Description

Banksia stenoprion is a prostrate shrub with short, underground, fire-resistant stems. It has leaves that are pinnatisect, V-shaped in cross-section, 120–200 mm (4.7–7.9 in) long and 3–9 mm (0.12–0.35 in) wide on a petiole 10–30 mm (0.39–1.18 in) long. There are between forty and eighty-five narrow triangular to elliptical lobes on each side of the leaves. The flowers are golden, mauve or purple, arranged in heads of between sixty and ninety with rusty-hairy involucral bracts 20–25 mm (0.79–0.98 in) long at the base of each head. The perianth is 28–35 mm (1.1–1.4 in) long and the pistil 38–41 mm (1.5–1.6 in) long. Flowering occurs from June to August and the follicles are egg-shaped, 12–15 mm (0.47–0.59 in) long and more or less glabrous.[2][3]

Taxonomy and naming

This species was first formally described in 1855 by Swiss botanist Carl Meissner who gave it the name Dryandra stenoprion and published the description in Hooker's Journal of Botany and Kew Garden Miscellany from specimens collected by James Drummond.[4][5]

In 2007 Austin Mast and Kevin Thiele transferred all dryandras to the genus Banksia and renamed this species Banksia stenoprion.[6][7]

Distribution and habitat

Banksia stenoprion occurs from Cockleshell Gully near Mount Lesueur to Badgingarra, where it grows in kwongan.

Conservation status

This banksia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[2]

gollark: That's more blueish. Turquoise, maybe.
gollark: The color corrected one looks pretty weird, I guess because it looks like you're not in water.
gollark: I said "[it] seems neat", not "yes I have definitely decided I want to do lots of this and go through a probably somewhat expensive certification/training thing".
gollark: Scuba diving seems neat. I'm doing a "discover scuba diving" thing next month (not sure exactly when, since I had my parents book it and forgot to ask...).
gollark: It looks low enough that mobile networks should still work, although in my experience you're meant to turn off phones for whatever reason.
