member of Camellia sect. Stereocarpus (Pierre) Sealy.
Key words: Camellia, IUCN Red List, Theaceae,
Camellia L. is a member of the tea family (Theaceae). This genus is well represented in
areas of the country. Vietnam is considered a major center of diversity for Camellia, having approximately 20% of all the species located within its boundaries (Sealy, 1958; Chang & Bartholomew, 1984). The genus Camellia is characterized within the family by having seeds without wings and capsules dehiscing from the apex (Sealy, 1958).
In this paper, a new species within Camellia sect. Stereocarpus (Pierre) Sealy from Vietnam is described. As the infrageneric classification of the genus varies from author to author, in this study, the taxonomic treatments of Sealy (1958), Chang and Bartholomew (1984), and Ming and Bartholomew (2007) are considered. This section was originally established by Pierre in 1887 and. as constituted by Chang and Bartholomew (1984), it contains five species, namely C. dormoyana (Pierre ex Laness.) Sealy, C. krempfii (Gagnep.) Sealy, C. yunnanensis (Pit. ex Diels) Cohen- Stuart, C. liberistyla Hung T. Chang, and C. liberistyloides Hung T. Chang (Chang & Bartholomew, 1984). In Ming and Bartholomew’s classification system (2007), Camellia sect. Stereocarpus contains three species, C. dormoyana (the type species), C. pubipetala Y. Wan & S. Z. Huang, and C. luteoflora Y. K. Li ex Hung T. Chang & F. A. Zeng.

The new species also shares some affinities with the members of section Fuifuraceae; however, placement of the proposed new Camellia species into section Fuifuraceae was also judged inappropriate, as the morphological traits in common were only superficial. In similar cases, Sealy (1958) and Chang and Bartholomew (1984) deemed such species “transition¬ al”; we have followed Sealy’s approach and consider the new species proposed here to be transitional in

Synonymy within Alfaroa manningii
I described Alfaroa guanacastensis D. E. Stone in 1977 as a segregate of A. manningii based on perceived differences in their respective leaf and nut morphology (short vs. long leaf petioles, low vs. pronounced ribs on the fruit husk, respectively) and geographic ranges (Pacific vs. Atlantic watershed in Costa Rica). Subsequent collections of these two taxa,
as well as a more comprehensive overview of Alfaroa throughout Latin America, make a clear distinction between them untenable. It appears now that we are dealing with a series of disjunct populations that are
A. guanacastensis is hereby reduced to synonymy under A. manningii (Leon, 1953).

Relationship of Alfaroa and Alfaropsis The genus Alfaropsis (Iljinskaya, 1993) is most commonly recognized as Engelhardia roxburghiana
Psilocarpeae Nagel emend. Leroy (Manning, 1966, 1978). It shares winged fruits with the Old World Engelhardia (Jacobs, 1960) and New World Oreo- munnea (Manning, 1959). Oreomunnea, on the other hand, is the closest relative of Alfaroa (Manos & Stone, 2001), even though the latter has wingless, drupaceous fruits (Stone, 1977). There has been considerable conjecture as to the validity of recog-
relative to Alfaroa (Manning, 1949; Stone, 1972), since they are virtually impossible to tell apart except for the distinctive pistillate flowers and fruits (Table 2). Support for recognition of Oersted’s Or¬ eomunnea (1856) was provided by Hjelmqvist (1948, 1960) and Leroy (1951) based on floral morphology, by Stone (1972) emphasizing the fruit and patterns of germination, and subsequently by Manchester (1987)
Iljinskaya reviewed the taxonomy and phylogeny of the family and concluded, among other things, that E. roxburghiana should be treated as a species of Alfaroa, namely A. roxburghiana (Wall.) Iljinsk.
due perhaps in part to our translation from Russian, she did make the case for recognizing this taxon as a link between Engelhardia sect. Engelhardia and the

Noteworthy remarks on various aspects of the distribu¬ tion, ecology, conservation, and biology of members of the family are also included. When compiling the taxonomic and nomenclatural data for the synopsis of Gymnomitriaceae, the authors found that some taxa

