Abstract

<p>Since Desmodium (Leguminosae) was recognized as polyphyletic in 2018, it has been revised to reflect the monophyletic relationships of the species. This paper deals with the last two remaining species previously placed in Desmodium in Asia and Australia, D. varians (Labill.) G.Don and D. siamense (Schindl.) Craib. The former is transferred to Grona, as G. varians (Labill.) H.Ohashi & K.Ohashi, comb. nov., based on molecular phylogenetic analyses; the latter is transferred to Ototropis, as O. siamensis (Schindl.) H.Ohashi & K.Ohashi, comb. nov., based on morphological studies. No native species of Desmodium, therefore, occur in Asia or Australia. A new combination Grona reticulata (Champ. ex Benth.) H.Ohashi & K.Ohashi, comb. nov. is also proposed. Grona strigillosa was proved to be sister to all species of Grona examined so far, while G. heterophylla is sister to all Australian species of the genus. Desmodium of New Caledonia is enumerated in the current names including a new combination Oxytes deplanchei var. ovalifolia (Däniker) H.Ohashi & K.Ohashi, comb. nov. (Continued from J. Jpn. Bot. 95(5): 259–272, 2020)</p>
