Daviesia preissii
Daviesia preissii is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a glabrous shrub with scattered, vertically flattened, tapering, narrowly egg-shaped to elliptic, sharply-pointed phyllodes and yellow and red flowers. Description
Daviesia preissii is a glabrous shrub, often low and spreading, typically  high and  wide. It has dull green, vertically flattened, tapering, narrowly egg-shaped or elliptic phyllodes  long and  wide that diverge from the branchlets at angles of 60–90°. The flowers are usually arranged singly or in pairs in leaf axils on a peduncle  long, each flower on a pedicel  long. The sepals are  long with narrowly triangular lobes about  long. The standard petal is broadly elliptic,  long,  wide, and yellow with a red tinge near the base. The wings are  long and red, the keel  long and red. Flowering mainly occurs from December to February and the fruit is a partly flattened, triangular pod  long with the remains of the style attached. Taxonomy and naming
Daviesia preissii was first formally described in 1844 by Carl Meissner in Lehmann's Plantae Preissianae from specimens collected in 1841. The specific epithet (preissii) honours Ludwig Preiss, who collected the type specimens. Distribution and habitat
This daviesia grows in open forest or in kwongan heath on the Darling Range and in the far south-west of Western Australia as far east as Albany and the Stirling Range. Conservation status
Daviesia preissii is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions. References
