Description

Tree 3-35 m, with large buttresses. Leaves chartaceous to subcoriaceous, narrowly elliptic to oblanceolate or narrowly obovate or oblong-obovate, rarely obovate, 4-30 x 1-10(-15) cm, apex obtuse to acute, abruptly acuminate or apiculate, base narrowly cuneate, densely rufous-pubescent to -tomentose all over when very young, pubescence varyingly wearing off with age but usually only sparsely pubescent above at flowering, still conspicuously and densely pubescent below at fruiting, especially on venous system; domatia absent; venation eucamptodromous to eucamptodromous-brochidodromous, with ends of secondary veins often forming a looped submarginal vein, midvein strong, very prominent, secondary veins 5-15 pairs, moderately spaced, arising at moderately acute angles, curved, strongly so at base, very prominent, intersecondary veins absent, tertiary veins percurrent or sometimes weakly so; higher order veins distinct; areolation well developed to imperfect, prominent, forming conspicuous raised reticulum; petiole 0.6-4.4 cm long, sparsely rufous-pubescent to tomentose, weakly biglandular, glands obscured by pubescence. Inflorescence 5-18 cm long, spicate; peduncle 2-4.2 cm, sparsely rufous-pubescent to rufous-tomentose; rhachis 3-14 cm, rufous-pubescent to -tomentoseFlowers 3.5-5 mm long; lower hypanthium 2-3 mm long, abruptly narrowed into long thin glabrous or sparsely pubescent neckca. as long as rufous-tomentose ovary-bearing part,upper hypanthium 1.5-2 x 2.5-4.5 mm, glabrous. Fruit densely rufous-tomentellous, 1.9-4.5 x 0.8-3 cm, oblong to elliptic or narrowly so in side view, terete to distinctly flattened and irregularly longitudinally ridged, apex rounded (outside Guyana more commonly apiculate) or shortly beaked with beak up to 6 mm long, base rounded to obtuse or very shortly pseudostipitate.

Distribution

Guianas present, Guyana present, Southern America: Colombia (Colombia present); Ecuador (Ecuador present); Peru (Peru present), Upper Amazon R. and Caqueta R present, northern Venezuela present, upper Orinoco R present, western part of the Rio Negro catchment present
Mainly in the western part of the Rio Negro catchment, extending N to the Upper Orinoco R., NE to Guyana and northern Venezuela, and W to the Upper Amazon R. and Caqueta R. in Colombia, Ecuador and Peru; only the type of B. pulcherrima and the cotyledon-bearing seedlings of the paratype are known from the Guianas (GU: 2).

Notes

The species has in most of its range oblanceolate leaves, and beaked fruits, but especially in Guyana and parts of Venezuela large-leaved specimens and beakless fruited specimens occur.
See note under B. megalophylla.
