Chorizema carinatum is an erect or spreading shrub that typically grows to a height of . The leaves are scattered, leathery, oblong or lance-shaped and up to long with a small, rigid, sharply-pointed, down-turned tip on the ends. The flowers are arranged on the ends of branches in racemes long, each flower on a short pedicel. The sepals are long and silky-hairy, the petals yellow and often barely longer than the sepals. Flowering occurs from October to December.[1]
This species was first formally described in 1844 by Carl Meissner who gave it the name Callistachys carinata in Lehmann's Plantae Preissianae from specimens collected in Kent in 1840.[2] [3] In 1992, Joan Taylor and Michael Crisp transferred the species to Chorizema as C. carinatum in Australian Systematic Botany.[4] The specific epithet (carinatum) means "keeled", referring to the leaves.[5]
Chorizema carinatum grows in sand and sandy clay in the Avon Wheatbelt, Esperance Plains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.
This pea is listed as "Priority Three" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
