Description

Philotheca cymbiformis is a shrub that grows to a height of 0.1–0.5 m (3.9 in–1 ft 7.7 in) with greyish, glabrous stems. The leaves are narrow elliptical, fleshy, 6–10 mm (0.24–0.39 in) long and smooth or slightly glandular-warty. The flowers are borne singly on the ends of branchlets, each flower on a pedicel about 1.5 mm (0.059 in) long. There are five triangular sepals about 1.5 mm (0.059 in) long and five egg-shaped white petals with a reddish-brown stripe and about 6 mm (0.24 in) long. The ten stamens each that are free from each other and densely hairy near the base. Flowering occurs from September to November.[2][3]

Taxonomy and naming

This philotheca was first formally described in 1971 by Paul Wilson who gave it the name Eriostemon cymbiformis and published the description in the journal Nuytsia from specimens he collected in the Fitzgerald River Reserve.[3][4] In 1998, Wilson changed the name to Philotheca cymbiformis in the same journal.[5][6]

Distribution and habitat

Philotheca cymbiformis grows on sand in the Fitzgerald River National Park.[2]

Conservation status

This species is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[7] meaning that it is poorly known and from only one or a few locations.[8]

gollark: We don't know how many people are actually infected and sometimes the deaths get confused with other things.
gollark: We don't actually *know* what it is, and it probably varies based on... stuff, so it's not exact.
gollark: The UK is mostly-lockdowned too, and schools closed a while ago, so I basically get a 5-and-a-half-month school holiday during which I still have to do work.

gollark: There... isn't, as far as I know, a cure which has been shown to actually work.
