This species is closely related to Rhamnus erythroxylum but differs from the latter in having a prostrate, low habit; terminal buds small, never spinose; leaves small, oblanceolate or narrowly oblanceolate, with margin sparsely crenulate and apex rounded-obtuse; and stipules subulate, persistent.

Material of this species was not seen by the second author.

Flowers not seen. Drupes 1 or 2 at lower part of branchlets or in leaf axils of short shoots, obovoid-globose, 4-5 mm in diam., with shallow cup-shaped persistent calyx tube at base; fruiting pedicel 5-8 mm, glabrous, with 2(or 3) stones.
