Lateral leaflet blades about 6-13.5 x 2.8-5.2 cm, with about 15-36 lateral veins on each side of the midrib. Compound leaf axis somewhat flattened, margin angular or shortly winged towards the base.
Capsules not disintegrating following dehiscence, about 3-7 cm long, outer surface muricate. (Backs of the valves covered with short, broad, volcano-shaped humps.) Capsules normally present beneath mature trees, valves adhering by their bases and spreading like a flower.
Cotyledons obdeltoid to reniform, much wider than long, about 6-10 x 15-20 mm. Oil dots sparse, visible with a lens. At the tenth leaf stage: leaflet blades ovate, terminal leaflet attenuate at the base, lateral leaflets +/- sessile, midrib raised on the upper surface; oil dots numerous, visible to the naked eye; petiole and rhachis of compound leaf winged. Seed germination time 7 to 25 days.
