Banksia oblongifolia, commonly known as the fern-leaved, dwarf or rusty banksia, is a species in the plant genus Banksia. Found along the eastern coast of Australia from Wollongong, New South Wales in the south to Rockhampton, Queensland in the north, it generally grows in sandy soils in heath, open forest or swamp margins and wet areas. A many-stemmed shrub up to 3 m (9.8 ft) high, it has leathery serrated leaves and rusty-coloured new growth. The yellow flower spikes, known as inflorescences, most commonly appear in autumn and early winter. Up to 80 follicles, or seed pods, develop on the spikes after flowering. Banksia oblongifolia resprouts from its woody lignotuber after bushfires, and the seed pods open and release seed when burnt, the seed germinating and growing on burnt ground. Some plants grow between fires from seed shed spontaneously.

Banksia robur, commonly known as swamp banksia, grows in sand or peaty sand in coastal areas from Cooktown in north Queensland to the Illawarra region on the New South Wales south coast. It is often found in areas which are seasonally inundated. It grows as a multistemmed shrub to 3 m tall, with large, leathery tough green leaves with serrated margins up to 30 cm (12 in) long and 10 cm (4 in) wide. The new growth is colourful, in shades of red, maroon or brown with a dense felt-like covering of brown hairs.
