Description

Daviesia megacalyx is an erect, glabrous shrub that typically grows to a height of Шаблон:Cvt. Its phyllodes are scattered, elliptic to narrowly egg-shaped with the narrower end towards the base, Шаблон:Cvt long, Шаблон:Cvt wide and leathery. The flowers are arranged in groups of one or two in leaf axils on a peduncle Шаблон:Cvt long, the rachis up to Шаблон:Cvt long, each flower on a pedicel Шаблон:Cvt long. The sepals are Шаблон:Cvt long and joined at the base, the lobes more or less similar, triangular and about Шаблон:Cvt long. The standard petal is broadly egg-shaped, about Шаблон:Cvt long and apricot with a maroon base and intensely yellow centre. The wings are about Шаблон:Cvt long and deep pink, and the keel about Шаблон:Cvt long and deep pink. Flowering occurs in August and September and the fruit is a flattened, leathery triangular pod Шаблон:Cvt long.[1][2]

Taxonomy and naming

Daviesia megacalyx was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens collected near Ravensthorpe in 1979.[3] The specific epithet (megacalyx) means "large calyx", referring to the sepals.[4]

Distribution and habitat

This daviesia grows in mallee-heath and dense shrubland near Ravensthorpe in the Esperance Plains biogeographic region of south-western Western Australia.[1][2]

Conservation status

Daviesia megacalyx is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Biodiversity, Conservation and Attractions. The main threats to the species include inappropriate fire regimes, habitat loss and degradation by mining activities and dieback caused by Phytophthora.[2][5]
