Jacksonia forrestii, commonly known as broom bush,[1] is a species of flowering plant in the family Fabaceae and is endemic to the north-west of Australia. It is an erect, slender, weeping shrub or tree with sharply pointed phylloclades, yellow to yellow-orange flowers without markings, and woody, hairy pods.
Jacksonia forrestii is an erect, slender, weeping shrub or tree that typically grows up to high and wide, its branches greyish green and ribbed. Its end branches are sharply-pointed phylloclades, its leaves reduced to narrowly egg-shaped to egg-shaped, reddish brown scales, long and wide. The flowers are densely arranged near the ends of branches on a straight pedicel long. There are egg-shaped bracteoles long and wide on the pedicels. The floral tube is long and the sepals are membranous, the upper lobes long and wide, the lower lobes longer but narrower. The flowers are yellow to yellow-orange without markings, the standard petal long and wide, the wings long, and the keel is long. The filaments of the stamens are green, long. Flowering occurs from March to November, and the fruit is a woody, hairy, elliptic pod, long and wide.[2]
Jacksonia forrestii was first formally described in 1887 by Ferdinand von Mueller in the Proceedings of the Linnean Society of New South Wales from specimens collected by Alexander Forrest.[3] The specific epithet (forrestii) honours the collector of the type specimens.[4]
This species of Jacksonia grows in woodland with a grassy understorey and is widespread in the eastern Kimberley of Western Australia and low-lying areas in the western Northern Territory.
Jacksonia forrestii is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions and of "least concern" under the Northern Territory Territory Parks and Wildlife Conservation Act.
