Шаблон:Short description Шаблон:Speciesbox

Daviesia pachyloma is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is an erect, bushy or spreading shrub with zigzagging branches, sharply-pointed, narrowly elliptic to linear phyllodes, and yellow and red flowers.

Description

Daviesia pachyloma is an erect, bushy or spreading shrub that typically grows to a height of up to about Шаблон:Cvt and has more or less glabrous, zigzagging branches. Its phyllodes are scattered, erect and narrowly elliptic to linear, Шаблон:Cvt long and Шаблон:Cvt wide with a sharply pointed tip and thickened edges. The flowers are arranged singly in leaf axils on a peduncle up to Шаблон:Cvt long, with up to five leaf-like bracts at the base, the rachis up to Шаблон:Cvt long. Each flower is on a pedicel Шаблон:Cvt long, the sepals Шаблон:Cvt long and joined at the base with triangular lobes Шаблон:Cvt long. The standard petal is egg-shaped with a notched centre, Шаблон:Cvt long and Шаблон:Cvt wide, and yellow with a red border and fine red veins, the wings about Шаблон:Cvt long and yellow, the keel Шаблон:Cvt long and pale creamy yellow. Flowering occurs from March to January and the fruit is a flattened, triangular pod about Шаблон:Cvt long.[1][2]

Taxonomy and naming

Daviesia pachyloma was first formally described in 1853 by Nikolai Turczaninow in the Bulletin de la Société Impériale des Naturalistes de Moscou.[3][4] The specific epithet (pachyloma) means "thick hem", referring to the edge of the phyllodes.[5]

The original publication gave the name Daviesia pachylima, a transcription error from Turczaninow's handwriting. The epithet pachylina has no etymological meaning, and may explain why George Bentham changed the spelling to pachylina ("thick thread")[5] in Flora Australiensis.[1][6]

Distribution and habitat

This daviesia grows in scattered populations in woodland between Manmanning, Zanthus, Kulin and Holt Rock in the Avon Wheatbelt, Coolgardie, Great Victoria Desert and Mallee biogeographic regions of south-western Western Australia.[1][2]

Conservation status

Daviesia pachyloma is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[2]
