Shrubs, glabrous except the base of the internodes. Leaves glandless, the base of the short petiole 2-stipulate. Inflorescence a raceme (or in an extra-Mal. sp. a panicle). Pedicels sustained at the extreme base by a bract and bracteoles. Flowers actinomorphic, bisexual. Sepals glandless. Petals unguiculate, oblong, glabrous. Outer whorl of stamens longer than the inner one, anthers glabrous, each theca opening by a short apical slit. Styles 3, free, thin, somewhat shorter than the petals, often curved at the top. Often only 2 or 1 of the 3 mericarps developing; exocarp loosening from the endocarp, subcoriaceous, wings not developed except a relatively small, acute, dorsal crest.
