Climbers, sometimes forming large lianas. Leaves opposite; Inflorescence a cyme; Sepals 4, outer and inner pair sometimes slightly different sizes, with many small colleters at base inside. Stamens completely included in the tube, free from the style head; Ovary syncarpous, bilocular, with 2 or 3 ovules in each cell; Fruit a berry, pulpy inside. Seeds simple, with a membranous testa.

4 species in Southern Thailand, Sumatra, Peninsular Malaysia and Borneo.
Several species were described by , which Leeuwenberg (2003) has placed in synonymy of existing species of Leuconotis. Leeuwenberg noted that he had not seen the types which he presumed were in BO. I have not been able to find these types in BO and given that many of Boerlage’s other species, for which we do still have types, were described in the wrong genera it is perhaps risky to assign these Leuconotis species and I have included them only in a list of insufficiently known taxa at the end of this flora account.
