摘要

A new species, Saussurea rolwalingensis (subgenus Saussurea section Cyathidium) is described from the Nepal Himalaya. It differs from S. donkiah C. B. Clarke ex L. S. Springate in having a well-developed fibrous rhizome and tubular involucres. Morphological comparisons between the new species and allied members of sect. Cyathidium from Nepal are presented. Saussurea DC. subgenus Saussurea section Cyathidium (Lindl. ex Royle) Ling is distributed in the alpine to the subnival zones of the Himalayas andCentral Asia and is characterized by pinnatisect leaves and a single capitulum borne on a simple stem (Lipschitz 1979). Eight species are currently recognized from the Nepal Himalaya; Saussurea polystichoides Hook, f., S. leonto-dontoides (DC.) Sch. Bip., S. sughoo C. B. Clarke, S. nepalensis Spreng., S. taraxaci-folia Wall, ex DC., S. roylei (DC.) Sch. Bip., S. stoliczkae C. B. Clarke, S. donkiah C. B. Clarke ex L. S. Springate (Lipschitz 1979, Chater and Kitamura 1982, Grierson and Springate 2000, Fujikawa et al. 2007). During the fieldwork towards a revision of Saussurea for the Flora of Nepal, a number of interesting plants belonging to subgen. Saussurea sect. Cyathidium were collected at Rolwaling, Central Nepal in 1983 (Anonymous 1986, Ohba 2002). A specimen among these collections superficially resembled S. donkiah, but was subsequently found to differ from the latter in the presence of a fibrous rhizome as well as several other morphological characters, as shown in Table 1. The material is formally recognized as a new species here, and a full description and illustration are presented below.

Springate）的不同之处在于其具有发达的纤维状根状茎和管状小囊。新物种与该教派的盟友之间的形态比较。介绍了来自尼泊尔的Cyathidium。雪莲DC。雪莲亚种Cyathidium（Lindl。ex Royle）Ling在高山分布到喜马拉雅山和中亚的亚下带，其特征是羽状叶和单茎生于简单的茎上（Lipschitz 1979）。目前，尼泊尔喜马拉雅山地区已确认有8种。 Saussurea polystichoides Hook，f。，S. leonto-dontoides（DC。）Sch。 Bip。，S. sughoo C. B. Clarke，S. nepalensis Spreng。，S. taraxaci-folia Wall，ex DC。，S. roylei（DC。）Sch。 Bip。，S。stoliczkae C. B. Clarke，S。donkiah C. B. Clarke，前L.S. Springate（Lipschitz 1979，Chatter和Kitamura 1982，Grierson and Springate 2000，Fujikawa等2007）。在对索苏拉（Saussurea）进行尼泊尔植物群修订的实地调查中，许多有趣的植物都属于亚基因。索苏拉教派。 1983年在尼泊尔中部Rolwaling收集了Cyathidium（Anonymous 1986，Ohba 2002）。这些样本中的一个样本表面上类似于S. donkiah，但随后发现它与后者不同，因为它具有纤维状根茎以及其他几个形态特征，如表1所示。该物质被正式认为是新物种。此处，下面提供了完整的描述和说明。
