A small tree not exceeding 30 cm dbh.
Twigs and petioles produce a milky exudate. Leaves in whorls of four or five. Leaf blades variable in size, up to 5 x 2.5 cm, petioles about 0.3-0.7 cm long. Lateral veins about 10-20 on each side of the midrib, but very difficult to distinguish on fresh leaves. Margins of leaf blades often recurved and ending in a sharp point at the apex.
Numerous bracts present at the base of each flower. Flowers about 5-10 mm diam. Sepals about 2.2-3 mm long, glabrous except for the ciliate margins. Corolla tube about 5-8 mm long, outer surface glabrous, inner surface pubescent about the anthers, lobes about 3.5-5.5 mm long with the left margins overlapping. Corolla glabrous on the outer surface. Anthers about 1.2-1.5 x 0.4-0.5 mm, filaments about 0.1 mm long.
Fruits often moniliform (beaded), each bead about 7-8 x 4-6 mm.
