Gymnosporia thyrsiflora comb. nov. (Celastraceae), a correct name to replace G. graciliramula from southwest China

In ‘Flora of China’, the combination ‘Gymnosporia graciliramula (S. J. Pei & Y. H. Li) Q. R. Liu & Funston’ was proposed, but this name was not validly published in 2008 because the presumed basionym Maytenus graciliramula S. J. Pei & Y. H. Li was not published in 1979 as stated, but in 1981, contrary to Article 33.4 of ICBN. Meanwhile, two older names, M. thyrsiflora S. J. Pei & Y. H. Li and M. pseudoracemosa S. J. Pei & Y. H. Li, were listed as synonyms in conflict with article 52.3 of ICBN. In this article, we propose a new combination G. thyrsiflora (S. J. Pei & Y. H. Li) W. B. Yu & D. Z. Li that is the correct name when G. thyrsiflora, M. pseudoracemosa and M. graciliramula are treated as a single species in Gymnosporia.     

Elatostema densistriolatum sp. nov., E. latistipulum sp. nov. and E. cyrtandrifolium var. hirsutum var. nov. (Urticaceae) from southwest China

Two new species and one new variety of Elatostema J. R. Forst. & G. Forst. (Urticaceae) are described from Yunnan and Xizang, China. Habitat details and morphological comparison with similar species are given and discussed. The new taxa proposed are: Elatostema densistriolatum W. T. Wang & Zeng. Y. Wu, E. latistipulum W. T. Wang & Zeng Y. Wu and E. cyrtandrifolium (Zoll. & Mor.) Miq. var. hirsutum W. T. Wang & Zeng Y. Wu.     

A revision of Elatostema section Weddelia series Salvinioida (Urticaceae)

Based on examinations of specimens of Elatostema and Pellionia housed at K, KUN, L, P, PE, and YUNU, Elatostema section Weddelia series Salvinioida is taxonomically revised. Two species are recognized, described, and illustrated, and a key to the species is provided. Elatostema salvinioides var. robustum W.T.Wang is treated as a synonym of E. salvinioides W.T.Wang. Pellionia imbricata Gagnepain is transferred to Elatostema and a lectotype is designated herein. A new name, Elatostema simplicissimum Q. Lin, is provided because Elatostema imbricans was previously occupied. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 62–66.     

Two new species and a new series of Elatostema (Urticaceae) from China

The new series Elatostema section Elatostema series Albopilosoides Q.Lin & L.D.Duan (Urticaceae) is described, and two new species of Elatostema, namely Elatostema albopilosoides Q.Lin & L.D.Duan and Elatostema purpureum Q.Lin & L.D.Duan. from south Guizhou province, south‐west China are described and illustrated. Both species were found growing only at the base of a large limestone chamber at an altitude of c. 800 m. Elatostema albopilosoides is morphologically similar to E. albopilosum W.T.Wang, but differs by having female inflorescences with peduncles 10–60 mm long (0–1.5 mm long in E. albopilosum) and receptacles 7–27 mm long, 7–24 mm wide (E. albopilosum: 1–4 mm long and 1–3 mm wide). Elatostema purpureum is also morphologically similar to E. albopilosum, but has stipules 5–6 mm long, 0.8–1.5 mm wide (4–7 mm long, 1.5–2.8 mm wide in E. albopilosum) and leaf blades obliquely elliptical to obliquely oblong‐obovate, 3.5–7.5 mm long and 1.5–2.5 mm wide (obliquely narrowly oblanceolate‐oblong, 12–17 cm long, 3–5 cm wide in E. purpureum:). © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 674–680.     

