Hakea horrida is a shrub in the family Proteaceae and is endemic to an area in the Wheatbelt, Great Southern and Goldfields-Esperance regions of Western Australia. It is a small dense shrub, extremely prickly with large creamy white scented flowers.
The intricately branched spreading shrub typically grows to a height of 0.6to. A very dense and impenetrable species due to its extremely prickly foliage. The leaves are rigid, NaNsigfig=1NaNsigfig=1 long, prominently grooved and narrow with 5-7 sharply toothed lobes. It blooms from August to October and produces large scented white to cream flowers in clusters in the leaf axils. They may appear in a raceme of up 22 flowers. The smooth to roughish fruit are ovoid 2sigfig=1NaNsigfig=1 long by 1.5sigfig=1NaNsigfig=1 wide with two distinct slightly incurving beaks.[1] [2]
This species was formally described by Robyn Mary Barker in 1990. It is named from the Latin horridus- prickly, referring to the extremely sharp point on the leaf.[1]
Hakea horrida grows from Kondinin south to Lake Grace and east to Esperance in heath and scrubland on sandy-loam with lateritic gravel.[1]
Hakea horrida is classified as "not threatened" by the Western Australian Government.
