Description
Daviesia crenulata is a bushy shrub that typically grows to a height of Шаблон:Cvt to Шаблон:Cvt and has hairy, ridged branchlets. Its leaves are reduced to scattered, spreading, broadly egg-shaped phyllodes Шаблон:Cvt long and Шаблон:Cvt wide. The phyllodes have a sharply-pointed tip on the end, a heart-shaped base and wavy edges. The flowers are mostly arranged in groups of two to four in leaf axils on a peduncle Шаблон:Cvt long, each flower on a pedicel Шаблон:Cvt long with oblong bracts about Шаблон:Cvt long at the base. The sepals are Шаблон:Cvt long and joined at the base, the two upper lobes joined for most of their length and the lower three triangular and about Шаблон:Cvt long. The standard is elliptic, yellow-orange with maroon markings, Шаблон:Cvt long and Шаблон:Cvt wide, the wings elliptic, maroon and Шаблон:Cvt long and the keel about Шаблон:Cvt long. Flowering occurs in September and October and the fruit is a flattened, triangular pod Шаблон:Cvt long.[1][2]
