Ridsdale (loc. cit.: 298-299) treated Benkara griffithii and B. forrestii as two different species, without commentary or a key, and synonymized Randia hainanensis under B. forrestii. W. C. Chen (in FRPS 71(1): 346. 1999) treated these names as synonyms of Oxyceros griffithii. However, B. forrestii and R. hainanensis were recognized as separate species by Tirvengadum (in herb.), and these appear morphologically distinct as outlined in the key to species above and thus are separated here. These are provisionally treated as endemic pending further study of this genus and specimens from surrounding countries.
