Poorly formed or multistemmed. Bark exudate very sticky.

Leaves

Leaf blades about 8-20 x 4.5-11.5 cm. Numerous fine veins extending from the midrib to the margin but no other veins visible. Midrib raised or depressed on the upper surface. Petioles and twigs produce a milky exudate which turns yellowish on exposure.

Flowers

Petals (or inner tepals) about 9-16 mm long. Stamens about 210-360 per flower.

Fruit

Fruits about 2.5-5 cm long. Endocarp about 0.7-1.2 mm thick.

Seedlings

At the tenth leaf stage: leaf blade elliptic; more than 50 closely spaced lateral veins run parallel from the midrib to the leaf margin; a few scattered stellate hairs on the petiole. Petiole grooved on the upper surface. Terminal bud densely hairy with pale brown tortuous hairs. Seed germination time 122 days.

Distribution and Ecology

Occurs in NT, CYP, NEQ, CEQ and southwards to coastal south-eastern Queensland. Altitudinal range at or close to sea level. A characteristic tree on beaches and rocky headlands often leaning out towards the sea, obviously wishing it was somewhere else. Widely distributed and cultivated throughout the tropics from West Africa to the Pacific islands as far east as Tahiti. One of the few beach trees which can withstand cyclonic winds.

Natural History & Notes

Fruits and leaves poisonous (Austin, D. F. 1998. Poisonous Plants of Southern Florida). The seeds of this species are a source of Calophyllum Oil which is reputed to have medicinal and healing properties.The seed oil was used in India as an application for skin diseases and as a liniment for rheumatism. Cribb (1981).

A highly ornamental tree.

Various parts of the tree have been widely employed in medicine in other countries. Leaves soaked in water give a scented lotion which has been used in places as far apart as Fiji and Malabar in India for bathing sore eyes.
