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.
