The obovate (egg-shaped) to cuneate (wedge-shaped) seed is long. It is composed of the wedge-shaped seed body (containing the embryonic plant), measuring long by wide, and a papery wing. One side, termed the outer surface, is convex and pale greyish brown with irregular pits and the inner surface is dark brown and smooth. The seeds are separated by a sturdy dark brown seed separator roughly the same shape as the seeds with a depression where the seed body sits adjacent to it in the follicle. The first pair of leaves produced by seedlings, known as cotyledons, are wedge-shaped with a convex apical side and measure long by wide. Dark green in colour, they are faintly reticulated. The auricle at the base of the cotyledon leaf is pointed and measures long. The cotyledons sit on a short thick hypocotyl.
