Buchenavia ochroprumna


Shrub or tree 3-12(-30) m. Leaves subcoriaceous, obovate to oblanceolate, 2-9.5 x 1-4.5 cm, apex rounded to retuse or rarely obtuse, base cuneate to narrowly decurrent-cuneate, appressed-pubescent when very young, becoming glabrous except often sparsely pubescent on midvein when mature; domatia present; venation brochidodromous, midvein moderate, slightly prominent, secondary veins 3-7 pairs, distant, originating at moderately acute angles, slightly curved, slightly prominent, intersecondary veins occasionally present, tertiary veins randomly reticulate; higher order veins not distinct; areolation incomplete; petiole 0.4-1.5 cm long, glabrous to sparsely appressed-pubescent, eglandular but base of leaf usually obscurely biglandular. Inflorescence 0.7-3.3 cm long, more or less capitate, with densely grouped flowers; peduncle 0.9-3 cm, rufous pubescent in flower, becoming subglabrous and much thicker in fruit; rhachis 0.2-0.5 cm. Flowers 3-4.5 mm long; lower hypanthium 2-2.5 mm long, abruptly narrowed to thin neck of 0.8-1.2 mm long, densely rufous-pubescent except sparsely so on neck,upper hypanthium 1.2-2 x 2.5-3.5 mm, subglabrous. Fruit densely tomentose, 18-30 x 7-17 mm, ovate in side view, terete or nearly so, usually irregularly and strongly ridged, apex abruptly narrowed to 0.4-1 cm long usually strongly curved beak, base rounded.

Flowering and fruiting


Wood for construction, boards.


The single specimen from French Guiana, Bena 1313, resembles most of those from Venezuela in having smooth fruits with a short beak. It is possible that they represent a new species, but some Venezuelan specimens have slightly ridged fruits and, as it has not been possible to link flowering or sterile material to the smooth-fruited plants, at present it is best to identify the latter with B. ochroprumnea.
