石竹科齿瓣无心菜属2新组合名称

Two New Combinations in Odontostemma (Caryophyllaceae)

摘要:

基于近年来分子系统学研究结果，石竹科无心菜属（Arenaria L.）齿瓣亚属[subgen. Odontostemma（G. Don）Williams]在属水平的地位得以恢复，该亚属中相关物种名也因此被组合至齿瓣无心菜属（Odontostemma Benth. ex G. Don）之中。然而，中国所产道孚无心菜（A. dawuensis A. J. Li&Q. Ban）与神农架无心菜（A. shennongjiaensis Z. E. Zhao&Z. H. Shen）在相关处理中被遗漏，故在此给予其新的组合名称：O. dawuense（A. J. Li&Q. Ban）G. Yao和O. shennongjiaense（Z. E. Zhao&Z. H. Shen）G. Yao。

Abstract:

Results from recent molecular phylogenetic studies indicated that the generic status for the subgenus Odontostemma (G. Don) Williams of Arenaria L. should be reinstated, and thus new combinations for relevant names included in the subgenus were proposed recently. However, the two names A. dawuensis A. J. Li & Q. Ban and A. shennongjiaensis Z. E. Zhao & Z. H. Shen were neglected in previous treatments. Accordingly, two new combinations for the two names are proposed here:O. dawuense (A. J. Li & Q. Ban) G. Yao, O. shennongjiaense (Z. E. Zhao & Z. H. Shen) G. Yao.
