Hakea sulcata, commonly known as furrowed hakea, [2] is a flowering plant in the family Proteaceae and is endemic to Western Australia. It is a prickly shrub with grooved, cylindrical leaves, sweetly-scented flowers and relatively small fruit.
Hakea sulcata is a small spreading or upright shrub that grows to a height of 0.4 to 2 metres (1 to 7 ft) and does not form a lignotuber. The branchlets are either thickly or sparsely covered in flattened soft silky hairs at flowering time. The leaves are needle-shaped, thick, pentagonal in cross-section, more or less 2–12.5 cm (0.8–5 in) long and 1–2 mm (0.04–0.08 in) in diameter and grow alternately on the branchlets. The leaves have 6 or 7 shallow longitudinal grooves and end in a sharp point. The leaves occasionally vary in shape, they may be linear, narrowly egg-shaped, flat or concave with prominent veins. The inflorescence consists of 8-14 white, sweetly scented flowers is a single raceme in clusters in the leaf axils or on old wood. The cream-white pedicels are smooth, the perianth cream-white and the pistils 5–9.5 mm (0.20–0.37 in) long. The egg-shaped fruit are the smallest in the genus less than 0.6–0.8 cm (0.2–0.3 in) long and 0.3–0.35 cm (0.12–0.14 in) wide. The surface is generally smooth or slightly warty becoming rough with age and end in a point. [2] [3] [4]
Hakea sulcata was first formally described 1810 by Robert Brown and the description was published in Transactions of the Linnean Society . [5] [6] Named from the Latin sulcatus - grooved, referring to the leaf structure. [2]
Furrowed hakea is endemic to an area in the South West, Great Southern and the Goldfields-Esperance regions of Western Australia from Gingin in the north to Albany in the south, Augusta in the west and Esperance in the east. It grows in sandy or clay soils over or around areas of laterite. [4]
Hakea sulcata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [4]
Hakea trifurcata, commonly known as two-leaf, two-leaved hakea, or kerosene bush, is a shrub, endemic to the south-west of Western Australia. The species has two leaf forms, needle-like or oblong egg-shaped. Unlike most hakea species the fruit remain green at maturity and resemble the broader leaf form. The mimicry creates a camouflage, reducing predation of the seed by granivores in particular cockatoos.
