Trees. Leaves opposite and decussate, imparipinnate, trifoliolate or rarely unifoliolate; Stipules interpetiolar, one pair per node, reniform or bilobed, caducous. Inflorescence axillary, corymbiform, many-flowered, branching at proximal nodes opposite, then subopposite and then alternate, most distal floral subunits cymose, peduncle 1/3- 1/2 of total length. Flowers 5-6-merous (except for gynoecium), petaliferous, pedicellate, bisexual but generally markedly protandrous; Sepals valvate, ovate to triangular, attached to hypanthium at their greatest width, not connate, glabrous above. Petals ovate to oblong, longer than calyx, not fugaceous. Stamens twice as many as sepals, with filaments thin, subulate, glabrous and anthers broadly cordate, the connective shortly extended. Ovary syncarpous, superior, 2-carpellate, hairy, each cell bearing a glabrous, cylindrical style; Fruit dehiscent, a septicidal capsule, the valves 2, boat-shaped, coriaceous in central part and thin at the edges (lateral extensions of the endocarp), the margins (placentae) of each valve remaining attached to the endocarp; Seeds numerous, small, elongate, with narrow, subequal terminal wings.
