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 pachyphylla is a non lignotuberous compact to spreading single stemmed shrub growing to 0.3–2 m (1–7 ft) high. The inflorescence consists of 1-7 yellow flowers that appear in axillary clusters in spring. The white main stalk is 0.5–1.2 mm (0.02–0.05 in) long covered with densely covered with short matted hairs. [2] The small branches are ribbed and densely covered with soft mid-red matted hairs quickly becoming smooth or on occasion remain until flowering. The stiff needle-like leaves vary in length between 1–5.5 cm (0.4–2 in) long and 1.1–1.8 mm (0.04–0.07 in) wide with sparse flat hairs but quickly becoming smooth ending with a small point. Flowers from August to October followed by oval shaped fruit with small blunt wart-like protuberances 2.9–3.5 cm (1–1 in) long and 2.3–2.6 cm (0.9–1 in) wide with a short broad beak with obscure or no horns.

Hakea pachyphylla was first formally described in 1827 by Curt Sprengel from an unpublished description by Franz Sieber in Systema Vegetabilium. [4] [5] The specific epithet (pachyphylla) is derived from the Ancient Greek words pachys (παχύς) meaning "thick" and phyllon (φύλλον) meaning "leaf" [6] referring to the thickness of the leaves. [7]
Hakea pachyphylla has a restricted distribution occurring only in the Mount Victoria, Leura, Newnes area in swamp or heath or mallee-heath, occasionally on sandstone. [8]
