Banksia subulata, commonly known as the awled honeypot,[2] is a species of bushy, prostrate shrub that is endemic to the southwest of Western Australia. It has long linear leaves with the edges turned under, yellowish green flowers in heads of about sixty and more or less spherical follicles.
Description
Banksia subulata is a bushy, prostrate shrub that typically grows to a width of 0.5 m (1 ft 8 in) but does not form a lignotuber. It has linear leaves that are 150–350 mm (5.9–13.8 in) long and 2–2.5 mm (0.079–0.098 in) wide on a petiole up to 1 mm (0.039 in) long and with the edges turned under. The flowers are yellowish green and arranged in heads of between sixty-five and seventy-five with many leaf-like, subulate bracts 30–80 mm (1.2–3.1 in) long and lance-shaped involucral bracts 10–12 mm (0.39–0.47 in) long at the base of the head. The perianth is 22–24 mm (0.87–0.94 in) long and the pistil 22–24 mm (0.87–0.94 in) long. Flowering occurs from September to October and the fruit is an almost spherical follicle about 11 mm (0.43 in) wide.[3][2]
Taxonomy
This species was first published as Dryandra subulata in 1964 by Charles Gardner in the Journal of the Royal Society of Western Australia from specimens he collected near the Hill River.[4][5]
In Alex George's 1996 arrangement, this species was recognised as quite distinctive, being unusual in its long, unserrated leaves, its rigid awl-shaped floral leaves, and its round follicles. With no obvious relatives, the species was placed alone in a new series named Dryandra ser. Subulatae.[6]
Since 1998,
Distribution and habitat
Banksia subulata grows in low kwongan between Eneabba and the Hill River.
Conservation status
This banksia is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[11]
