Ancestral Casuarinaceae pollen records have provided details of early forms of the family back to 50 millions years ago, enabling sheoak genealogy to be traced across the ancient Gondwanan landscape.
Slender sheoak often only 50cm high in coastal heaths, but small tree on the Central Plateau.
Male and female flowers often on separate plants.
Branchlets jointed, slender and minutely ridged, blue-green. Leaves in whorls, visible as scale-like
teeth at the joints, their bases fused.
Male flowers in orange-brown spikes at ends of branchlets.
Young female cone stalked, red with long styles, mature cone grey, oblong, top often pointed,
individual scales below each carpel quite conspicuous.
Flowering mainly in winter but also other seasons.
Habitat/Distribution: Endemic. Widespread throughout the east of Tasmania and Bass Strait Islands. Tolerates a wide range of soils from sand to clay, coastal heaths to subalpine scrub.
Cultivation: Good windbreak, tolerating dry conditions as well as frost and some shade. Prone to borer. Propagate from seed.
