In addition to describing a new species, Cypripedium wumengense, as well
as a new variety, C. bardolphianum var. zhongdianense, nomenclatural and taxonomic
notes are made on its allies and the division to which they belong. They are ltrge]y
found in the Hengduan Mountains in southwestern China, characterized by the absence
of bract, havirg lip more or less covered with small wart-like outgrowths, and that as
the capsule matures the scape becomes much elongated. Six species of this group have
hitherto been reported, of which, however, C. ebracteatum and C. nutans are regarded
here as conspecific with C. fargesii and C. bardolphianum respectively. Thus, including
the new taxa described here, it composes five species and one variety: C. bardolphianum
W. W. Sm. et Farrer (var. bardolphianum and var. zhongdianense S. C. Chen), C. mic-
ranthum Franch., C. fargesii Franch., C. margaritaceum Franch. and C. wumengense
S. C. Chen. They are all grouped here into the same section, Sect. Trigonopedium
(Franch.) Pfitz., the oldest legitimate name of this group in the rank of section. 相似文献

对新种小囊兜兰Paphiopedilum globulosum与新变种扁球兜兰P．micranthum var．oblatum作了描述与绘图。两者均为采自云南东南部的栽培植物，与硬叶兜兰P．micranthum近似。但小囊兜兰具有宽得多的叶(宽2．8～3．4cm)，先端多少呈钩状、宽1．1～1．2cm的唇瓣，以及与唇瓣囊口几乎同样大小的退化雄蕊，而扁球兜兰则叶宽2．2～3 cm，唇瓣扁球形，囊深不超过1 cm，可区别于硬叶兜兰。上述种类均属于宽瓣亚属(广义）。该亚属有16个种产中国、越南或两地共有。本文提供了分种检索表。 相似文献
