Tree 5-25 m. high, the trunk up to 90 cm. in diam., the young branches to-mentellous and sparsely pilose, the pubescence of stellate hairs. Leaves crowded toward the end of the branchlets, simple, the petiole rounded, 2.5-7 cm. long, tomentellous and sparsely pilose, the blade ovate-oblong to elliptic-oblong, obtuse, truncate or slightly cordate at the base. abruptly acuminate-apiculate at the apex, 9.5-22.5 cm. long and 5.5-12.5 cm. wide, subcoriaceous, the margins entire to some-what undulate, the upper surface glabrous or nearly so and with impressed vena-tion, the lower surface sparsely pubescent and with prominent venation, 5-nerved at the base. Inflorescences axillary, paniculate, the axes villous. Flowers her-maphrodite (or pistillate only?) or staminate, the pedicel 4-10 mm. long; calyx deeply (4-)5-lobate, 9-12 mm. long, the lobes linear-lanceolate, acute, 6.5-10 mm. long and 2-3 mm. wide, the outer surface puberulous-villous, the inner surface provided from the base to the middle of the lobes with a tiny appendage, the appendage villous especially near the base and cucullate at the apex, puberulous-villous above the appendage; gonophore of the staminate floxvers filiform, arcuate, inflexed, glabrous except the much-thickened papillate base, 5.5-6 mm. long, the staminal tube pendulous, urceolate, very short, glabrous, the anthers 10, ca. 0.5 mm. long, the rudimentar ovary rather obsolete; gonophore of the hermaphrodite flowers (according to Pittier, Contr. U. S. Nat. Herb. 13: 450, fig. 78. 1911) sub-erect, glabrous except the much-thickened papillate base and ca. 5 mm. long, the staminal tube cupuliform, ca. 0.8 mm. long and 2 mm. wide, glabrous, the anthers 10, the ovary depressed-globose, 5-sulcate, tomentellous, 5-locular, the styles re-flexed, ca. 1.8 mm. long and tomentellous, the stigma indistinctly 5-lobulate. Follicles subglobose, obliquely apiculate, ca. 7(10-15) cm. in diam., shortly to- mentellous; seeds ellipsoid-oblong, ca. 1.6 cm. long and 0.7 cm. thick, the testa covered with fine sharp hairs ca. 1.5-2 mm. long.
