Hakea epiglottis is a shrub commonly known as beaked hakea or needlebush hakea [2] and is endemic to Tasmania where populations consist of functional unisexual plants. In a 1989 publication by John Wrigley & Murray Fagg states specimens at Wakehurst Place, an annexe of Kew Gardens London are specimens believed to be 60-70 years old measuring 3 m (9.8 ft) high and wide.

Description

Hakea epiglottis grows to 3 m (10 ft) tall. The inflorescence on male plants have 2-8 flowers whereas female plants 1-3 flowers. The bracts are 3–4 mm (0.3–0.4 cm) long on a stem about 1 mm (0.04 in) long. The flower stems are 3.5–5 mm (0.4–0.5 cm) long with flat white silky hairs extending on to sepals that are 2.5–4 mm (0.1–0.2 in) long and pale yellow inside. The pistil is recurved 5.5–6.5 mm (0.2–0.3 in) long. The style has a small pollen disc which is concave in male flowers but with a conical protuberance in female flowers. Fruit are shaped like the letter 'S' and 1.4–2.6 cm (0.6–1 in) long. Needle-like leaves are 1.5–11 cm (0.6–4 in) long and 1–2 mm (0.04–0.08 in) wide. The young leaves are covered in rust-coloured hairs, which distinguishes this species from the similar Hakea megadenia . Unisexual populations have male plants which do not produce fruit but flowers that produce pollen. Female populations have fruit with no pollen. There are recorded populations of bisexual plants where the fruit occur together with flowers producing pollen. [3] Clusters of white through to bright yellow flowers appear in leaf axils in spring. [4]

Taxonomy and naming

The species was first formally described by Jacques Labillardière in Novae Hollandiae Plantarum Specimen in 1805. [5] The specific epithet (epiglottis) is derived from the Ancient Greek words epi meaning "upon" or "on" [6] :304 and glottis meaning "mouth of the windpipe" perhaps a reference to "a perceived resemblance of the fruit to the upper respiratory system". [4] [6] :538


There are two recognised subspecies:

Distribution and habitat
