A Revision of Some Species of the Genus Phyllostachys (Gramineae—Bambusoideae)(Ⅴ)

Based on complex observation of type materials,real photos and collections,investigation of type locality and examination of original descriptions,some taxonomically uncertain Latin names under Phyllostachys Sieb.et Zucc.were discussed and verified.As a result,P.sapida Yi (=P.arcana McClure),P.balansae Nguyen (=P.bambusoides Sieb.et Zucc.),P.subulata W.T.Lin et Z.M.Wu (=P.bambusoides Sieb.et Zucc.f.shouzhu Yi),P.cantoniensis W.T.Lin (=P.heteroclada Oliv.),P.lofushanensis C.P.Wang et al.(=P.nidularia Munro f.basipilis G.H.Lai),P.aristata W.T.Lin (=P.nidularia Munro f.basipilis G.H.Lai),P.guizhouensis C.S.Chao et J.Q.Zhang (=P.nigra (Lodd.ex Lindl.) Munro var.henonis (Mitf.) Stapf ex Rendle),and P.lithophila Hayata (=P.sulphurea (Carr.) A.et C.Riv.var.viridis R.A.Young) were all reduced to synonyms;the systematic position of three species from Vietnam was proposed:P.caobangensis Nguyen may possibly be conspecific with P.bambusoides Sieb.et Zucc.,and P.baccanensis Nguyen and P.vietbacensis Nguyen conspecific with P.kwangsiensis W.Y.Hsiung et al.
