Anemone fulingensis W. T. Wang & Z. Y. Liu, a new species of the Ranunculaceae discovered from Fuling, Chongqing, China, is described and illustracted. In having sessile involucre bracts, 4-5-sepalled flowers, filiform filaments, and pantocolpate pollen it should be a member of Anemone sect. Stolonifera (Ulbr.) Juz., and from all other species of that section differs in its peculiar moniliform rhizome consisting of 2-10 tubers. In view of the fact that in Anemone the tubers are present in certain different evolutionary lines, and their appearance is a secondary phenomenon, this new species should be considered advanced in sect.

中国重庆毛茛科银莲花属一新种——涪陵银莲花 总被引:1,自引:0,他引:1
描述了中国重庆市涪陵区的毛莨科Ranunculaceae银莲花属Anemone一新种——涪陵银莲花A.fulingensisW.T.Wang&Z.Y.Liu,并绘出墨线图。根据此新种的总苞苞片无柄,花具4-5枚萼片,花丝丝形,花粉具散沟等特征,可以确定此种应是属于银莲花属鹅掌草组Anemone sect.Stolonifera的一个成员;在该组中,此种以其独特的由2-10个块茎组成的念珠状根状茎而与该组的其他种相区别。鉴于在银莲花属中块茎出现于不同的演化路线中,以及这些块茎的出现系次生现象,可见此新种应是鹅掌草组的进化种。 相似文献
