  • Description

    Species Description - Deciduous tree 6-50 m, with plank buttresses to 3 m high, 1.7 m wide, 0.15 m thick. Leaves 4-11 × 2-4(-5.5) cm, chartaceous, elliptic-oblong to obovate or narrowly so, long-acuminate at apex, cuneate or attenuate-cuneate at base, sericeous when young, glabrous or nearly so except sparsely pubescent on main veins abaxially at maturity; domatia absent. Venation brochidodromous; midvein moderate, prominent; secondary veins (5-)7-12 pairs, moderately spaced to distant, diverging at widely acute angles, curved, prominent; intersecondary veins often present; tertiary veins randomly reticulate or sometimes weakly percurrent; higher order veins not distinct; areolation large, imperfect, scarcely prominent. Petiole 1.2-3.5 cm, usually glabrous, biglandular. Inflorescences 1.5-5.5 cm, simple, with all flowers bisexual; peduncle 0.5-2.8 cm, pubescent; rhachis 0.8-3.5 cm, subcapitate to moderately elongated, densely pubescent at flowering. Flowers pentamerous, 3-4.6 × 2-3.8 mm; lower hypanthium 1.5-2.2 mm, pubescent to densely so; upper hypanthium 0.8-1.5 mm, deeply cupuliform to deeply campanulate, pubescent to sparsely so; calyx lobes 0.7-1 mm, pubescent to sparsely so, revolute to erect; disk sparsely pilose; stamens 3-5 mm; style 3-4 mm, pilose proximally or almost to apex. Fruits few crowded on short rhachis, 1.6-3.2 × 3.3-7.8 cm, flattened, transversely oblong in side view, rounded to emarginate at apex, obtuse (often with concave basiscopic wing margin), truncate or slightly emarginate at base, glabrous and usually shiny; wings 2, fairly stiff, equal, 1.7-3.5 cm wide, rounded to very narrowly rounded laterally, to 4 cm long at longest point; body 0.4-0.7 cm wide, usually bulging on both faces. Reproductive biology. Flowers yellow-green, with slight scent, protogynous. Flowering October to March; fruiting October to June. The large-winged fruits seem well adapted for wind dispersal.
