Acacia pinguiculosa R.S.Cowan & Maslin

Acacia pinguiculosa is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to an area of south western Australia.

The shrub typically grows to a height of 0.3 to 1.5 metres (1 to 5 ft)[1] and is densely branched shrub that normally has a rounded habit. It has glabrous or sometimes hairy branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The glabrous and evergreen phyllodes are ascending to erect and have a linear or obovate to oblanceolate-oblong shape and are substraight to slightly incurved. The smooth fleshy phyllodes have a length of 10 to 30 mm (0.39 to 1.18 in) and a width of 1 to 7.5 mm (0.039 to 0.295 in) and have one to five nerves per face when flat orsix to eight nerves per face when more cylindrical.[2] It blooms from August to October and produces white-yellow flowers.[1]
Taxonomy

There are two recognised subspecies:

Acacia pinguiculosa subsp. pinguiculosa
Acacia pinguiculosa subsp. teretifolia
