Abstract:
Evidence is provided in the present article to confirm the generic status of Xizangia.
This genus is distinctly different from Pterygiella in having rhizomes with winter buds, serrate leav-
es, unequally cleft calyx (up to 2/3 in length at anterior), and bubblelike and smooth seed-coat. A
new combination, Xizangia bartschioides (Hand.-Mazz.) D. Y. Hong is thus made, and Xizangia
serrata D. Y. Hong and Pterygiella bartschioides Hand.-Mazz. are treated as synonymy.
