摘要
报道了发现于浙江普陀山岛的2个植物新分类群,分别是桑科Moraceae薜荔Ficus pumila的新变种小果薜荔Fi-cus pumila Linn.var.microcarpa G.Y.Li et Z.H.Chen和杜鹃花科Eriaceae映山红Rhododendron simsii的新变种普陀杜鹃Rhododendron simsii Planch.var.putuoense G.Y.Li et Z.H.Chen。小果薜荔与原变种薜荔Ficus pumila var.pumila的区别是隐花果较小,椭圆形或宽椭圆形,稀近球形,长2.0～4.0cm,直径1.7～2.6cm,顶端钝;果枝之叶明显较小,叶缘通常反卷。普陀杜鹃与原变种映山红Rhododendron simsii var.simsii的区别是花冠紫色。
Two new varieties,Ficus pumila Linn.var.microcarpa G.Y.Li et Z.H.Chen and Rhododendron simsii Planch.var.putuoense G.Y.Li et Z.H.Chen were found on Putuo Island,Zhejiang Province.Compared to F.pumila var.pumila,F.pumila var.microcarpa had smaller achenes,elliptical or broadly elliptical leaves 2.0-4.0 cm in length and 1.7-2.6 cm in diameter with an obtuse apex,smaller leaves on fertile branchlets,and usually a roll down margin.Also,R.simsii var.putuoense,having a purplish red corolla,differed from R.simsii var.simsii.
