Usually flowers and fruits as a shrub about 2 m tall.


Stipules hairy, about 3-5 mm long, fused at the base and encircling the twigs, each stipule ending in two aristate tips. Leaf blades about 4-8 x 1-2.5 cm. Lateral veins forming loops inside the blade margin.


Flowers +/- sessile. Calyx pubescent on the outer surface, tube (hypanthium) about 1 mm long, lobes 0.2 mm long. Corolla pubescent on the outer surface, tube about 1 mm long, lobes about 2 mm long, tips inflexed or hooked. Corolla tube hairy about the throat on the inner surface. Anthers about 1 mm long. Style inserted in a bilobed disk at the apex of the ovary.


Fruit globose or cylindric, about 10-12 mm diam, calyx lobes small but persistent at the apex. "Seeds" (endocarp) longitudinally ribbed on the convex side, smooth on the flat side. Endosperm +/- ruminate. Embryo small, about 1.5-2 mm long, cotyledons slightly wider than the radicle.


Cotyledons stipulate, cordate to +/- orbicular, about 7-9 x 6-8 mm. First pair of leaves opposite and stipulate. At the tenth leaf stage: leaf blade puberulent, narrowly elliptic or narrowly lanceolate, stipules about 4-6 mm long, each stipule ending in two aristate tips. Seed germination time 101 to 187 days.
