摘要
在模式标本考证、居群调查和引种栽培的基础上,确认毛壳竹(Phyllostachys hispida S.C.Li,S.H.Wu et S.Y.Chen)与乌竹(P.varioauriculata S.C.Li et S.H.Wu)在新秆性状、秆箨颜色、箨舌高度及颜色、叶鞘毛被上有较大的区别,应作为独立的竹种看待。小叶光壳竹(P.varioauriculata var.glabrata G.H.Lai)也因新秆下部一段呈扁圆形、秆箨基部具长柔毛,叶片很小等特征而明显不同于乌竹,应提升为一个独立的竹种,但由于存在晚出同名问题而给出新名称P.microphylla G.H.Lai。同时还描述了毛壳竹的一新变种,即光壳竹(P.hispida var.glabrivagina G.H.Lai)。日本所产的姬淡竹与毛壳竹属于同一种系,因其学名P.humilis Muroi为一裸名,应予废弃。
On the basis of examination of the type specimens, investigations of the populations, and transplantation, Phyllostachys varioauriculata S. C. Li et S. H. Wu and its allied taxa are taxonomically discussed and revised. P. hispida S. C. Li, S. H. Wu et S. Y. Chen, which is distinctly different from P. varioauriculata S. C. Li et S. H. Wu by the characters of young culm, colour of culm leaf sheath, height and colour of culm leaf ligule, and indumentum of foliage leaf sheath, is proposed to be an independent species. P. varioauriculata var. glabrata G. H. Lai, owing to many characters （such as young culms oblate at its inferior part, culm leaf sheath villose at base, foliage leaf very small etc.） different from P. varioauriculata S. C. Li et S. H. Wu, is raised as a specific rank and is given a new name P. microphylla G. H. Lai. In addition, a variety, P. hispida var. glabrivagina G. H. Lai, is described as new. P. humilis Muroi, as a nomen nudum was given by some Japanese botanists, which is conspecific with P. hispida S. C. Li, S. H. Wu et S. Y. Chen, is rejected.
