Description

Phebalium appressum is a rounded shrub that typically grows to a height of 1 m (3 ft 3 in) and is more or less covered with silvery scales. The leaves are sessile, crowded, egg-shaped to heart-shaped, about 2 mm (0.079 in) long and 1.5 mm (0.059 in) wide and pressed against the branch. The flowers are white and borne singly or in pairs on the ends of branchlets. The pedicels are about 1 mm (0.039 in) long, thick and densely covered with rust-coloured scales. The sepals are about 1.5 mm (0.059 in) long and joined at the base and covered with rust-coloured scales on the outside. Flowering occurs in July.[2][3]

Taxonomy and naming

Phebalium appressum was first formally described in 1998 by Paul Wilson in the journal Nuytsia from a specimen collected north of Coolgardie in 1991.[2][4]

Distribution and habitat

This phebalium grows on yellow sandplain and is only known from north of Coolgardie.[2][3]

Conservation status

Phebalium appressum is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[3] meaning that it is known from only one or a few locations which are potentially at risk.[5]

gollark: And after just 20ish months and hundreds of millions of doses administered!
gollark: It seems like it's already quite bad, and this would presumably be good for the booster shots some places are talking about.
gollark: With the mRNA/viral vector vaccines, it would be pretty easy to swap out the spike protein for delta-variant ones and probably get better immunity to it, right? Is anyone doing this? It seems like a very obvious idea.
gollark: This "gematria" thing reminds me of that excellent excessively pun-heavy bible fanfiction I read but not funny.
gollark: Like the xkcd about playing conspiracy theories off against each other?
