Species Description - Shrub or small tree 3-6 m tall, dichotomously branched, the twigs terete to angulate, with rather loose somewhat wrinkled bark, conspicuously lenticellate when young, sparsely lepidote, in part with short-stalked trichomes. Leaves 3(-4)-foliolate, the leaflets oblong to oblong-elliptic, rounded at apex, subcordate or asymmetrically cordate at base, the terminal 8-15 cm long, 4-8 cm wide, the basals 5-14 cm long, 2.3-9 cm wide, thick-coriaceous, strongly bullate, more or less glabrescently lepidote with scattered tiny reddish scales above and below, the margin entire to somewhat irregularly wavy, revolute; petiolules thick, the terminals 0.5-2 cm long, the basals 0.2-0.5 cm long, the petiole 1-3 cm long, lepidote with sessile and short-stalked peltate scales. Inflorescence 1-2 terminal long-pedicellate flowers, somewhat rufescently lepidote with sessile and short-stalked scales. Flower (only 1 seen) with calyx 6-10 mm long, 6-8 mm wide, very shallowly dentate, almost subtruncate, blackish lepidote, the corolla lilac (fide Britton), tubular-campanulate, 3 cm long, 0.8-0.9 cm wide at mouth, the tube 2.5 cm long, the lobes 0.5 cm long, glabrous outside, inside scurfy puberulous in floor, very sparsely long-pilose at level of stamen insertion; anthers held near middle of tube, divaricate, 3 mm long; ovary linear, strongly tetragonal, not obviously lepidote, 4 mm long, 1 mm wide; disk 1 mm long, 2 mm wide. Fruit linear-cylindric, attenuate at base and apex, 8-13 cm long; 7-11 mm wide, longitudinally striate-costate, sparsely lepidote, the surface minutely glandular-papillate, drying blackish, the valves thick-coriaceous, the calyx persistent; seeds thin, bialate, 4-5 mm long, 15-19 mm wide, sharply demarcated from seed body.
