Grevillea hystrix (Proteaceae), a poorly known species from sandplain country in Western Australia’s Coolgardie bioregion

The new species of Grevillea Knight (Proteaceae) described below was first collected from an area of sandplain near Koolyanobbing by William Muir in 2013 as part of industry-funded survey work. It was recognised as an undescribed species the following year upon examination of material donated to the Western Australian Herbarium, and subsequently was targeted by Herbarium staff for further collections and observations. Despite extensive areas of sandplain habitat in the region, it remains known from only a single population.
