Description

Brachyloma delbi is an erect, open shrub that usually grows to a height of 1.0–1.5 m (3 ft 3 in – 4 ft 11 in) and has sparsely hairy branchlets. The leaves are linear, 4.0–8.0 mm (0.16–0.31 in) long, and 0.75–1.0 mm (0.030–0.039 in) wide on a petiole 0.5–1 mm (0.020–0.039 in) long, with the edges rolled under and a small hard point on the tip. The flowers are arranged singly in leaf axils on a peduncle 0.75–1.0 mm (0.030–0.039 in) long with 2 sessile bracts 0.9–1.0 mm (0.035–0.039 in) long at the base. The sepals are egg-shaped, 1.5–2.0 mm (0.059–0.079 in) long and 1.0–1.5 mm (0.039–0.059 in) wide. The petals are joined to form an urn-shaped tube 3.0–4.5 mm (0.12–0.18 in) long with broadly triangular lobes about 1 mm (0.039 in) long. Flowering occurs from April to May and the fruit is a spherical drupe 3–4 mm (0.12–0.16 in) in diameter. [2] [3]

Taxonomy and naming

Brachyloma delbi was first formally described in 2005 by Raymond Cranfield in the journal Nuytsia from specimens collected near Kulin in 1995. [2] [4] The specific epithet (delbi) is a Noongar word meaning "leaf", referring to the characteristic leaves of this species. [2]

Distribution

This species of shrub grows in open woodland and is only known from the type location in the Mallee bioregion of south-western Western Australia. [3]

Conservation status

Brachyloma delbi is listed as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, [3] meaning that it is in danger of extinction. [5]
