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
