Ramosmania (from Rodrigues Island, Mauritius), recently described by Tirvengadum & Verdcourt as a genus of uncertain position, is here shown to belong to the tribe Hypobathreae (subtr. Hypobathrinae). It is related to Morindopsis Hook. f. Two other rubiaceous genera previously placed in the tribe Gardenieae, viz. Para‐genipa Baillon, from the Seychelles, and Nargedia Beddome, from Sri Lanka, are also shown to belong to the tribe Hypobathreae. Paragenipa cervorum Baillon being conspecific with Randia lancifolia , (Boj. ex Bak.) Hemsl. the new combination Paragenipa lancifolia is made. From the anatomical point of view, Paragenipa is interesting on account of its remarkable seed‐coat (exotesta with several layers of fibres), unusual in most Rubiaceae. Nargedia is the first representative of the subtribe Lamprothamninae outside Africa.
