Glabrous except for the inflorescence, calyx and usually the corolla shortly brown-tomentose. Stems terete, enlarged at the nodes. Leaves opposite or rarely scattered ternate; petiole distinct, 0.8-2 cm long; lamina elliptical to ovate, usually widest in the middle (rarely below), 5-l0-(l5) by (3.5)-5-7-(12) cm, thick, attenuated or contracted at the base, more or less undulate at the margin when dry, rounded or obtuse at the apex; venation distinctly pennate on both sides with the midrib pro-minent on the under side. Inflorescences (as seen) solitary in the leaf axils; axis 2-3 mm thick, usually with 2 or more triad-bearing nodes crowded closely above the first; first internode (l0)-l5-20 mm long; second internode 4-10 mm long; third internode 1-4 mm long; triads 8-12 at the first node, 8-10 at the second node, (4)-6-8-(l0) at the third node; peduncles of the triads 5-8 mm long, 1-1.5 mm thick pedicels of the lateral flowers of the triads 2 mm long; bracts spreading, narrow, acute, 1 mm long. Calyx cylindrical, 3 mm long; limb truncate, 0.5 mm long. Corolla in the mature bud (25)-30-36 mm long; petals in the open flower 6, each with a deflexed spur inside (3)-6 mm above the base. Anthers 4-6 mm long, longer than the free parts of the filaments. Fruit urceolate, probably 8 mm long at maturity. (Fig. 1, r-t.) Chromosome Number.- n = 9 (Barlow and Wiens 1971).
