Allocasuarina distyla, commonly known as scrub she-oak, is a shrub or small tree of the She-oak family Casuarinaceae endemic to New South Wales.
Description
This dioecious[2] shrub or small tree will typically grow to a height of 4 metres (13 ft) tall and is found in coastal areas of New south Wales and southern Queensland.[3] Its erect branchlets are up to 35 centimetres (14 in) long.[2] The ridges are angular to rounded and occasionally pubescent.[2] There are 6-8 teeth.[2] The spikes of male flowers are 1–5 centimetres (0.4–2.0 in) long with roughly 5 whorls of flowers per centimetre.[2] The cones are up to 12 millimetres (0.5 in) long and often have a sterile apex. The samara is a very dark brown.[2]
Taxonomy
The species was first described as Casuarina distyla by the botanist Étienne Pierre Ventenat in 1802 in the Description des Plantes Nouvelles et peu connues, cultivees dans le Jardin de J.M. Cels.[4][5] It was subsequently reclassified into the Allocasuarina genera by Lawrence Alexander Sidney Johnson in 1982 in a revision of the sheoaks, Notes on Casuarinaceae II., published in the Journal of the Adelaide Botanic Gardens.[6][7]
