Hakea trineura is a species of flowering plant in the family Proteaceae. It is endemic to Queensland, Australia. The branches and leaves are covered with rusty hairs and the pendulous flowers are greenish-yellow.
Hakea trineura is a multi-stemmed shrub growing to 1–3 m (3–10 ft) high and forms a lignotuber. The branchlets and new leaf growth have flattened, brown, short soft silky hairs, or are smooth. The leaves grow on a petiole about 1–2.5 cm (0.39–0.98 in) long. They are narrowly elliptic to egg-shaped 7–20 cm (3–8 in) long by 1.3–7 cm (0.5–3 in) wide with three distinct longitudinal veins. The leaves narrow gradually to the apex ending either with a sharp point or rounded. The inflorescence consists of 60–80 greenish-yellow flowers on a smooth or with sparsely flattened soft hairs on a rachis up to 40–70 mm (2–3 in) long. The mid-green pedicel 2.3–3 mm (0.09–0.1 in) long and smooth. The deep yellow perianths are 7–8.5 mm (0.3–0.3 in) long and are smooth or with a few hairs when in bud. The styles are mid-green and the pistil 18–26 mm (0.71–1.02 in) long. Flowering occurs from May to September and the fruit are smooth, obliquely egg-shaped 2–4 cm (0.8–2 in) long by 1.5–2 cm (0.6–0.8 in) wide and slightly curved.[3][4][5]
Taxonomy and naming
Hakea trineura was first formally described in 1868 by Ferdinand von Mueller who gave it the name Grevillea trineura and published the description in Fragmenta Phytographiae Australiae.[6][7] In 1868, Mueller changed the name to Hakea trineura.[8] It is said to be named from the Greek trineura, referring to the three-veined leaves.[3] Trineura is however not attested in ancient Greek.[9]
