Species of legume
Chorizema carinatum is a species of flowering plant in the family Fabaceae and is endemic to the southwest of Western Australia. It is an erect or spreading shrub with sharply-pointed leaves and bright yellow flowers.
Description
Chorizema carinatum is an erect or spreading shrub that typically grows to a height of 10–60 cm (3.9–23.6 in). The leaves are scattered, leathery, oblong or lance-shaped and up to 25 mm (0.98 in) long with a small, rigid, sharply-pointed, down-turned tip on the ends. The flowers are arranged on the ends of branches in racemes 25–50 mm (0.98–1.97 in) long, each flower on a short pedicel. The sepals are 6.0–8.5 mm (0.24–0.33 in) long and silky-hairy, the petals yellow and often barely longer than the sepals. Flowering occurs from October to December.[2][3]
Taxonomy
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.[4][5] In 1992, Joan Taylor and Michael Crisp transferred the species to Chorizema as C. carinatum in Australian Systematic Botany.[6] The specific epithet (carinatum) means "keeled", referring to the leaves.[7]
Distribution and habitat
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.[3]
Conservation status
This pea is listed as "Priority Three" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[3]
