摘要
卫矛科永瓣藤属(Monimopetlum)特产我国,只有一种,即永瓣藤(M.Chinense Rend.)本文报道了通过光学显微镜、扫描电镜、透射电镜对其花粉外壁进行系统研究的结果。从花粉形状、萌发孔类型以及外壁超微结构看,永瓣藤花粉应是卫矛科(Celastraceae)中的一个独特类型。
Monimopetalum chinense Rehd. is endemic to China. The pollen morphology and exine ultrastructure were examined under LM, SEM and TEM.
On the basis of pollen shape, type apperture and exine ultrastructure the pollen grains of Monimopetalum chinense are distinguishable, from those of other genera in Celastraceae and it may belong to a new type of Celastraceae.
