| 摘 要： | 虽然玄参科的马松蒿Xizangia serrata D．Y．Hong与齿叶翅茎草Petrygiella artschioides Hand．-Mazz．系同物异名，但齿叶翅茎草与翅茎草属其余4种植物在习性、叶、花萼等外部形态上有显著差异，在种皮方面的差异尤为突出。马松蒿属Xizangia 作为属的地位是合适的。因此，本文作了一个新组合，即XI-zangia bartschioides(Hand．-Mazz．)D．Y．Hong，而把Ptertrygiella bartschioides Hand．-Mazz．和Xizangia serrata D．Y. Hong均作异名处理。

| 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 Xizangiaserrata D. Y. Hong and Pterygiella bartschioides Hand.-Mazz. are treated as synonymy. |
