Sections of bark included in the wood.

Lateral veins forming loops well inside the blade margin. Oil dots visible with a lens. Young leaves and shoots purple. Leaf blades about 9-24 x 3-7.5 cm. Midrib raised on the upper surface.

Flowers

Calyx lobes rounded but rather indistinct. Petals variable in shape, quite large, about 8-10 mm long. Anthers +/- bilobed with a conspicuous gland in the emarginate apex.

Fruit

Fruits very variable, 3-lobed when perfectly developed, but frequently reduced to a two or 1-lobed condition. Calyx persistent at the base but insignificant. Fruits up to 20 x 30 mm. Seeds variable, often about 15-20 x 10-15 mm, testa thin and membranous. Cotyledons marked by oil glands.

Seedlings

Cotyledons +/- orbicular, about 10-17 x 20-24 mm, thick and fleshy, without venation. Usually 2 cataphylls just above the cotyledons. First true leaves elliptical, midrib raised on the upper surface. At the tenth leaf stage: leaf blade elliptic to obovate, apex acuminate, base cuneate, glabrous, veins about 15-25 each side of the midrib, midrib depressed on the upper surface; new growth dark bluish purple. Seed germination time 7 to 32 days.

Distribution and Ecology
