Genus

Characteristics

Trees. Leaves 1-pinnate; leaflets 2-5 pairs, diminishing in size downwards, terminal one largest, beneath glabrous or tomentose with stellate hairs, with few scattered, larger, flat, spot-like glands and small hairy domatia in the nerve-axils. Thyrses axillary or terminal, densely or laxly tomentose, or at least almost always with (sometimes) small and appressed stellate hairs. Calyx tubular or campanulate, unequally 2-5-lobed, with few to many warty or prominent glands in the upper half. Corolla with a fairly large basal tube, rather suddenly campanulate-funnel-shaped widened to the mouth; lobes undulate to crenate. Stamens 4, didynamous; 5th rudimentary; anthers divaricate. Disk annular. Ovary elongate, with 2 marginal placentas in each cell; ovules. Capsule long, linear, terete, twisted or straight, pendent, smooth or ribbed; septum flat, smooth, not rarely glossy, thickish. Seeds numerous, rather rectangular, the wings rather narrow; insertion punctiform.
More
Trees. Leaves 1-pinnately compound; leaflets 2-5(or 6) pairs. Inflorescences cymose, terminal or axillary, pubescent. Calyx tubular or campanulate, usually 2-5-lobed, subzygomorphic or regular, persistent. Corolla funnelform or campanulate; lobes 5, subrounded, sinuate or crenate. Stamens 4, didynamous; anthers 2-celled, slightly divergent, included; staminodes small. Disc annular, occasionally dentate. Ovary terete, glabrous or pubescent, 2-locular; ovules numerous, in 2 rows. Capsule dehiscing loculicidally, 4-angular; valves thin leathery; septum thick, smooth, vertical with fruiting valve. Seeds in 2 rows, numerous, nearly square, narrowly membranous winged at both ends.
Leaves caducous, imparipinnate, opposite, Flowers large, in short few-flowered racemes or solitary, borne praecociously and in axils of fallen leaves.
Calyx campanulate irregularly lobed, opening just before the corolla anthesis.

Usage

Uses. All Indo-Malesian species seem to be good timber trees and of the Indo-Chinese species it is said that the timber is good for all purposes and not attacked by termites. They may already flower and fruit at an early age.
