Abstract:

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.

Key words: Cypripedium wumengense, C.bardolphianum, C.bardolphianum var.zhongdianense, C.micranthum, C.margaritaceum, C.fargesii, Sect.Trigonopedium.