Ribes frankei Weigend & Breitkopf is possibly the most aberrant species of Ribes — it is a small, cushion-forming dwarf-shrub to 30 cm tall, with erect inflorescences that are virtually immersed in the leafy cushions. It is the smallest species of Ribes known so far and has been collected on vertical rock faces in the high Andes of Pasco in central Peru. The species total for Peruvian Ribes now reaches 23, which is nearly twice the number of species known for any other individual South American country,

Section Andina is widespread from southern Central America to Bolivia and reaches Argentina with a single species (Weigend & Binder, 2001). Ribes subg. Parilla sect.

Novon, A Journal for Botanical Nomenclature from the Missouri Botanical Garden
The mission of the Missouri Botanical Garden is to discover and share knowledge about plants and their environment, in order to preserve and enrich life.
Novon publishes short articles whose primary purpose is the establishment of nomencla¬ ture in vascular plants and bryophytes. All articles are peer-reviewed by qualified, indepen¬ dent reviewers.
Manuscripts must fully state and justify the reasons for proposing nova. These may include detailed comparisons with similar taxa, short keys to similar taxa, illustrations to similar taxa, and mechanical nomenclature reasons, among others. Manuscripts whose primary purpose is other than establishment of new nomenclature, which usually are longer manuscripts, cannot be accepted for review. These include reviews, revisions, monographs, or other papers that incidentally include nova.
Manuscripts must follow the guidelines in the Checklist for Authors. The Checklist may be downloaded from the Garden’s web site, www.mbgpress.org, or authors may contact the man¬ aging editor to request a copy.
Novon will not knowingly accept manuscripts that have been simultaneously submitted to other journals for consideration or previously published in some form elsewhere.

The Eastern Arc Mountains and coastal forests of Tanzania and Kenya are well known to support a high diversity of both plants and animals with extremely high concentrations of rare and endemic species (Myers et al., 2000; Critical Ecosystem Partnership Fund, 2003; Burgess et al., 2007; Hall et al., 2009). Recent and ongoing botanical exploration in this area continues to add to this number (e.g., Gereau & Bodine, 2005; Lantz & Gereau, 2005; Couvreur et al., 2006). Continuing this trend, three new species in two genera of Rubiaceae are described below.

species of Aidia, have resinous exudates. Aidia is distinguished within the Gardenieae by triangular stipules that are either shortly fused around the stem or free and interpetiolar; hermaphroditic 4- or 5-merous flowers; corolla lobes convolute in bud and overlapping to the left, 2 (rarely 3)-locular ovaries with numerous ovules on peltate; axile placentas; baccate fruits; and a
cences are congested to laxly cymose and borne on one
node in a pseudoaxillary or supraaxillary position. The inflorescence is sometimes positioned opposite a developed leaf but with the subtending leaf reduced or apparently lacking, or sometimes the node bearing the inflorescence is apparently leafless, with the leaf opposite the inflorescence reduced to an inconspicuous scale. The flowers often have secondary pollen presentation, with the non-receptive outer surface of the stigma forming an oblongoid to clavate, ridged

IUCN Red List category. The evidently rare and localized Galium sichuanense has not been collected since 1989. Because it grows in a forested area that is evidently not protected, its conservation assessment should be classified as Endangered (EN) according to IUCN Red List criteria (IUCN, 2001).
Phenology. According to the type specimen, Galium sichuanense appears to flower from July to August and to fruit from August to September.
Discussion. At the present time, only two collec¬ tions of Galium sichuanense are known from the type locality. The new species is morphologically isolated and not closely related to any other species of the
hemicryptophytic growth form, the partly retrorsely aculeolate leaf margins, and the fruits with uncinate
characteristic of Galium sect. Hylaea (Griseb.) Ehrend. (Ehrendorfer et al., 2005). Nevertheless, the combination of the branching pattern, the membra¬ nous leaves, the predominantly glabrescent stems and leaves, the leafy inflorescences, and the small flowers separate it clearly from all other members of these two

