Trochocarpa laurina is an Australian shrub or small tree. It occurs from near Bermagui (36° S) in southern coastal New South Wales to the Wet Tropics in Queensland. It grows at the summit of Mount Bellenden Ker,[citation needed] which has an average annual rainfall of 8312 mm. The minimum annual rainfall requirement is 1200 mm.[1]

The habitat is rainforest of various types and wet sclerophyll forest. In August 1990, the then-largest known specimen was documented in the Sydney suburb of Eastwood; it stood 13.4 m (44 ft) tall.[2] Common names include tree heath, axebreaker, sandberry, wheel-fruit, waddy wood, laurel heath and turkey bush.

Description[edit]

A small tree or shrub with a corky trunk, and heavy low branches. The crooked trunk can be up to 45 cm in diameter, slightly flanged at the base. Often seen around 4 metres tall.[3]

Leaves alternate, grouped at the ends of the branchlets. Not toothed, elliptic, 5 to 7 cm long, pointed at the tip. Glossy green both sides, paler beneath. Five to seven parallel and longitudinal veins on the leaf. New leaves brilliant dark pink or red.[3]

White flowers single or on spikes, 2 to 3 cm long form in all months, mostly seen in June and July. The fruit is a small flattened drupe; purple to black in colour, maturing from March to October. Within the aril of the drupe is a ten ribbed bony endocarp, each of the ten cells within contains a seed. Seed germination is very slow and difficult, taking between two and four years for the first seedling to appear. Fruit eaten by Lewin's honeyeater and the pied currawong.[3]

Ecology and uses[edit]

Host to the parasitic mistletoe Korthasella rubra ("korthal mistletoe"). Host tree for epiphytes including bird's-nest fern and elk horn fern. Used by Aboriginal Australians for waddies.[1] Timber is hard with an attractive grain.
