Description

The dense rounded shrub typically grows to a height of 0.5 to 2.0 metres (1.6 to 6.6 ft)[2] It has shortly haired branclets with raised leaf bases. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen and crowded to scattered phyllodes are straight and slender with a length of 5 to 8 mm (0.20 to 0.31 in) and a width of 0.3 to 0.4 mm (0.012 to 0.016 in) with no discernible nerves.[3] It produces simple inflorescences with yellow flowers between July[2] and October.[1]

Taxonomy

The species was first formally described by the botanist Bruce Maslin in 1999 as part of the work Acacia miscellany. The taxonomy of fifty-five species of Acacia, primarily Western Australian, in section Phyllodineae (Leguminosae: Mimosoideae) as published in the journal Nuytsia. It was reclassified as Racosperma leptaleum by Leslie Pedley in 2003 then transferred back to genus Acacia in 2006.[4]

Distribution

It is native to an area in the Great Southern region of Western Australia where it is often situated along drainage lines and on undulating plains growing in sandy to loamy soils.[2] It is found in only a small area around Chinocup, close to Nyabing where it is quite common locally common especially adjacent to salt lakes and is estimated to have a total population of approximately 550 plants, it is thought to have been far more widespread prior to clearing for agriculture.[1]
