Milky exudate emerging from layers in the blaze and darkening cream or brownish on exposure. Dead bark layered.


Leaf blades about 4.5-9 x 2.5-4 cm. Numerous fine straight veins extending from the midrib to the margin but no other veins visible. Midrib slightly raised on the upper surface towards the apex but depressed towards the base. Petiole producing a small amount of milky exudate.


Petals (or inner tepals) about 7 mm long. Stamens about 95-140 per flower.


Fruits about 2.5-4.5 cm long. Endocarp about 1.2-3 mm thick. Fruits with shallow longitudinal grooves. When seed is cut, the cotyledons produce a yellow exudate.


At the tenth leaf stage: leaves elliptic to narrowly elliptic; more than 50 closely spaced, slightly curved, parallel veins run from the midrib to the leaf margin; terminal bud, petiole and stem of new growth clothed in short, tortuous, brown hairs. Seed germination time 49 to 158 days.
