Chorizema ulotropis

Chorizema ulotropis is a species of flowering plant in the family Fabaceae and is endemic to the southwest of Western Australia. It is a sprawling, open, more or less prostrate shrub that typically grows to a height of 45 cm (18 in) high. It has orange-yellow flowers from July to September.[2]

It was first formally described in 1992 by Joan Taylor and Michael Crisp in the journal Australian Systematic Botany, from specimens collected near Jerramungup.[3]

Chorizema ulotropis grows in sand with gravel or laterite on granite outcrops and flats in the Esperance Plains, Jarrah Forest and Mallee bioregions of south-western Western Australia.[2] The specific epithet (ulotropis) means "a curled keel", referring to the woolly tips on the keeled petals.[4]