The confusing identity of Pternopetalum molle (Apiaceae)

The misapplication of the name Pternopetalum molle (Franch.) Hand.‐Mazz. has resulted in considerable taxonomic confusion in the genus, involving 11 names belonging to seven taxa (according to a recent treatment). A supplementary taxonomic revision of P. botrychioides (Dunn) Hand.‐Mazz., P. molle and P. vulgare (Dunn) Hand.‐Mazz. is presented, after a detailed examination of the morphological variation. Four new synonyms, P. longicaule var. humile R.H.Shan & F.T.Pu, P. molle var. dissectum R.H.Shan & F.T.Pu, P. radiatum (W.W.Smith) P.K.Mukherjee and P. trifoliatum R.H.Shan & F.T.Pu, are proposed. Pternopetalum delicatulum (H.Wolff) Hand.‐Mazz. should be reduced to P. botrychioides rather than P. radiatum. The previous taxonomic treatments of P. cuneifolium (H. Wolff) Hand.‐Mazz., P. cartilagineum C.Y.Wu ex R.H.Shan & F.T.Pu and P. molle var. crenulatum R.H.Shan & F.T.Pu are reinstated. A key and distribution maps are provided for the accepted species. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 274–295.

Duan from Bach Ma Natl. Park, Thua Thien‐Hue Province, Vietnam, is described and illustrated. Pellionia ambigua Wedd. from Khasi Hills, Churra, Assam (=Meghalaya), India and P. rhizomatosa Gagnep. from Annam, Vietnam are transferred as Elatostema ambiguum (Wedd.) Q. Lin and E. rhizomatosum (Gagnep.) Q. Lin, respectively. Elatostema glochidioides W. T. Wang from Guangxi and Guizhou and Provinces, China is regarded as a new synonym of E. ramosissimum Rein.     

四川乌头属的修订

四川是我国乌头属Aconitum L.植物的重要分布区。本文对该地区的乌头属植物进行了分类修订。通过文献查阅、野外观察和标本室研究,对乌头属的形态性状在居群间和居群内的变异式样进行了比较分析,发现叶分裂程度、上萼片的形状和花梗毛被等性状是较为可靠的分种依据,但是在个别情况,这些性状也会在同一种的同一居群内或不同居群间发生变化。花瓣和种子的特征对于属下划分有重要意义。本文承认四川乌头属植物有46种11变种,另有2种和1变种暂存疑。29种和22变种降为异名;作出新组合2个,其中包括1个改级新组合。紫乌头A. delavayi Franch.和保山乌头A. nagarum Stapf为四川新分布记录。对康定乌头A. tatsienense Finet &; Gagnep.、川鄂乌头A. henryi Pritz.和狭裂乌头A. refractum (Finet &; Gagnep.) Hand.-Mazz.进行了后选模式的标定。初步澄清了东俄洛乌头A. tongolense Ulbr.和狭裂乌头等种类中长期存在的名实混乱。还给出了各个种的形态描述、地理分布以及分亚属、分系和分种检索表。     

A new species of Polygala L. (Polygalaceae) from south‐west Anatolia

Polygala peshmenii Eren, Parolly, Raus & Kürschner is described and illustrated as a new species from Antalya province in south‐west Anatolia, Turkey. Within subgenus Polygala section Polygala, it seems to be taxonomically quite isolated. As far as the Flora of Turkey area is concerned, technical comparison can be made with the informal P. alpestris Rchb. and P. vulgaris L. groups. The habitat conditions of P. peshmenii and its conservation status are considered. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158 , 82–86.     

丹霞柿，广东柿属(柿科)一新组合及其一新异名

通过查阅模式标本后发现丹霞南烛(Lyonia danxiaensis R. H. MiaoW. Q. Liu)具有聚伞花序,花部为4数,雄蕊16枚且成对着生,花丝非膝曲状等特征与珍珠花属(Lyonia)不符,而与柿科(Ebenaceae)柿属(Diospyros)一致,因此提出一新组合:丹霞柿[Diospyros danxiaensis (R. H. MiaoW. Q. Liu) Y. H. TongN. H. Xia]。且经标本比对后发现,新近发表的彭华柿(Diospyros penghuae W. B. Liao, Q. FanW. Y. Zhao)与丹霞柿实为同种,在此也予以合并。     

