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 Xizangia

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

Key words： New combination; Xizangia bartschioides; Scrophulariaceae; morphology; seed-coat
