A small tree seldom exceeding 30 cm dbh.


Stipules about 4-8 mm long and about 4 mm wide at the base, but tapering to a fine point at the apex. Leaf blades about 9-21 x 3.5-9.5 cm. Petiole shallowly channelled on the upper surface. A horizontal line of hairs usually visible on the twigs just above each stipular scar.


Calyx lobes very small, less than 0.5 mm long, calyx tube minutely pubescent. Corolla tube about 5-7 mm long, lobes about 4.5-6 mm long. Corolla glabrous outside, but tube hairy near the apex on the inner surface. Anthers completely exserted beyond the corolla tube at anthesis. Style pubescent in the upper half.


Fruits globular, about 8-10 mm diam. Cotyledons flat, +/- orbicular, base cordate.


Cotyledons orbicular, broadly ovate or bluntly triangular, about 13-20 mm long, 3-5 veins radiate from the petiole. Cotyledonary blade elliptic, apex acute, glabrous on the upper surface. Stipules interpetiolar, triangular, about 4-5 mm long, keel drawn out into a fine point at the apex. Seed germination time 42 to 69 days.
