Paeonia suffruticosa Andrews subsp. spontanea (Rehder) S. G. Haw et L. A.
Lauener ( ＝P. spontanea ＝ P. jishanensis) has been considered as the wild form of widely
cultivated P. suffruticosa. However, the subspecies differs from the cultivated one in
shape, division and indumentum of leaves and reproductive biology. As a result of extensive
field work, a form with two individuals in Yinping Shan, Caohu, Anhui, and Songxian,
Henan, are found to be extremely similar to P. suffruticosa, but apparently different from
P. jishanensis. The form is considered to be the wild one of P. suffruticosa and described as new: P. suffruticosa subsp, yinpingmudan Hong, K. Y. Pan et Z. W. Xie. 相似文献

虎掌叶的发育体现了生物重演律 总被引：1，自引：0，他引：1
虎掌(Pinellia Pedatisecta Schott)又名掌叶半夏,为天南星科半夏属植物,其块茎药用。本实验在前一年的秋季采集虎掌的成熟种子,于第二年的春季单粒盒种。其叶片在一年的春天至秋天里不断地生长、成熟、枯萎、死亡,再在生长的块茎上长出新叶。笔者对其叶子的发育过程进行了连续两年的系统观察,结果如下。 虎掌种子春天播种后,长出的第一枚叶片是心叶,单叶全缘。小块茎上长出的第2枚叶片也为单叶,但叶片两侧向叶基外延,叶基为戟 相似文献
