Vernacular names

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

Description

The shrub typically grows to a height of 0.15 to 0.9 metres (0.5 to 3.0 ft)[1] but most usually around 0.3 m (1 ft 0 in) with flexuose and hairy branchlets. The primary leaf axis is obviously continuous and decurrent with the branchlet and have a length of 5 to 20 mm (0.20 to 0.79 in) and quite stout with two to four pairs of pinnae that are 2 to 12 mm (0.079 to 0.472 in) in length and two to six pairs of green to grey-green pinnules that have a narrowly oblong shape with a length of 2 to 7 mm (0.079 to 0.276 in) and a width of 1 to 1.5 mm (0.039 to 0.059 in).[2] It blooms from April to July and produces yellow flowers.[1] The simple inflorescences occur singly in the axils with large spherical flower-heads containing 22 to 35 densely packed golden flowers. The crustaceous, hairy seed pods that form later have a narrowly oblong shape with a length of 3 to 7 cm (1.2 to 2.8 in) and width of 6 to 7 mm (0.24 to 0.28 in) that contain mottled broadly elliptic seeds.[2]
Taxonomy

There are two recognised subspecies:

Acacia drewiana subsp. drewiana
Acacia drewiana subsp. minor

Distribution

It is native to an area in the Wheatbelt and Peel regions of Western Australia where it is commonly situated in low lying areas growing in gravelly or sandy soils.[1] The range of the plant extends from around Eneabba in the north down to around Mundijong in the south and out to around also Wongan Hills and Newdegate in the east.[2]
