Description Banksia benthamiana is an ornamental shrub with flaky grey bark that grows to 4m in height. The leaves grow to 25cm long and 1cm wide with finely serrated leaf margins. Both surfaces of the leaf are hairy when young, becoming smoother as it matures. The yellow or orange brown flower spikes grow in late spring and summer, and are followed by woody cones with follicles. Each follicle is about 10mm to 15mm long and 5mm high. The plant does not form a lignotuber.
Habitat grows in shrubland on sandy soil, clay-loam, and gravel soils. The plant is also seen along road edges.
Distribution Banksia benthamiana is found in Western Australia between Mullewa and Kulja in scattered populations (in an area east of Geraldton and north east of Perth)
