Banksia scabrella
''Banksia scabrella'', commonly known as the Burma Road Banksia, is a species of woody shrub in the genus ''Banksia''. It is classified in the series ''Abietinae'', a group of several species of shrubs with small round or oval inflorescences. It occurs in a number of isolated populations south of Geraldton, Western Australia, with the largest population being south and east of Mount Adams. Found on sandy soils in heathland or shrubland, it grows to 2 m (7 ft) high and 3 m (10 ft) across with fine needle-like leaves. Appearing in spring and summer, the inflorescences are round to oval in shape and tan to cream with purple styles. ''Banksia scabrella'' is killed by fire and regenerates by seed.
Originally collected in 1966, ''Banksia scabrella'' was one of several species previously considered to be forms of ''Banksia sphaerocarpa'', before it was finally described by banksia expert Alex George in his 1981 revision of the genus. Like many members of the ''Abietinae'', it is rarely seen in cultivation; however, it has been described as having horticultural potential.
==Description==
''Banksia scabrella'' grows as a low shrub to 2 m (7 ft) in height and 3 m (10 ft) across, with a spreading habit. Its lateral branches are low and often rest on the ground. The small linear leaves measure 0.8 to 2.8 cm in length and 0.1 cm in width and are crowded along the stems. George recorded flowering as occurring in spring and summer (September to January),〔 but ''The Banksia Atlas'' recorded the species in bloom in April. Flowers occur in "flower spikes", or inflorescences, made up of hundreds of small flowers, or florets, densely packed around a woody axis. Quite conspicuous, they are terminal (occurring on the ends of branches) or on short side branchlets. Round or oval in shape, the cream or tan inflorescences are 3 to 6 cm (1.2–2.4 in) high and 7–9 cm (2.8–3.6 in) wide. The individual flowers are light yellow or cream, with the styles and upper floral parts purple. The perianths measure 2.7 to 3.5 cm (1–1.6 in), while the pistils 3.4 to 4.5 cm (1.6–1.8 in) in length and are curved at the apex. The inflorescences fade to grey as they age and the old flowers do not fall off. Up to 80 follicles develop on one spike, and remain closed until opened after a bushfire. Oval-shaped, they measure 1.8–2.8 cm (0.7–1.1 in) in length, by 0.5–0.9 cm (0.2–0.4 in) high, and 0.6–0.8 cm (0.2–0.3 in) wide. They open to release a dark brown oval seed 1.3–1.5 cm (0.5–0.6 in) long, 0.4–0.5 cm (0.2 in) wide with a papery dark 'wing' 1.4–2.4 cm (0.6–1 in) wide.〔 Seedlings have narrowly obovate bright green cotyledons 1.2–1.4 cm (0.5–0.6 in) long by 0.3–0.4 cm (0.1–0.2 in) wide, and the leaves which develop immediately afterward are linear and scattered, and the stem is hairy.〔
