中国栓翅芹属一新亚种及有关该属的评注

A NEW SUBSPECIES OF PRANGOS AND NOTES ON CHINESE SPECIES OF THE GENUS

本文描述了栓翅芹属一新亚种——新疆栓翅芹,并对该亚种和双生隐盘芹叶片作了黄酮体成分分析,前者含槲皮素—3—鼠李糖甙,后者含一种芹菜素碳甙。依据营养体形态和果实结构的相似性,作者同意广义栓翅芹属的观点,即将绵果芹属的部分种和隐盘芹属并入栓翅芹属。至此我国栓翅芹属计有4种,而无绵果芹属的分布。

The present paper described a new subspecies, Prangos herderi (Regel)Herrnst. et Heyn ssp. xinjiangeniss X. Y. Chen et Q. X. Liu, which wasdifferent from the type subspecies found in USSR in its smaller andoblong-ellipsoid fruits and fewer rays. Leaves of the subspecies and of P.didyma (Regel) M. Pimen. et V. Tichomirov have been examined for theirflavonoids; quercetin-3-rutinoside has been detected in the former taxonand a glucosylapigenin in the latter. It is acceptable that the genus PrangosLindl. should include Cryplcdiscus Schrenk and some species originallyplaced in Cachrys L.; thus there are four species of Prangos in China,all of which occur in Xinjiang. A list of names of Chinese species ofthe genus was given.
