摘要:

算盘子属(Glochidion J. R. & G. Forst.)是叶下珠科(Phyllanthaceae)叶下珠族(Phyllantheae)中一个分类极为困难的类群。基于广泛野外考察与馆藏标本查阅,对中国该属部分物种进行分类学处理。其中,长柱算盘子[G. khasicum(Müll. Arg.)Hook. f.]与倒卵叶算盘子(G. obovatum Siebold & Zucc.)在中国的分布予以排除,菲岛算盘子[G. philippicum (Cav.)C. B. Rob.]在中国被发现仅分布于台湾地区; G. bodinieri H. Lév.,G. pseudo-obscurum var. glabrum Pamp.与G. pseudo-obscurum var. lanceolatum Pamp.这三个名称被处理为湖北算盘子(G. wilsonii Hutch.)的新异名; G. vaniotii H. Lév.被排除在算盘子属外,并接受为芸香科臭常春(Orixa japonica Thunb.)的异名。另外,对G. khasicum(Müll. Arg.)Hook. f., G. obovatum Siebold & Zucc., G. philippicum(Cav.)C. B. Rob.,G. pseudo-obscurum var. lanceolatum Pamp.及G. wilsonii Hutch.这五个名称进行了后选模式的指定。

Abstract:

Glochidion J. R. & G. Forst. is a taxonomically difficult genus within the tribe Phyllantheae of the family Phyllanthaceae. In this paper, some species of the genus from China are taxonomically revised. The distribution of G. khasicum(Müll. Arg.)Hook. f. and G. obovatum Siebold & Zucc. in China, as well as the distribution of G. philippicum (Cav.)C. B. Rob. in mainland China, Hainan and Hong Kong, are all excluded. The three names Glochidion bodinieri H. Lév., G. pseudo-obscurum var. glabrum Pamp. and G. pseudo-obscurum var. lanceolatum Pamp. are accepted as the new synonyms of G. wilsonii Hutch., while the name G. vaniotii H. Lév. is excluded from Glochidion and accepted as the synonym of Orixa japonica Thunb. Additionally, the five names Glochidion khasicum(Müll. Arg.)Hook. f., G. obovatum Siebold & Zucc., G. philippicum(Cav.)C. B. Rob., G. pseudo-obscurum var. lanceolatum Pamp. and G. wilsonii Hutch. are lectotypified here
