Tree to 15 m high and c. 38 cm in diam. Leaves 1- or 2-foliolate, when 2 then often not opposite, very shortly petioled; petiole and rachis up to c. 10 mm long, prolonged beyond the upper petiolule into a subulate tip c. 2 mm long. Stipules intrapetiolar, c. 3.5 mm long, caducous. Inflorescences axillary or sometimes terminal, up to c. 11( — 16) cm long, glabrous, rather loosely flowered; bracts of the peduncle triangular, or 3-lobed with the central lobe relobed and bristle-like, up to c. 5 mm long, glabrous except ciliate at the margins; bracteoles often at the lower half or at the base of the pedicel, minute, triangular, 0.75-1 mm long; pedicels 2-4(-9) mm, articulate at the base, glabrous. Flowers glabrous outside except ciliate at the margin of the calyx lobes, white or yellowish white. Stamens 10; filaments 4-6 mm (or longer); anthers c. 0.75 mm long.

Crudia subsimplicifolia is closely allied to C. reticulata. It can be easily recognized by the 1- or 2- foliolate leaves, usually glabrous on both surfaces, nerves flat above, and inflorescences with glabrous peduncles, rachides, pedicels and flowers (except shortly ciliate at the calyx margins).
