Bossiaea zarae, commonly known as Princess May winged pea, is a species of flowering plant in the pea family Fabaceae and is endemic to the northern Kimberley region of Western Australia. It is an erect shrub with winged stems, winged cladodes, scale-like leaves and yellow, and reddish-brown flowers.
Bossiaea zarae is an erect shrub that typically grows up to high and wide. The stems are flattened, winged and up to wide, ending in winged cladodes wide. The leaves are reduced to dark brown, narrow egg-shaped scales, long. The flowers are arranged singly or in pairs on pedicels long with overlapping, narrow egg-shaped bracts up to long at the base and narrow egg-shaped bracteoles about long attached to the pedicels. The sepals are long and joined at the base forming a tube, the two upper lobes long and the lower three lobes long. The standard petal is golden yellow with reddish brown marking, a yellow centre and long, the wings uniformly yellow and long, the keel yellowish and long. Flowering has been observed in August and January and the fruit is an oblong pod long.[1]
Bossiaea zarae was first formally described in 2015 by Russell Lindsay Barrett in the journal Nuytsia from specimens collected on Bigge Island in 2008.[2] The specific epithet (zarae) is from "the Arabic and Hebrew name Zara (meaning princess)", referring to the Princess May Ranges where this species was discovered.
Princess May winged pea grows on sandstone ridges and pavements in low shrubland in the Prince Regent National Park and on Bigge Island in the northern Kimberley region of Western Australia.
This bossiaea is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is poorly known and known from only a few locations but is not under imminent threat.[3]
