Acacia incurva

Acacia incurva is a shrub belonging to the genus Acacia. It is native to the South West region of Western Australia.

The shrub has a low, multi-stemmed, erect or prostrate and spinescent habit. It typically grows to a height of 0.2 to 0.5 m. The stems are angled and the phyllodes are continuous with branchlets with the free portion of the phyllodes having a linear to linear-lanceolate shape with a length of 10 to 50 mm and a width of 1 to 2 mm. It blooms in the winter months between July and September producing spherical yellow inflorescences. Each simple globular inflorescence has sessile heads and contains between six and eleven bright yellow flowers. Later it will form terete seed pods that are up to 7 cm in length with a diameter of around 2 mm. Each pod is crustaceous, reddish in colour with longitudinale nerves. The species was first formally described by the botanist George Bentham in 1842 as part of William Jackson Hooker's work Notes on Mimoseae, with a synopsis of species in the London Journal of Botany. Synonyms for this species include; Racosperma incurvum, Acacia incurva var. brachyptera, Acacia incurva var. incurva and Acacia brachyptera. The species is found in swamps, winter-wet areas and clay flats where it grows in sandy, clay or lateritic soils.
