Stem

Oak grain in the wood and a similar pattern in the inner blaze. Outer blaze often marked by white, granular stripes and pink-red, fibrous stripes, the latter exhibiting oak grain.

Leaves

Oak grain in the twigs. Leaf blades about 5-17 x 1.8-4 cm, greyish or silvery grey on the underside. Petioles about 0.7-2 cm long.

Flowers

Racemes about 4-8 cm long. Flowers paired, each sessile on a common peduncle. Common and individual floral bracts present at anthesis. Hypogynous glands three, linear-subulate. Ovary sessile, ovules 1 or 2.

Fruit

Fruits about 4-7 cm long. Seeds about 3-6 x 2-2.5 cm, wing marginal, about 5-10 mm wide. Embryo about 3 x 1.5 cm.

Seedlings

Cotyledons not emerging from the seed coat. Seed held in a vertical plane. First pair of leaves simple or lobed, the underside white or pale brown from dense, matted hairs. At the tenth leaf stage: leaf blade elongate-elliptic or elongate-obovate, apex acute, base attenuate, upper surface glabrous or with a few pale hairs especially along the midrib, undersurface densely clothed in pale brown, matted hairs; petiole, stem and terminal bud densely clothed in pale brown hairs. Seed germination time 48 to 94 days.

Distribution and Ecology

Endemic to NEQ. Altitudinal range from 180-1550 m. Usually grows in well developed upland and mountain rain forest, sometimes in stunted windswept forest on exposed ridges.
