A taxonomic and phytogeographic account of Desmodium and its related genera in Malesia Malesia is presented as a precursory of treatment these genera for the Fl ora Malesiana. Sixty-four Sixty-four species in 13 genera 訂 'e recognized: Aphyllodium (3 spp よ Codariocalyx (3 spp よDendrolobium (8 spp よDesmodiastrum (1 sp よDesmodium (35 spp. of which 27 native native to Malesia and 8 introduced from America) ， Hanslia (2 spp よHegnera (l sp よ Hylodesmum (4 spp よ Monarthrocarpus (1 sp よ Ohwia (1 sp よ Phyllodium (3 spp よ Tadehagi Tadehagi (l sp.) ， and Trifidacanthus (1 sp.). They 訂 e enumerated with keys to genera ， species species and infraspecific taxa ，selected synonyms and bibliography related to the Malesian Malesian flora ，representative specimens ， and distribution. Of the 56 species native to Malesia Malesia eight (14 %)訂 e endemic to the region; 29 (52 %)訂 e distributed in Malesia and continental continental Asia but not in Australia; 11 (20 %) are common in Malesia and Australia but not not in continental Asia; and eight (14 %) are found in all these areas. Based on the dis- tribution tribution analysis ，a differentiation pattem of the species in these genera in Malesia is presumed. presumed. This This paper is divided into two parts. Aphyllodium ，Codariocalyx ，Dendrolobium ， Desmodiastrum ， and Desmodium are treated in the first p訂t. Following new combina- tions tions or new status are proposed: Codarioc α lyx microphyllus (Thunb.) H. Ohashi ， Desmodiastrum parviflorum (Dalz.) H. Ohashi ，Desmodium nemorosum F. Muell. ex Benth. Benth. subsp. whitfordii (Schind l.) H. Ohashi ， and Desmodium strigillosum Schind l. subsp. subsp. celebicum (Schind l.) H. Ohashi.
