Acacia vincentii

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

Description
The shrub typically grows to a height of 3 m and has long, arching branches with cylindrical and hairy branchlets that have persistent bristle-like stipules with a length of 2 to 2.5 mm. Like most species of Acacia it has phyllodes rather than true leaves. The ascending to erect, thinly leathery and evergreen phyllodes have an inequilaterally oblong-oblanceolate shape with rounded upper margin. The hairy phyllodes have a length of 4.5 to 5 mm and a width of 1.5 to 2 mm and two or three slightly raised nerves. It blooms in August and produces yellow flowers. The simple inflorescences occur singly in the axils and have obloid shaped flower-heads with a diameter of 5.5 mm and contain 41 yellow coloured flowers. The hairy and crustaceous seed pods have a narrowly oblong shape and are curved with a length of up to 5.5 cm and a width of 5 to 10 mm and contain shiny black seeds.

Distribution
It is native to an area in the Kimberley region of Western Australia where it is commonly situated on sandstone plateaux in shallow sandy soils. It has a limited range and is confined to the Edkins Range.
