Seldom exceeding 30 cm dbh. Sapwood surface often corrugated.


Leaf blades about 3-6.5 x 2-3 cm. Lateral veins forming loops well inside the blade margin. Terminal buds and very young shoots clothed in pale brown hairs. Small oil dots visible with a lens. Midrib raised on the upper surface and petiole channelled on the upper surface.


Inflorescences shorter than the leaves, often not much longer than the petioles. Flowers about 1-2 mm diam.


Capsule 3-horned, about 6-9 mm diam., completely disintegrating when the seeds are shed, leaving only the central axis still attached to the tree.


Cotyledons almost orbicular, about 7-9 mm diam. At the tenth leaf stage: leaf blade narrowly elliptic, margin serrate; petiole hairy. Seed germination time 27 to 42 days.