Taxonomy of the Onosma echioides (L.) L. complex (Boraginaceae) based on morphometric analysis

A morphometric study on five populations of the Onosma echioides complex was carried out through univariate analysis, principal coordinate analysis and cluster analysis (the unweighted pair‐group method with arithmetic mean; UPGMA). In consideration of the quantitative morphological variability, of the known karyological homogeneity and of the allopatric distribution of the taxa, we propose here to treat this complex as a single species subdivided in four subspecies. The names O. angustifolia Lehm., O. canescens J. et C. Presl, O. dalmatica Scheele, O. echioides var. columnae Lacaita, O. echioides var. veronensis Lacaita and O. javorkae Simonkai are typified. The new combinations O. echioides subsp. angustifolia (Lehm.) Peruzzi & N. G. Passal., O. echioides subsp. canescens (J. et C. Presl) Peruzzi & N. G. Passal. and O. echioides subsp. dalmatica (Scheele) Peruzzi & N. G. Passal. are proposed. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 157 , 763–774.

Surprisingly high orchid diversity in travertine and forest areas in the Huanglong valley, China, and implications for conservation

The presence of such a large number of terrestrial orchid species in a small area (ca. 1 km²) of the Huanglong valley in southwestern China is uncommon for this country. Studying the relationship between the distribution patterns of these orchid species and their microenvironments may help us understand this uncommon phenomenon. We established 662 1 m × 1 m plots, measured the cover of each species and found that there were 33 orchid species distributed mainly in two different habitats, i.e. travertine areas and forest. In the travertine areas, 30 orchid species were found; the six most common ones being Cypripedium bardolphianum, Cypripedium flavum, Cypripedium tibeticum, Galearis diantha, Ponerorchis chusua and Phaius delavayi. However in the forested habitat, we found 21 orchid species; the most common ones being Tipularia szechuanica and Goodyera repens. Travertine areas had a higher number of orchid species as well as higher numbers of orchid species per plot as compared to forest. Light availability seems critical to the performance and distribution of orchid species. Stream flow through the travertine area during the orchids growing season appears to be an important factor in shaping and maintaining stable microenvironments favorable to the growth and reproduction of orchids. The results presented in this study suggest that some orchid species in the travertine area might be threatened if the travertine stream flows were to change or be disrupted.

Phylogenetic position of the genus Bryhnia Kaurin (Brachytheciaceae,Bryophyta) inferred from chloroplast (rpl16, trnG,trnL–F) and nuclear (ITS) sequence data

Abstract

The systematic position of the genus Bryhnia Kaurin has been problematic and remains unsettled. A phylogenetic analysis of Bryhnia and closely related genera, based on the nuclear marker ITS1–5·8S–ITS2 and the plastid markers rpl16, trnG, and trnL–F, was carried out to clarify their relationships and systematic positions. The phylogenetic trees generated from Maximum parsimony and Bayesian analyses show that Bryhnia s.s., represented by B. novae-angliae (Sull. & Lesq.) Grout, B. hultenii E.B.Bartram, and B. scabrida (Lindb.) Kaurin, forms a maximally supported clade nested within Brachythecium Schimp. ‘Bryhnia scabrida’ sensu is Bryhnia brachycladula Cardot, and together they form a monophyletic group with Eurhynchiadelphus eustegia (Besch.) Ignatov & Huttunen and Myuroclada maximowiczii (G.G.Borshch.) Steere & W.B.Schofield. We propose the inclusion of the species currently recognized in Bryhnia in Brachythecium, with the transfer of Bryhnia brachycladula to the genus Myuroclada Besch. Bryhnia brachycladula is further treated as a synonym of the new combination, Myuroclada longiramea (Müll.Hal.) M.Li, Y.F.Wang, M.S.Ignatov & S.Huttunen.
