Hakea decurrens, commonly known as bushy needlewood, [2] is a species of shrub or small tree in the family Proteaceae.
Hakea decurrens is a semi-prostrate to erect scrambling bush or small tree 0.4–5 m (1–20 ft) tall. Smaller branches have short densely matted silky hairs, occasionally some quickly becoming smooth. Leaves are needle-shaped, widely spreading horizontally are 1.5–8 cm (0.6–3 in) long and 0.7–1.6 mm (0.03–0.06 in) wide. The smooth leaves are grooved on the underside ending with a sharp point 1–3.5 mm (0.04–0.1 in) long. The inflorescence consists 1-6 white or pink flowers on a short white or rusty slightly hairy or densely matted hairy short stalk. The hairs extending onto a 1.2–4.8 mm (0.047–0.19 in) long pedicel. The smooth perianth is 4.2–7.2 mm (0.17–0.28 in) long. The style is 8.5–12.2 mm (0.33–0.48 in) long. A profusion of flowers appear in leaf axils from May to September. The grey woody fruit are broadly egg-shaped 1.8–3.5 cm (0.7–1 in) long and 1–3 cm (0.39–1.2 in) wide covered in distinct warts ending in a prominent beak with two small horns. [2] [3] [4] [5] [6]
Hakea decurrens was first formally described in 1830 by Robert Brown in Supplementum primum prodromi florae Novae Hollandiae . [7] The specific epithet (decurrens) is a Latin word, meaning "decurrent" or "prolonged below the point of insertion", referring to the insertion of the leaf on the stem. [5]
In 1996 William Robert Barker described three subspecies of Hakea decurrens in the Journal of the Adelaide Botanic Gardens and the names are accepted by the Australian Plant Census [8]
The main differences are their fruit and hair characteristics on smaller branches.
The species is native and widespread in New South Wales, Victoria and Tasmania in Australia. Additionally it is naturalised in South Australia and Portugal.
Three subspecies are currently recognised:
Hakea is a genus of about 150 species of plants in the Family Proteaceae, endemic to Australia. They are shrubs or small trees with leaves that are sometimes flat, otherwise circular in cross section in which case they are sometimes divided. The flowers are usually arranged in groups in leaf axils and resemble those of other genera, especially Grevillea. Hakeas have woody fruit which distinguishes them from grevilleas which have non-woody fruit which release the seeds as they mature. Hakeas are found in every state of Australia with the highest species diversity being found in the south west of Western Australia.
Hakea salicifolia commonly known as the willow-leaved hakea, is species of flowering plant that is endemic to eastern Australia. It is an adaptable, fast growing small tree or shrub with attractive foliage and cream white flowers.
Hakea bakeriana is a shrub in the family Proteaceae and is endemic to the Central Coast of New South Wales. It is a dense shrub with sharply pointed, cylinder-shaped leaves and pink to crimson flowers in groups of between four and twelve. The fruit is a rough, wrinkled follicle which terminates in a short beak.
Hakea pachyphylla is a flowering plant in the family Proteaceae and is endemic to the upper Blue Mountains in New South Wales. It is a small shrub with stiff, needle-shaped leaves and clusters of yellow flowers. Formerly thought to be a Blue Mountains form of Hakea propinqua.
Hakea drupacea, commonly known as sweet-scented hakea, is a tree or shrub which is native to south west Western Australia.
Hakea teretifolia, commonly known as the dagger hakea, is a species of woody shrub of the family Proteaceae and is common on heathlands in coastal eastern Australia from northern New South Wales through to Victoria and Tasmania. A very prickly shrub, it is rarely cultivated but easy to grow.
Hakea sericea, commonly known as bushy needlewood or silky hakea, is a large shrub with a profusion of mainly white flowers from July for several months. It is endemic to eastern Australia. It has become an environmental weed in some countries.
Hakea gibbosa, commonly known as hairy hakea or needlebush hakea, is a shrub of the family Proteaceae, and is endemic to south eastern Australia. It has very prickly foliage, cream-yellowish flowers from April to July, and provides shelter for small birds. It has become an environmental weed in South Africa and New Zealand, where it had been introduced for use as a hedge plant.
Hakea rugosa, commonly known as wrinkled hakea or dwarf hakea, is a shrub of the family Proteaceae native to Australia. It has sharp needle-shaped leaves and white or cream fragrant flowers in profusion from August to October.
Hakea chordophylla, commonly known as bootlace oak, bootlace tree, corkwood, or bull oak, is a species of shrub or small tree in the family Proteaceae found in central and northern Australia. Bears very showy golden yellow, pale green or cream nectar rich flowers in winter.
Hakea ochroptera is a species of flowering plant in the family Proteaceae and is endemic to a restricted area of New South Wales. It is a shrub with long, needle-shaped leaves and an abundance of cream-white flowers in spring.
Hakea tephrosperma commonly known as hooked needlewood, is a shrub or small tree species in the family Proteaceae. It has cream flowers, needle-shaped leaves and is one of the taller species adaptable for dry to temperate locations.
Hakea laevipes is a shrub in the family Proteaceae. A widespread species found growing on coastal and tableland locations mainly in eastern New South Wales, with scattered populations in south-eastern Queensland.
Hakea pandanicarpa is a shrub species in the family Proteaceae. It is endemic to south-west Western Australia.
Olearia asterotricha, commonly known as rough daisy-bush, is a species of flowering plant in the family Asteraceae. A tall shrub with white, mauve or blue daisy like flowers growing from the Blue Mountains in New South Wales to western Victoria, Australia.
Hakea pendens is a flowering plant in the family Proteaceae and endemic to a small area in the Goldfields-Esperance regions of Western Australia. It is a small shrub with needle-like leaves and pendulous pink flowers.
Hakea stenophylla is a shrub or tree in the family Proteacea, with sweetly scented creamy-white flowers. It is endemic to Western Australia.
Hakea vittata, commonly known as the striped hakea, hooked needlewood, is a shrub of the family Proteaceae. Restricted to an area on the Eyre Peninsula and the Gawler Range in South Australia and small areas in eastern Victoria.
Hakea fraseri, is a species of shrub or small tree commonly known as the corkwood oak, is a shrub in the family Proteaceae and is endemic to northern New South Wales. It has furrowed bark, pendulous foliage and creamy-white flowers in spring.
Hakea leucoptera subsp. sericipes is a small tree with cylinder-shaped leaves and clusters of up to forty-five white fragrant flowers. It is found in northwestern New South Wales, Queensland and Western Australia.
