Hakea trifurcata

The shrub has two forms of leaves usually needle-like, curved, straight or may be divided in segments, 2.2–7.5 cm (0.87–2.95 in) long and 0.8–1.3 mm (0.031–0.051 in) wide, grooved below and ending in a sharp point.

The second form is wider, oblong to egg-shaped 2–5 cm (0.79–1.97 in) long, 6–19 mm (0.24–0.75 in) wide with a central vein and is either wedge-shaped at the apex or narrows gradually.

The inflorescence consists of between one and ten sweetly, strongly scented cream, white or pink flowers often with red styles.

The green fruit are smooth, obliquely egg-shaped and appear to resemble flat leaves, 1.5–2.5 cm (0.6–1 in) long and 0.5–0.8 mm (0.020–0.031 in) wide.

Trials were conducted at the Perth Zoo to determine whether the broad leaves deterred granivores from foraging the fruit by the short-billed black cockatoo (Calyptorhynchus funereus latirostris) .

[5] This species grows in fire-prone locations and does not resprout after fire, therefore continued populations require a "seed bank" to maintain numbers.
