It is readily distinguished from those species, and from all other species of Heteropterys, by the following combination of characters: small nearly glabrous leaves with large glands on the abaxial surface (not on the margin), epipetiolar stipules, umbels or corymbs of 4-6 flowers, well-developed peduncles with the bracteoles borne near the base, and tiny greenish petals.
The flowers are clustered racemes, corymbs, or panicles.
Inflorescences in sessile corymbs of axillary triads, 1 per axil, 4-5 cm in length, with 3-4 pairs of triads per inflorescence, axis of inflorescence angular, bracts ovate.
Species easily recognised by presentation of leaf blade obovate, emarginated and acute apex, as well as by inflorescences in corymbs of triads and an abundance of epicortical roots along the branches.
