Banksia bipinnatifida

Banksia bipinnatifida is a prostrate shrub with a lignotuber, an underground stem and only a few above-ground leaves. The leaves are bipinnatipartite, meaning that they are deeply lobed, the lobes themselves lobed, giving the impression of a bipinnate leaf. Each leaf is 70–330 mm (2.8–13.0 in) long and 30–70 mm (1.2–2.8 in) wide in outline, the lobes linear in shape, about 50 mm (2.0 in) long and the secondary lobes up to 17 mm (0.67 in) long. The edges of the leaflets are rolled under and hairy on the lower surface. The flower spikes develop on the ends of the underground stem with thirty for forty-five flowers in each spike, each flower surrounded by bracts 45–80 mm (1.8–3.1 in) long. The perianth is pink and cream-coloured to pale yellow, 40–57 mm (1.6–2.2 in) long and the pistil is 43–60 mm (1.7–2.4 in) long. Flowering occurs from October to November and the fruit is an egg-shaped follicle 17–23 mm (0.67–0.91 in) long and 13–17 mm (0.51–0.67 in) wide.

Banksia bipinnatifida occurs south from Eneabba and Mount Lesueur south to Manjimup and Busselton. Subspecies bipinnatifida grows in jarrah (Eucalyptus marginata) forest and woodland from east of Perth to Manjimup and subspecies multifida is found in kwongan in the northern part of the species' distribution.
