Daviesia tortuosa is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a spreading, glabrous shrub with tangled, zigzagging branchlets, sharply-pointed, narrowly elliptic phyllodes, and yellow flowers with faint orange markings.

Description

Daviesia tortuosa is a spreading, glabrous and glaucous shrub that typically grows up to Шаблон:Cvt high, Шаблон:Cvt wide and has many tangled, wiry, zigzagging branchlets. Its phyllodes are scattered, narrowly elliptic to narrowly egg-shaped with the narrower end towards the base, Шаблон:Cvt long, about Шаблон:Cvt wide and sharply pointed. The flowers are usually arranged in clusters of two to five in leaf axils on a peduncle Шаблон:Cvt long, the rachis Шаблон:Cvt long, each flower on a pedicel Шаблон:Cvt long. The sepals are Шаблон:Cvt long and joined at the base, the upper two lobes joined for most of their length and the lower three triangular and about Шаблон:Cvt long. The standard petal is broadly elliptic, Шаблон:Cvt long and wide, and yellow with orange markings. The wings are Шаблон:Cvt long and rich yellow, the keel about Шаблон:Cvt long and rich yellow. Flowering occurs from January to April and the fruit is a triangular pod Шаблон:Cvt long.[1][2]

Taxonomy

Daviesia tortuosa was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens he collected near Lake Grace in 1978.[1][3] The specific epithet (tortuosa) means "zig-zag", referring to the branching of this species.[4]

Distribution and habitat

This daviesia grows in kwongan heath roughly between Kulin, Dumbleyung and Lake Grace in the Avon Wheatbelt and Mallee biogeographic regions of south-western Western Australia.[1][2]

Conservation status

Daviesia speciosa is classified as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[5]
