Rock sheoak

(Allocasuarina huegeliana)



Rock sheoak is a dioecious tree that grows to a height of 4 to 10 metres (13 to 33 ft) The dark coloured bark is longitudinally fissured. It has sparse foliage that forms a rounded outline. Sometimes it branches at ground level, but usually has a bole of a few metres. As with other Allocasuarina species, the foliage consists of slender green branchlets informally referred to as "needles" but more correctly termed cladodes. These are segmented, and the true leaves are reduced to tiny teeth encircling each joint. Male trees have small brown flower spikes at the end of branchlets. Female trees bear small flowers on short branchlets of their own. The red to brown coloured flowers appear between My and January. Fertilised flowers develop egg-shaped cones about 1.5 to 3 centimetres (0.6 to 1.2 in) wide.
