Hakea sericea, commonly known as bushy needlewood or silky hakea,[1] 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.

Description

Hakea sericea is a large spreading, bushy shrub and may grow to Шаблон:Convert and does not form a lignotuber. The branchlets are densely covered in grey-whitish short, soft, woolly hairs. The inflorescence appear in umbels of 1–6 flowers in leaf axils, pinkish in bud and maturing to white. The inflorescence rachis is Шаблон:Cvt long and thickly covered in woolly, short, matted white hairs toward the end and rusty coloured at the base. The pedicels are Шаблон:Cvt long, slight to densely covered with long white hairs. The smooth perianth is Шаблон:Cvt long and the pistil Шаблон:Cvt long. The needle-shaped leaves are grooved on the undersurface and up to Шаблон:Convert long and Шаблон:Convert wide and ending in a sharp point Шаблон:Cvt long. The leaves are moderately covered with flattened silky hairs, quickly becoming smooth. The fruit are rough and coarsely wrinkled with a network of veins on the surface, Шаблон:Convert long and Шаблон:Convert wide ending with a short, broad beak to Шаблон:Cvt long.[2][3][4][5]

Taxonomy and naming

Hakea sericea was first formally described by Heinrich Schrader and Johann Christoph Wendland in 1797 and published the description in Sertum Hannoveranum.[6] The genus Hakea is named after Baron von Hake, patron of botany in the 18th century. Sericea meaning silky, referring to the tiny hairs on young growth.[5]

Distribution and habitat

Silky hakea is found from the coast and adjacent ranges of south-eastern Queensland to south-eastern New South Wales. A frost tolerant species, grows in well-drained soil and full sun. A good habitat plant due to its prickly habit and winter flowering. It is also naturalised in Victoria and possibly South Australia.[7]

H. sericea is an invasive weed in some areas outside Australia, specifically in South Africa, New Zealand and Portugal.[8][9]
