A Revision of Some Species of the Genus Phyllostachys (Gramineae-Bambusoideae) (Ⅳ)——Restoration of Phyllostachys hispida and Classification of Its Allied Taxa

Abstract:

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.
