Trees or shrubs to S m tall, the twigs pubescent or glabrescent, ultimately angular, the nodes well spaced below, somewhat crowded terminally. Leaves oblong rotund, 11.5-38.0 cm long, 8-26 cm wide, rounded or obtuse at the apex, not acuminate, basally rounded, obtuse or truncate, the costa plane or immersed above, prominent beneath, to 0.35 cm wide, the lateral veins 8-11, widely arcuate, strict, prominent beneath, the intervenal areas spreading reticulate, coriaceous, drying dark brown above, bullate, glabrescent to golden villosulose above, golden appressed pilose beneath; petioles 2.0-4.5 cm long, rigid, lignose, golden villo-sulose; stipules not seen. Inflorescences terminal, solitary, golden villosulose, cymose paniculate, to 14 cm long, to 10 cm wide, the peduncles 0.5-4.5 cm long, the lowermost branches opposite, 1-2 cm long, angular, usually with 2 pairs of opposite, strongly ascending, superior branches. Flowers sessile or subsessile; hypanthium subturbinate, ca. 1 cm long, densely golden villosulose, the calycine cup cupuliform, ca. 3 mm long, coriaceous, pubescent outside, glabrous within, the lobes 5, 1-2 mm long, oblong to rotund, obtuse or rounded, coriaceous, golden villosulose on margins and outside, glabrous within, drying much darker than the hypanthium; corolla white, the tube narrowly cylindrical, 3.5-5.0 cm long, 0.35-0.50 cm wide, densely villosulose outside, the hairs occasionally tuft-ed, glabrous but rugulose within, coriaceous, the lobes narrowly oblong, 2.0-2.5 cm long, crassate, carnose and rugulose within; stamens 5, the anthers with tips barely exserted from tube, narrowly oblong, ca. 7 mm long, the filaments ca. 2.5 mm long, glabrous, somewhat geniculate at point of attachment, attached ca. 1 cm below the mouth; style ca. 25 mm long, plano compressed, villose, the stig-matic lobes 2, ca. 1.8 mm long. Fruits with pedicels to 1.5 cm long, narrowly oblong, to 9 cm long, the valves at dehiscence to 2 cm wide, obtuse or rounded at the apex, cuneate at the base, smooth, rugulose, glabrescent at maturity, with a few slender longitudinal prominulous lines outside, the calycine cup persistent in unopened fruit, finally deciduous in open fruit.
