Staminal tube 2/3–3/4 the length of the corolla, subglobose, with a wide aperture 0.4–0.5 mm across, entire; anthers 5, ovoid, 1/2–2/3 length of the staminal tube, inserted 1/3–1/2 the way up the tube and protruding through the aperture. Fruits 5.5–6 cm long and 3.5–4 cm in diam., subglobose or pyriform, dull green, grey, brown or blackish-purple, becoming yellow or orange when ripe; pericarp woody, 1 mm thick, densely covered with scales like those on the twigs on the outside; stalk stout, up to 2 cm long and 1 cm wide.

The leaves of Aglaia crassinervia resemble A. rufinervis, but there are fewer leaflets and the indumentum is of peltate scales with a fimbriate margin rather than stellate hairs or scales. The length of the fimbriate margin on the peltate scales varies. When the scales have a long fimbriate margin, it is sometimes difficult to distinguish A. crassinervia from A. sexipetala. That species has numerous stellate scales on the lower leaflet surface and some compact stellate hairs interspersed; the latter are absent in A. crassinervia.
