Daviesia crenulata is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a bushy shrub with broadly egg-shaped phyllodes with a sharply-pointed end and wavy edges, and uniformly yellow-orange and maroon flowers.
Daviesia crenulata is a bushy shrub that typically grows to a height of to and has hairy, ridged branchlets. Its leaves are reduced to scattered, spreading, broadly egg-shaped phyllodes long and wide. The phyllodes have a sharply-pointed tip on the end, a heart-shaped base and wavy edges. The flowers are mostly arranged in groups of two to four in leaf axils on a peduncle long, each flower on a pedicel long with oblong bracts about long at the base. The sepals are long and joined at the base, the two upper lobes joined for most of their length and the lower three triangular and about long. The standard is elliptic, yellow-orange with maroon markings, long and wide, the wings elliptic, maroon and long and the keel about long. Flowering occurs in September and October and the fruit is a flattened, triangular pod long.[1]
Daviesia crenulata was first formally described in 1853 by Nikolai Turczaninow in the Bulletin de la Société Impériale des Naturalistes de Moscou.[2] [3] The specific epithet (crenulata) means "crenulate", referring to the edge of the phyllodes.[4]
This species of pea grows in heath, mallee-heath and forest and mainly occurs in the Stirling Range in the Avon Wheatbelt, Esperance Plains and Mallee biogeographic regions of south-western Western Australia.
Daviesia crenulata is classified as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
