Description

Daviesia dielsii is an intricately-branched shrub that typically grows to about Шаблон:Cvt high and Шаблон:Cvt wide. Its leaves are reduced to moderately crowded, sharply-pointed, vertically compressed, egg-shaped phyllodes with the narrower end towards the base, Шаблон:Cvt long, Шаблон:Cvt wide and thick. The flowers are arranged singly in leaf axils on a pedicel Шаблон:Cvt long with bracts Шаблон:Cvt long in clusters at the base. The sepals are Шаблон:Cvt long and joined at the base with lobes about Шаблон:Cvt long, the two upper lobes are joined and the lower three triangular. The standard petal is elliptic, Шаблон:Cvt long and wide, and yellow with a red centre. The wings are Шаблон:Cvt long and maroon, and the keel is Шаблон:Cvt long and red. Flowering mainly occurs from March to August and the fruit is an inflated, triangular pod Шаблон:Cvt long.[2][3]

Daviesia dielsii was first formally described in 1904 by Ernst Georg Pritzel in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie.[4][5] The specific epithet (dielsii) honours Ludwig Diels.[6]

Distribution and habitat

Diels' daviesia grows in kwongan heath and on disturbed roadsides in the Dalwallinu-Moora-Three Springs area where it is known from fifteen populations.[1][2][3]
