Acacia richardsii is a shrub belonging to the genus Acacia and the subgenus Juliflorae that is endemic to north western Australia.
The bushy, rounded shrub typically grows to a height of 1.5 to 4 metres (5 to 13 ft). [1] It has glabrous and resin-ribbed branchlets that are angled towards the apices. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen slightly asymmetric phyllodes have a narrowly elliptic to oblong-elliptic shape and a length of 1.7 to 4 cm (0.67 to 1.57 in) and a width of 4.5 to 9 mm (0.18 to 0.35 in). The phyllodes are quite thin, obtuse and subglaucous and usually have two nerves per face with many barely noticeable minor nerves. [2] It blooms from March to August producing yellow flowers. [1] The simple inflorescences occur singly or in pairs in the axils on stalks that are 5 to 15 mm (0.20 to 0.59 in) in length supporting cylindrical flower-spikes with a length of 2 to 3 cm (0.79 to 1.18 in) and a width of 2 to 4 mm (0.079 to 0.157 in) packed with golden coloured flowers. Following flowering woody, red-brown seed pods form that have a narrowly oblong to linear shape and are narrowed at the base. The resinous pods are up to 8 cm (3.1 in) in length and 4 to 6 mm (0.16 to 0.24 in) wide with oblique longitudinal nerves. The shiny grey to brown seeds inside have an oblong shape with a length of around 4.5 mm (0.18 in) with a turbinate aril. [2]
It is native to a small area in the Kimberley region of Western Australia where it is situated on hills, creek beds and in rocky areas where it is found growing in sandstone based soils. [1] It has a limited range from around Kununurra extending eastwards into the top end of the Northern Territory as far as the Keep River National Park. [2]
