Daviesia decurrens
Daviesia decurrens, commonly known as prickly bitter-pea, is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is spreading, erect, or low-lying shrub with scattered, sharply-pointed, narrow triangular phyllodes, and yellowish pink and velvety red flowers. Description
Daviesia decurrens is a spreading, erect or low-lying, glabrous shrub that typically grows to  high and  wide. Its leaves are reduced to scattered, sharply-pointed, triangular to tapering, decurrent phyllodes  long and  wide at the base. The flowers are arranged in groups of three to seven in leaf axils on a peduncle  long, the rachis up to , each flower on a pedicel  long with bracts about  long. The sepals are  long and joined at the base, the two upper lobes minute and the lower three  long. The standard petal is elliptic or egg-shaped,  long,  wide and yellowish pink with a velverty red base. The wings are  long and red, and the keel is  long and red. Flowering mainly occurs from May to August and the fruit is an inflated, broadly triangular pod  long. Taxonomy and naming
Daviesia decurrens was first formally described in 1844 by Carl Meissner in Lehmann's Plantae Preissianae. The specific epithet (decurrens) means "decurrent". In 2017, Michael Crisp and Gregory T. Chandler described two subspecies in Phytotaxa, and the names are accepted by the Australian Plant Census:
 Daviesia decurrens Meisn. subsp. decurrens has strongly decurrent phyllodes up to  long and up to  wide;
 Daviesia decurrens subsp. hamata Crisp & G.Chandler has scarcely decurrent, cylindrical phyllodes up to  long and  wide. Distribution and habitat
Prickly bitter-pea grows is found from near Dongara to Busselton and eastwards to near Albany. Subspecies decurrens mostly grows in eucalypt woodland and forest, sometimes in swampland. Subspecies hamata grows in heathland and occurs further inland than subsp. decurrens, from Marchagee to Brookton and inland to near Coolgardie. Conservation status
Both subspecies of Daviesia decurrens are classified as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions. References
