Acacia rhodoxylon, also known as rosewood, ringy rosewood[1] or spear wattle,[2] is a tree belonging to the genus Acacia and the subgenus Juliflorae that is native to north eastern Australia.

Description

The tree typically grows to a height of 6 to 20 m (20 to 66 ft)

seed pods form that are slightly resinous. The pods age to a brown colour and have a narrowly oblong shape with a length of 3 to 7 cm (1.2 to 2.8 in) and a width of 5 to 9 mm (0.20 to 0.35 in) with longitudinally to obliquely arranged seeds inside. The shiny brown seeds have a widely elliptic shape with a length of 3.5 to 4.5 mm (0.14 to 0.18 in) and a small aril.[1]

Taxonomy

The species was first formally described by the botanist Joseph Maiden in 1920 as part of the work Notes on Acacias, with descriptions of new species as published in the Journal and Proceedings of the Royal Society of New South Wales. It was reclassified as Racosperma rhodoxylon in 1987 by Leslie Pedley and then transferred back to genus Acacia in 2001.[4]

Distribution

It is endemic along the east coast of central Queensland where it is found from around Eidsvold in the south to around Clermont in the north with another disjunct population near Mount Garnett further north where it is a part of Eucalyptus woodland communities.[1] It is often situated in hilly areas or undulating plains in the eastern part of the brigalow belt where it grows in skeletal sandy to clay soils with poor fertility where it is a part of open forest.[3]

Uses

The tree produces a quality and attractive timber but was historically used for fencing as the wood is

xylophones and for parts of violins as a substitute for ebony and in sporting goods requiring straight grained timber.[2]
