The Lesueur Hakea is a many-stemmed shrub growing to 1.2 m tall and 2 m diameter, with white or pink flowers, becoming deep red with age (Barker et al. 1999).

This species occurs WA in the Gairdner Range/Mt Lesueur area and eastwards for approx. 35 km, and in two disjunct locations, one near Eneabba to the N, and the other near Dandaragan to the S (Patrick & Brown 2001; Brown et al. 1998; Hopper et al. 1990)

Five populations are known. Three, including the two largest, contain a total of about 200 plants and occur in an area proposed as a Nature Reserve, but which is also subject to a mining claim. The fourth population consists of a single plant occuring in a C class Nature Reserve. The fifth population consists of around 20-30 plants and is on uncleared farming land (Rye 1982b).

Specimens have been cited from: Mt. Lesueur; 110 km N of Regans Ford; 14 km W of Brand Hwy, Gairdner River; 15 km SE of Eneabba (Barker et al. 1999).

This Hakea grows in low heath in grey sand and lateritic gravel or laterite boulders on hilltops and ridges, or occasionally with emergent Eucalyptus todtiana in white or yellow grey sand. Associated species include Banksia candolleana, B. micrantha, Lambertia multiflora, Hakea obliqua, Adenanthos cygnorum, Allocasuarina humilis, Stirlingia sp. and Dryandra species (Hopper et al. 1990; Patrick & Brown 2001; Brown et al. 1998; Barker et al. 1999).

The plants are lignotuberous. Flowering occurs from May to June (Rye & Hopper 1981; Rye 1982b; Barker et al. 1999).

The flowers produce a strong perfume and presumably are pollinated by insects. Fruit set is variable, and the plants may require cross pollination. Fruits retain their seed for a long time. The plants are probably long-lived (Rye 1982b; Hopper et al. 1990).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
