Bright green and brownish new growth and green follicles on spike in summer

Banksia aquilonia, commonly known as the northern banksia[2] and jingana,[3] is a tree in the family Proteaceae and is endemic to north Queensland on Australia's northeastern coastline. With an average height of 8 m (26 ft), it has narrow glossy green leaves up to 20 cm (7.9 in) long and 6 to 10 cm (2.4 to 3.9 in) high pale yellow flower spikes, known as inflorescences, appearing in autumn. As the spikes age, their flowers fall off and they develop up to 50 follicles, each of which contains two seeds.

Alex George described the plant in his 1981 monograph of the genus Banksia as a variety of B. integrifolia, but later reclassified it as a separate species. Genetic studies show it to be related to B. plagiocarpa, B. oblongifolia and B. robur. The species is found in wet sclerophyll forest and rainforest margins on sandy soils. Banksia aquilonia regenerates after bushfire by regrowing from epicormic buds under its bark. It is rarely cultivated.
