Within the Wet Tropics region rusty carabeen trees grow only in the restricted areas of luxuriant, mature, mountain rainforest on the Mount Carbine Tableland between Black Mountain and Mt Spurgeon, and on Mt Lewis.[2][3] There they grow on soils built from granite parent materials.[2]
Description
Mature trees have fluted trunks and grow to 30 m (100 ft) tall. The leaves occur opposite each other, when new have dense rusty hairs all over them which persist on the underside and the top midrib, and measure 7.5 cm–16 cm × 3.5 cm–7.5 cm (3.0 in–6.3 in × 1.4 in–3.0 in). Near the ends of new growing branches grow racemes of pink flowers, each approximately 20 mm (0.8 in) long. They produce bunches of yellow–orange–red, oval shaped fruits measuring 30 mm–45 mm × 18 mm–28 mm (1.18 in–1.77 in × 0.71 in–1.10 in).[2][4] Their fibrous ripe flesh smells like ripe watermelon.[3]
Although not yet well known, the trees have some popularity in cultivation, for example in Brisbane.[citation needed]