Herbarium (PE), Institute of Botany, Chinese Academy of Sciences, 20 Nanxinchun, Xiangshan, Beijing 100093, People’s Republic of China, xiaohuajin@ibcas.ac.cn
Abstract. Liparis cordifolia Hook. f. var. gongsha¬ nensis X. H. Jin (Orchidaceae, Malaxideae) is
typical variety by having larger flowers with the sepals and petals ca. 1.1 cm long (vs. 0.8-0.9 cm in variety cordifolia ) and a circular, ciliate lip with a pair of small calli at the base (vs. lip obovate-deltoid, entire, and ecallose in variety cordifolia). The new variety appears to be restricted to evergreen humid forest in the Dulong River valley (upper portion of the Irrawaddy River), from Yunnan, China. A lectotype is designated for L. cordifolia.

The genus Liparis Rich. s.l. (Orchidaceae, Malax¬ ideae) consists of 150 to 320 species distributed in the

Liparis was by Ridley (1886), in which 110 species were recognized, and many new species have been published since that time. Recently, more small genera have been segregated from Liparis s.l., e.g., Alatiliparis Marg. & Szlach., Disticholiparis Marg. & Szlach., and Ypsilorchis Z. J. Liu, S. C. Chen & L. J. Chen. The taxonomy of this genus is very confused
Margonska & Szlachetko, 2001, 2004; Pridgeon et al., 2005; Liu et al., 2008). Liparis s.l. is followed here because most of the previous generic treatments of Liparis either lack sound phylogenetic analysis or are
There are about 50 to 60 species of Liparis in China (Chen, 1999; Chen et al., 2009), including many recently described species from China or neighboring
2007; Yang et al., 2009). During fieldwork in the Gaoligong Mountains, northwestern Yunnan, China, in 2008, a new variety of L. cordifolia was discovered and is described here.

Phenology. Passiflora madidiana has been found with flowers and fruits from late November to early December and in fruit in February. The new species seems to be synchronized with the pronounced changes in temperature and humidity of the rainy season, which starts with torrential rains in November and lasts until March-April.

A New Endemic Species in Trichophorum (Cyperaceae) from South Korea
Jongduk Jung and Hong-Keun Choi *

Abstract. Trichophorum dioicum J. Jung & H. K. Choi (Cyperaceae) was observed growing on limestone
won-do, South Korea. Morphological characteristics of the new species, such as the reduced leaf blade and the single spikelet at the culm terminus, correspond to Trichophorum Pers., a sister genus among Scirpus L. s.l. Previous molecular analysis of the chloroplast rbcL gene and ITS region of nuclear ribosomal DNA supported the identity of this new endemic species

However, the type was not specified and the name was invalidly published (cf. Art. 37.7, McNeill et al., 2006). Lee and Oh (2006b) maintained a broad concept of Scirpus L., which included numerous taxa such as Trichophorum Pers., Bolboschoenus (Asch.) Palla, and Schoenoplectus (Rchb.) Palla. Later, in the same year, the same authors reported a new genus, as “ Neoscirpus ,” based on the characteristics of their dioecious sedge (Lee & Oh, 2006a: 25). However, the
established upon the invalid name from 2006.
Scirpus s.l. has been recognized as a polyphyletic group and is generally accepted as a taxonomic complex of several genera (Koyama, 1978; Bruhl, 1995; Goetghebeur, 1998). One segregated genus, Tri¬
bracts, and an inflorescence with a single or few spikelets and bisexual flowers (Goetghebeur, 1998). Moreover, a molecular phylogenetic study based on analyses of the chloroplast rbcL gene and tmL-F

and nuclear ITS DNA sequences display greater similarity to the type of Trichophorum (T. alpinum (L.) Pers.) than to other species of Scirpus s.l. (unpub¬ lished GenBank accession numbers FJ797640 and FJ797641). We suggest that the new taxon does not belong to Scirpus and that its phylogenetic identity lies within Trichophorum, which is caespitose and rhizomatous, and has ligulate leaves, a reduced leaf blade, and a single spikelet at the culm terminus.
