Acacia spinosissima is a shrub of the genus Acacia and the subgenus Phyllodineae native to south western Australia.
Description
[edit]The spreading or compact, intricately branched shrub typically grows to a height of 0.2 to 1.5 metres (0.7 to 4.9 ft).[1] It has striate and ribbed branches that are covered in a fine, white powdery coating with many short and spreading branchlets that are a quite spiny and often without phyllodes. Like most species it has phyllodes rather than true leaves. The ascending to erect phyllodes have a narrowly oblong shape and are usually straight or shallowly sigmoid. The green phyllodes usually have a length of 3 to 8 mm (0.12 to 0.31 in) and a width of 1 to 2 mm (0.039 to 0.079 in) with an obscure slightly raised midrib and no lateral nerves.[2] It blooms from August to September and produces yellow flowers.[1] The rudimentary inflorescences occur singly on racemes with an axis length of less than 0.5 mm (0.020 in)and have sperical flower-heads with a diameter of 3 to 3.5 mm (0.12 to 0.14 in) containing 7 to 23 bright lemon yellow coloured flowers. The thinly coriaceous seed pods that form after flowering rounded over the seeds with a length of up to 6 cm (2.4 in) and a width of 3 to 5 mm (0.12 to 0.20 in) and covered in a fine white powdery coating. The dark brown seeds within the pods have an oblong shape with a length of around 2.5 mm (0.098 in).[2]
Distribution
[edit]It is native to an area in the Wheatbelt region of Western Australia where it is commonly situated on undulating plains growing in gravelly sandy soils often over or around laterite[1] or loamy to clay soils. Its range extends from around Cadoux in the north to around Brookton in the south and as far east to around Lake King.[2]
