Leaves and fruit

Description

Hakea eriantha is a dense non lignotuberous shrub or small tree 1–5 m (3.3–16 ft) tall. Leaves are linear to egg-shaped and 8 to 18.5 cm long and 1 to 30 mm wide. Young leaves are either smooth or with flattened fine hairs, ending with a sharp short point 0.5–1.5 mm (0.020–0.059 in) long. The inflorescence consists of 6-10 cream flowers on a stalk about 2.5–3.5 mm (0.098–0.14 in) long, they appear in the leaf axils. The pedicel is 2.5–6 mm (0.098–0.24 in) long and densely covered with white soft hairs extending onto the lower part of the flower. The white perianth is 3.5–6.5 mm (0.14–0.26 in) long and the style 7–8.5 mm (0.28–0.33 in) long. between August and November. The woody fruit is smooth 1.9–3.2 mm (0.075–0.13 in) long and about 1.2–1.6 mm (0.047–0.063 in) wide with brown blister-like protuberances ending with a short sharp point 3.5–4.5 mm (0.14–0.18 in) long. It is wrinkled and has beak that is about 3 mm long.^{[3][4][5][6][7]}

Taxonomy and naming

Hakea eriantha was first formally described in 1830 by botanist Robert Brown from a specimen collected near the Hastings River by Charles Fraser. The description was published in an addendum to the Supplementum primum Prodromi florae Novae Hollandiae.^[8][9] The specific epithet (eriantha) is derived from the Ancient Greek words erion meaning "wool"^[10]: 864 and anthos meaning "flower"^[10]: 338 referring to the hairy flowers of this hakea.^[5]

Distribution and habitat

Tree hakea occurs in Eucalyptus woodland or forest and the edge of rainforest from Gladstone in Queensland, southward to Gippsland in Victoria.^[4]

Use in horticulture

Hakea eriantha is a fast growing species, suitable for wet cold climates as a screening or hedging plant. A food source for the gang-gang cockatoo (Calocephalon fimbriatum) as they share a similar habitat. Also preferred in some districts by the yellow-tailed black cockatoo (Calyptorhynchus funereus) as a food source.^{[7][11][12][13]}
