Hakea falcata, commonly known as sickle hakea,[2] is a shrub in the family Proteacea and is endemic to southern Western Australia. It has narrow egg-shaped leaves, cream flowers and blooms in spring.

Description

The erect loose non-lignotuberous shrub typically grows to a height of 2 to 4 metres (6.6 to 13.1 ft).[3] The branchlets have a patchy covering of pale rusty-brown coloured hairs. The flat curved evergreen leaves have a linear to narrowly obovate shape with a length of 5 to 14 centimetres (2.0 to 5.5 in) and a width of 3 to 14 millimetres (0.118 to 0.551 in) and have three or rarely four longitudinal veins.[4] It blooms from September to November and produces white-yellow or white-pink flowers.[3] Each solitary inflorescence contains 25 to 40 flowers with a creamy coloured perianth and a cream pistil with a length of 4.5 to 6.5 mm (0.177 to 0.256 in). After flowering an obliquely narrowly ovate, curved and prominently beaked fruit is produced which is 2 to 2.5 cm (0.8 to 1.0 in) in length and 7 to 10 mm (0.276 to 0.394 in) wide. The fruit contain narrowly ovate shaped blackish brown seeds with a wing down one side.[4]

Taxonomy and naming

The species was first formally described by the botanist Robert Brown in 1830 as part of the work Supplementum primum prodromi florae Novae Hollandiae.[5][6] The only synonym is Hakea falcata var. falcata as described by Carl Meissner.[7] The specific epithet is taken from the Latin word falcatus meaning curved like a sickle, referring to the shape of the leaves.[4]

Distribution

It is endemic to an area along the coast in the South West and Great Southern regions of Western Australia between around Busselton and Albany and with a small population isolated in the Stirling Range around Cranbrook. It is found in winter wet depressions and other damp areas growing in peaty-sandy or sandy-clay soils.[3] The shrub is often part of the understorey in jarrah forest or open Eucalypt woodland communities.[4]
