Chorizema, commonly known as flame peas,[3] is a genus of flowering plants in the family Fabaceae and is endemic to Australia.
Description
[edit]Plants in the genus Chorizema are mostly shrubs or subshrubs, sometimes climbers, usually with simple leaves arranged in opposite pairs, the flowers usually arranged in racemes, each flower on a short pedicel. The sepal lobes are more or less equal, the upper pair broader and partly joined, the standard petal more or less round or kidney-shaped, the wings oblong and much longer than the keel. The fruit is an oval pod containing 4 to 32 seeds.[3][4][5]
Taxonomy
[edit]The genus Chorizema was first formally described in 1800 by Jacques Labillardière in his Relation du Voyage à la Recherche de la Pérouse, and the first species he described (the type species) was Chorizema ilicifolium.[6][7] The genus name (Chorizema) means "divided thread", Labillardière having noted that the stamens are separate from each other.[8]
Distribution
[edit]Flame peas are endemic to the south-west of Western Australia, apart from C. parviflorum that occurs in New South Wales and Queensland.[3][9]
Use in horticulture
[edit]This genus of peas is valued in cultivation for their colourful flowers. Most species do not tolerate frost, and in temperate regions require the protection of glass.[10]
