Darwinia divisa Keighery & N.G.Marchant [1]

Darwinia divisa is a species of flowering plant in the myrtle family Myrtaceae and is endemic to a restricted part of the south-west of Western Australia. It is a slender, erect shrub with white flowers and is the only species of its genus with "divided prominent calyx lobes" and a hairy calyx tube. ^[2]

It was first formally described in 2002 by Greg Keighery and Neville Marchant in the Nordic Journal of Botany from specimens collected by Fred Lullfitz near Bendering in 1965. ^[3]

Darwinia divisa is presumed extinct by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, ^{[4] [5]} not having been collected for more than 50 years, despite extensive surveys at the type location and surrounding remnants during 1997-2000. ^[6]
