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

基于对许多活植物的观察，对兰科中兰属的若干种类进行了分类学考订，结果承认菅草兰Cymbidium tortisepalum与峨眉春蕙C. omeiense为独立的种，将春剑C. longibracteatum移至菅草兰之下作为变种，送春C. szechuanicum移至莎叶兰C. cyperifolium之下作为变种。由于春剑、峨眉春蕙和送春的模式标本及引证标本已在30多年前全部丢失，本文指定了新模式。 相似文献

The present paper deals with a comparative karyotypic study of three species in Fri-
tillaria-F. thuncergii Miq., F. anhuiensis S. . Chen et S. F. Yin and F. hupehensis Hsiao et
K. C. Hsia. The karyotype of F. anhuiensis S. C. Chen et S. F. Yin is first reported.
The karyotypes of the three species of Fritillaria are rather similar, all with K(2n)=24=
2m+2sm+12t+4st+4m (SAT), showing a close interspecific relationship. They all have two
pairs of st chromosomes, one of which is the third chromosome in all the three species studied,
but the other is the seventh in F. thunbergii Miq, the eighth in F. anhuiensis S. C. Chen et S. F.
Yin, and the fifth in F. hupehensis Hsiao et K. C. Hsia. It tells us that there are some differences
in their karyotypes. All of the three species possess two pairs of satellite chromosomes with the
satellites located on the long arms. A heterochromatic zone is found sometimes on long arms of No.
IX chromosome in each species of Fritillaria and on one of No. I chromosomes in both F. thun-
bergii Miq. and F. anhuiensis S. C. Chen et S. F. Yin, a chromosome polymorphism occurring
between populations of Fritillaria. In addition, three B chromosomes are always found in most
root-tip cells of F. hupehensis Hsiao et K. C. Hsiao. 相似文献
