Subspecies xiphophylla

Daviesia intricata 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 densely tangled branches, sharply-pointed, needle-shaped or flattened phyllodes and apricot-yellow and dark red flowers.

Description

Daviesia intricata is a glabrous shrub that typically grows to a height of up to Шаблон:Cvt, and has densely tangled branches. Its phyllodes are mainly confined to near the ends of branchlets, sharply-pointed, needle-shaped, mostly Шаблон:Cvt long, Шаблон:Cvt wide and needle-shaped or flattened, depending on subspecies. The flowers are arranged in clusters of three to seven 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 lower three lobes longer than the upper two. The standard petal is elliptic with a notched tip, Шаблон:Cvt long and apricot yellow with a reddish-black centre, the wings Шаблон:Cvt long and dark red, and the keel Шаблон:Cvt long and dark red. Flowering occurs from May to August and the fruit is broadly triangular, slightly inflated pod Шаблон:Cvt long.[1][2]

Taxonomy and naming

Daviesia intricata was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens he collected in Tutanning Reserve near Pingelly in 1980.[3] The specific epithet (intricata) means "entangled", referring to the habit of this species.[4]

In the same journal article, Crisp described two subspecies, and the names are accepted by the Australian Plant Census:

  • Daviesia intricata Crisp subsp. intricata;[5][6]
  • Daviesia intricata subsp. xiphophylla Crisp[7] is a smaller (up to Шаблон:Cvt tall) plant than the autonym and has phyllodes that are vertically flattened, rather than needle-shaped.[1][8]

Distribution and habitat

Subspecies intricata grows in woodland, mallee, heathland and shrubland between the Charles Gardner Reserve near Tammin, Dumbleyung and Ravensthorpe and subsp. xiphophylla is found in heathland and mallee scrub from near Southern Cross to Marble Rocks east of Hyden.[1][6][8]

Conservation status

Both subspecies of D. intricata are listed as "not threatened" by the Department of Biodiversity, Conservation and Attractions.[6][8]
