The flowers are arranged singly or in small groups on short side branches ending in a spine, each flower on a dark purplish pedicel Шаблон:Cvt long with several bracts at the base. The sepals are dark red or purplish, joined at the base forming a tube Шаблон:Cvt long, the two upper lobes Шаблон:Cvt long and the lower three lobes Шаблон:Cvt long. The standard petal is orange-yellow with a reddish base and Шаблон:Cvt long, the wings Шаблон:Cvt long and the keel Шаблон:Cvt long.

Taxonomy and naming

Bossiaea atrata was first formally described in 2006 by James Henderson Ross in the journal Muelleria from specimens collected near Manmanning in 1990.[2][3] The specific epithet (atrata) means "clothed in black" referring to the dark pedicels and sepals.[2]

Distribution and habitat

This bossiaea occurs in scattered locations between Manmanning, Lake Grace and Lake King in the Avon Wheatbelt, Coolgardie, Esperance Plains and Mallee biogeographic regions of south-western Western Australia.[1][2]

Conservation status

Bossiaea atrata is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[1] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[4]
