Description

Banksia meganotia is a shrub that typically grows to a height of 0.3–1 m (1 ft 0 in–3 ft 3 in) and forms a lignotuber. It has linear, pinnatipartite leaves that are 30–70 mm (1.2–2.8 in) long and 10–25 mm (0.39–0.98 in) wide on a petiole 5–10 mm (0.20–0.39 in) long with between six and ten sharply-pointer, linear lobes on each side. The flowers are yellow and arranged in a head with egg-shaped to lance-shaped involucral bracts 17–20 mm (0.67–0.79 in) long at the base of the head. The flowers have a perianth 22–23 mm (0.87–0.91 in) long and a hairy pistil 26–30 mm (1.0–1.2 in) long. Flowering occurs in October and the follicles that follow flowering are about 5 mm (0.20 in) long.[2][3][4]

Taxonomy and naming

This species was first formally described in 1996 by Alex George in the journal Nuytsia from specimens he collected in the Dongolocking Nature Reserve, and was given the name Dryandra meganotia.[4][5] In 2007, Austin Mast and Kevin Thiele transferred all the dryandras to the genus Banksia and this species became Banksia meganotia.[6][7] The specific epithet (meganotia) is from ancient Greek words meaning "large" and "southern" referring to the Great Southern region of Western Australia, where this species occurs.[4]

Distribution and habitat

Banksia meganotia mainly grows in kwongan between Kulin and Nyabing in the Avon Wheatbelt and Mallee biogeographic regions.[3]

Ecology

An assessment of the potential impact of climate change on this species found that it was likely to be driven to extinction by loss of habitat by 2080, even under mild climate change scenarios.[8]

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.[9]

gollark: Oh, and if for some reason you're an *incredibly* self-confident person who thinks all acts they do are right, you'll turn out maximally non-evil.
gollark: Being vaguely aware of that sort of thing, and also that I live in a relatively comfortable position in what is among the richest societies ever, I feel bad about *not* doing more things, which would cause me to be more evil than someone who just ignores this issue forever, which is not, according to arbitrary moral intuitions I have™, something which an evilness measuring thing should say.
gollark: With any actual planning you can just give away as much as reasonably possible. It's just an issue of good management of stuff.
gollark: There are *not* that many people who actually go to the logical conclusion of that line of thinking and go "guess I'll donate all my excess income to charities".
gollark: It would be bad for you and you could argue that not doing so maximizes long-run donation, but you aren't actually maximizing that either.
