Petrophile
''Petrophile'' is a genus of evergreen shrubs, in the family Proteaceae. The genus is endemic to Australia. Commonly known as conebushes, they typically have prickly, divided foliage and produce prominently-displayed pink, yellow or cream flowers followed by grey, conical fruits. Taxonomy The genus ''Petrophile'' was first formally described in 1809 by Joseph Knight in ''On the cultivation of the plants belonging to the natural order of Proteeae'', preempting publication of the same name by Robert Brown in his book '' On the natural order of plants called Proteaceae''. The name ''Petrophile'' is derived from the Greek words ''petra'' = rock and ''philos'' = seeking or preferring, referring to the rocky habitat in which some species grow.
