Description

Tree up to 30 m; young branches orangeish-brown, ferrugineous-velutinous to glabrous, striations narrow, multiple; older branches light brown to black, glabrescent, patchy, sometimes with a thin white coating, striate or small fissured; lenticels numerous to few. Petiole 4.8-12(-20) cm long, terete to laterally compressed, 2-5.5 mm in diam. at base, velutinous or rarely glabrescent with rows of pilose (villous) hairs; leaf rhachis 6-21.7(-45) cm long, terminal appendix 1.5-5 mm long, ca. 1 mm broad, usually absent; leaflets subsessile to short-petiolate, petiolules up to 1.3 cm long, 2.25-2.5 mm in diam. at base; leaflets 3-4(-5) pairs, opposite to almost alternate, drying olive green to black, coriaceous to subcoriaceous, occasionally chartaceous, glabrous above, glabrous to very sparsely white-puberulent beneath, indument if present short and closely appressed and concentrated on venation, frequently asymmetrical, elliptic to broadly elliptic, less commonly obovate or ovate, usually curving; basal pair of leaflets similar to terminal ones, 6.5-14.5(-22.7) x 3.2-5.5(-7.5) cm; other leaflets 10.8-13(-24.5) x 4.3-7.6 cm; base equal to rarely weakly oblique, decurrent, apex acute to obtuse, less frequently rounded, truncate or retuse, especially in basal leaflets, sometimes broadly mucronate, margin entire to denticulate, commonly undulate; venation cladodromous to brochidodromous, with 4-7 pairs of secondary veins, midvein prominent throughout, reaching apex, secondaries straight, faintly prominent, higher order venation always conspicuous beneath, in coriaceous leaves obscure above. Inflorescence moderately lax, occasionally branched, axillary, 2.1-3 cm in diam.; peduncle 2.9-9.4 cm long, 1.5-2 mm in diam.; floral rhachis 12.4-16.5 cm long, ferrugineous to grey, densely appressed-puberulent; bracteoles heteromorphic, basal ones linear, unusually long, up to 4 mm long, light ferrugineous-hirsute, superior ones smaller, broadly triangular, 0.5-1.25 mm long, not recurved; flower-pair peduncle 1-4 mm long, ferrugineous-velutinous; pedicels 1.5-5 mm long. Flower buds 2.5-3 mm broad at apex, rostrate, beak up to 1 mm long, ca. 0.8-1 mm broad at midlength, essentially erect, ferrugineous-villous to sparsely soFlowers 7-11 mm long, all tepals recurving at anthesis, rarely one remaining erect; tepals 0.5-0.75 mm across at midlength, keeled or not; anthers subsessile, 1-1.2 mm long; hypogynous glands fused into a quadrangle or ring 0.5-0.75 mm high and 1-1.25 mm across; ovary 1.5-2 mm long, narrow, cylindrical-pyriform, square in cross-section, rufous-hirsute to short-pilose, more or less appressed. Infructescence 13.1-14 cm long; fruit pedicel 8-9 mm long, ca. 2 mm thick. Young fruit ovoid, 15-16 x 10-11 mm.
