Abstract
Richardia brasiliensis Gomes was found in agricultural land in Susan-ri, Seogwipo-si, Jeju-do. Richardia L. is closely related to Diodia L. in Korea, those are confirmed to features of calyx, collora and fruit. This species is similar to R. scabra L., but it differs morphologically from the letter in surface structure of mericarp. The mericarp of R. brasiliensis has line like kneel at the adaxial, whereas R. scabra has groove at the adaxial. R. brasiliensis is recorded for the first time in this study and a morphological description, distribution map, and photographs are presented.
