Description

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] Small branches are ribbed and densely covered with soft mid-red matted hairs quickly becoming smooth or on occasion remain until flowering. 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.[2][3]

Taxonomy and naming

Hakea pachyphylla was first formally described in 1827 by Curt Sprengel from an unpublished description by Franz Sieber in Systema Vegetabilium.[1] The specific epithet (pachyphylla) is derived from the Ancient Greek words pachys (παχύς) meaning "thick" and phyllon (φύλλον) meaning "leaf"[4] referring to the thickness of the leaves.[5]

Distribution and habitat

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.[6]

gollark: Well, if you don't have ender modems, you need some sort of central HTTP-based relay.
gollark: Okay, FINE.
gollark: Let's just work through your thought process here, RadioRebel:1. I need a banking system!while true do 2. Nobody is giving me full code samples! The documentation is too hard! 3. Krist is too hard to use! I'll make my own, that should be simpler. 4. Nobody is giving me full code samples for this *harder* project! 5. Hmm, they're telling me to use krist, let's try that again.end
gollark: Basically, it can transmit a message to other computers, and computers wirelessly reachable by those, and so on.
