## Description

*Hakea constablei* is a compact rounded shrub to small tree growing to 1.8 to 6 metres (5.9 to 19.7 ft) high. The needle-shaped bright green pointed leaves are 3 to 11 centimetres (1 to 4 in) long and 1 to 1.6 millimetres (0.0 to 0.1 in) wide. New growth is hairy, branches are arching hanging loosely and despite the pointed leaves not particularly prickly. The bright green leaves are needle-shaped and about 10 cm (3.9 in) long. It produces cream-white flowers from September to November on the previous seasons stems. Each [inflorescence](/source/Inflorescence) is composed of 6 to 12 flowers with a cream white [perianth](/source/Perianth) that is 3-4.2 mm in long. The [style](/source/Style_(botany)) about 10 mm (0.39 in) long with a cone shaped [stigma](/source/Stigma_(botany)). The large rounded fruit are 4.3 to 5.5 centimetres (1.69 to 2.17 in) long and 3 to 3.5 cm (1.18 to 1.38 in) wide. The dark grey surface is covered with warty protuberances, ending with horns 0.5 to 1.8 mm (0.020 to 0.071 in) long. The dark brown seed are 2.7 to 3.7 cm (1.06 to 1.46 in) long with a wing down one side.[2][3][4][5]

## Taxonomy and naming

*Hakea constablei* was initially found in 1899 but the specimen was inadvertently stored with another Hakea. It was overlooked until 1950 when E.F. Constable collected the species near the [Blue Mountains](/source/Blue_Mountains,_New_South_Wales) and brought it to the attention of botanists at the [Sydney Herbarium](/source/National_Herbarium_of_New_South_Wales). The species was first formally described by the botanist [Lawrence Alexander Sidney Johnson](/source/Lawrence_Alexander_Sidney_Johnson) in 1962 and published in *Contributions from the New South Wales National Herbarium*.[3][6] The [specific epithet](/source/Botanical_name) honours Ernie Constable a former seed and plant collector for the Royal Botanic Gardens in Sydney. He collected mostly in New South Wales, including the type specimen for the species.[2][7]

## Distribution and habitat

*Hakea constablei* is [endemic](/source/Endemism) to an area in the [Blue Mountains](/source/Blue_Mountains_(New_South_Wales)) and [Wollondilly](/source/Wollondilly) catchment in [New South Wales](/source/New_South_Wales) where it is found among elevated [sandstone](/source/Sandstone) outcrops as part of sclerophyll forest communities.[2]

## Conservation status

*Hakea constablei* is considered rare, ROTAP conservation code 2RCa, Briggs, Leigh and Hartley 1996.[2]
