 note = {We explored Peninsular Malaysia to collect wild legumes belonging to the subgenus Ceratotropis of the genus Vigna. Wild Ceratotropis species are considered to be useful gene (s) source for the breeding of mungbean (Vigna radiata), black gram (V. mungo), moth bean (V. aconitifolia), azuki bean (V. angularis) and rice bean (V. umbellata). The exploration was conducted from February 8 to 19, 1993. A total of 105 samples were collected from 27 different sites in Peninsular Malaysia. The collected samples consisted of three wild Ceratoropis species, i. e., Vigna trinervia (98 samples), V. reflexo-pilosa (6 samples) and V. minima (1 sample). Vigna trinervia distributed most commonly throughout the route of exploration. V. reflexo-pilosa was found at two different sites. Habitat of V. reflexo-pilosa was similar to that of V. trinervia. They were usually found on road side or at the edge of plantation where the habitat are occasionally disturbed by clearing or burning by a human being. V. minima was found at only one site. This site was at the edge of natural forest and had wet soil condition. The pods of V. trinervia were usually attacked by stink bugs and the seeds were shriveled siverely. However, there were several sites where V. trinervia had well developed seeds. Only at the sites where V. trinervia had well developed seeds, we found red ants (Oecophylla samaragdina) or black ants (Crematogaster sp.) collecting extra-floral nectars from V. trinervia. These ants were aggressive and were considered to protect pods from the attack by stink bugs. By the exploration, it was clarified that wild Ceratotropis species were widely distributed in Peninsular Malaysia. Especially, V. trinervia was revealed to be very common in Peninsular Malaysia.},
