Acacia semitrullata is a shrub of the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.
The slender, erect and pungent shrub typically grows to a height of 0.2 to 0.7 metres (0.7 to 2.3 ft).[1] It has orange-brown coloured branches and hairy branchlets with narrowly triangular stipules that are 1 to 2 mm (0.039 to 0.079 in) in length that are incurved. Like most species of Acacia it has phyllodes rather than true leaves. The patent and occasionally reflexed, rigid, greem phyllodes have a narrowly semi-trullate shape with a length of 5 to 10 mm (0.20 to 0.39 in) and a width of 1.3 to 2 mm (0.051 to 0.079 in) with a prominent midrib.[2] It blooms from May to October and produces cream-white flowers.[1]
Taxonomy
The species was first formally described by the botanist Bruce Maslin in 1978 as part of the work Studies in the genus Acacia. A revision of the Uninerves - Triangulares in the journal Nuytsia. It was reclassified as Racosperma semitrullatum by Leslie Pedley in 2003 then transferred back to genus Acacia in 2006.[3]
