It is a shrub or small tree with rough bark, broad, flat or narrow fleshy leaves and red, orange or yellow flowers.

[3][8] It only grows near Rothsay in the Yalgoo biogeographic region and is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[9] meaning that it is known from only one or a few locations which are potentially at risk.
