摘要
虽然玄参科的马松蒿XizangiaserrataD .Y .Hong与齿叶翅茎草PetrygiellabartschioidesHand . 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Xizangiabartschioides(Hand . Mazz.)D .Y .Hong,而把PterygiellabartschioidesHand . Mazz.和XizangiaserrataD .Y .Hong均作异名处理。
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 leaves, 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.
