'''''Chorizema''''', commonly known as '''flame peas''',<ref name="Corrick">{{cite book |last1=Carrick |first1=Margaret G. |last2=Fuhrer |first2=Bruce A. |title=Wildflowers of Southern Western Australia |date=2009 |publisher=Rosenberg Publishing |location=Dural, N.S.W. |isbn=9781877058844 |pages=58–59 |edition=3rd}}</ref> is a genus of flowering plants in the family Fabaceae and is endemic to Australia.
==Description== 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.<ref name="Corrick" /><ref name="RBGS">{{cite web |last1=Wiecek |first1=Barbara |title=Genus ''Chorizema'' |url=https://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&showsyn=&dist=&constat=&lvl=gn&name=Chorizema |publisher=Royal Botanic Garden Sydney |access-date=17 August 2023}}</ref><ref name=FB>{{FloraBase|name=''Chorizema''|id=22422}}</ref>
==Taxonomy== 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''.<ref name="APNI">{{cite web |title=''Chorizema'' |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/474784 |website=Australian Plant Name Index |accessdate=17 August 2023}}</ref><ref name="Labill.">{{cite book |last1=Jacques |first1=Labillardière |title=Relation du Voyage a la Recherche de la Perouse |volume=1 |date=1800 |location=Paris |page=21 |url=https://bibdigital.rjb.csic.es/viewer/13338/?offset=#page=24&viewer=picture&o=bookmark&n=0&q= |access-date=17 August 2023}}</ref> The genus name (''Chorizema'') means "divided thread", Labillardière having noted that the stamens are separate from each other.<ref name="Sharr">{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=69 |edition=3rd}}</ref>
==Distribution== Flame peas are endemic to the south-west of Western Australia, apart from ''C. parviflorum'' that occurs in New South Wales and Queensland.<ref name="Corrick" /><ref name="APNI1">{{cite web |title=''Chorizema parviflorum'' |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/67233 |website=Australian Plant Name Index |accessdate=17 August 2023}}</ref>
==Use in horticulture== 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.<ref>{{cite book|title=RHS A-Z encyclopedia of garden plants|year=2008|publisher=Dorling Kindersley|location=United Kingdom|isbn=978-1405332965|pages=1136}}</ref>
