Banksia tortifolia is a small, spreading, prostrate shrub that is endemic to the southwest of Western Australia.

It has short underground stems, pinnatipartite leaves with sharply-pointed, linear lobes on each side, greenish-cream, yellow and pink flowers in heads of about eighty, and glabrous, egg-shaped follicles.

Banksia tortifolia is a prostrate, spreading shrub with short, fire-resistant underground stems, and that typically grows to a height of 15–25 cm (5.9–9.8 in).

Meissner's description was published in Hooker's Journal of Botany and Kew Garden Miscellany as Dryandra tortifolia.

[2][3] This banksia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
