Acacia erinacea , también conocida como acacia espinosa , [1] es un arbusto perteneciente al género Acacia y al subgénero Phyllodineae que es nativo de Australia Occidental.
The rigid and prickly shrub typically grows to a height of 0.1 to 1.5 metres (0.3 to 4.9 ft).[2] It has branches that divide into short, divaricate, whitish, finely ribbed and spinose branchlets. The new shoots are red to red-brown in colour. The ascending to erect grey-green phyllodes have an oblong to elliptic to oblanceolate shape with a length of 5 to 12 mm (0.20 to 0.47 in) and a width of 2 to 4 mm (0.079 to 0.157 in).[3] It blooms from June to November and produces yellow flowers.[2] Each inflorescence has spherical flower heads containing 12 to 22 golden flowers. After flowering the seed pods form that have an oblong shape and are slightly biconvex. Each pod is 1 to 3 cm (0.39 to 1.18 in) in length and 7 to 10 mm (0.28 to 0.39 in) wide containing dark brown oblong ovate shaped seeds.[3]
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 as published in the London Journal of Botany 1. It was reclassified as Racosperma eriocladum in 2003 by Leslie Pedley then transferred back to the genus Acacia in 2006.[1] The type specimen was collected by James Drummond.[3]
Es endémica de un área en las regiones del Medio Oeste , Goldfields-Esperance , Wheatbelt y Great Southern de Australia Occidental, donde crece en la mayoría de los tipos de suelo, especialmente en aquellos con alto contenido de arcilla. [2] El arbusto se encuentra tan al norte como Kalbarri y tan al sur como Broomehill y hasta Eucla en el este en colinas y tierras planas donde a menudo forma parte de comunidades de matorrales de bosques de eucaliptos , mallee y llanuras de arena.
