Allocasuarina humilis
Allocasuarina humilis, commonly known as dwarf sheoak, is a species of flowering plant in the family Casuarinaceae and is endemic to the south-west of Western Australia. It is an erect or spreading dioecious or monoecious shrub that has its leaves reduced to scales in whorls of five to seven, the mature fruiting cones 12–22 mm (0.47–0.87 in) long containing winged seeds (samaras) 5–6 mm (0.20–0.24 in) long.
Allocasuarina humilis adapts readily to cultivation. Versatile, it tolerates a wide range of soils, including those with some alkalinity, and prefers a sunny aspect. Tolerant of some exposure to coastal conditions, it is also planted for erosion control and as a windbreak. Unlike many Australian native plants, it is relatively tolerant of phosphates to some degree in cultivation.
Allocasuarina humilis is found across southwest Western Australia, from the Murchison River in the north, to the south coast, where it extends eastwards to Israelite Bay. It grows on sand, sand over laterite, gravel, or clay.
