| 摘 要： | 该文发表采自安徽的一个薹草属新种,即类嵩薹草(Carex kobresiformisS.W.Su),该种在其侧生小穗上的几乎所有的果胞都有发育良好的生有2~5枚雄花的次生小穗轴,从而形成为两性支小穗.这不仅与Schoenoxiphium以及嵩草属(Kobresia)的支小穗具有相似的结构,而且其整个侧生小穗也与嵩草属的穗状花序相似.作者曾从野外挖掘完整植株带回住地栽培,经过数年观察,确证其由果胞发出的两性支小穗的性状是极其稳定的,这或许是返祖演化的结果,在薹草属(Carex)中是极为奇特、极为罕见的.

| Abstract: | A new species of genus Carex was described from Anhui province,China,i.e Carex kobresiformis S.W.Su.The new species reported in this paper is a particular species of Carex,and its spikelet may be regarded as a primitive form of atavistic spikelets in Carex.Almost all the utricles of lateral spikelets have been found with a well-developed rachilla bearing 2-5 male flowers,and actually have become bisexual partial spikelets.C.kobresiformis is not only quite the same in the structure of partial spikelet as tha... |
