Kurz.in Zhejiang. (2) It is verified that G. fortunei Hance is a new synonym of G.rubrum Blume; the legitimate names of Mallotus repandus (Willd.) Müll. Arg.var.scabrifolius (A.Juss.) Müll.Arg.,Mallotus apelta (Lour.) Müll.Arg.and M.tenuifolius Pax are justified,and M.tenuifolius Pax var.subjaponicus Croizat is actually to a synonym of M.japonicus (L.f.) Müll.Arg.. (3) Phyllanthus glaucus Wall.ex Müll.Arg.var.trichocladus P.L.Chiu ex Z.H.Chen is a new variety; Phyllanthus amarus Shumach.& Thonn.and Breynia officinalis Hemsl. are new records in Zhejiang.
