Description

Agonis baxteri is an upright, often spindly shrub that typically grows to a height of up to 2 m (6 ft 7 in), its branchelts usually glabrous. Its leaves are dark green, elliptic to egg-shaped or narrowly so, with the narrower end towards the base, mostly 25–55 mm (0.98–2.17 in) long and 7–20 mm (0.28–0.79 in) wide, usually with three longitudinal veins. The flowers are arranged in clusters 15–25 mm (0.59–0.98 in) in diameter with hairy, grey, more or less round bracts 2.5–3.5 mm (0.098–0.138 in) long and similar bracteoles. The flowers are usually white, 12–14 mm (0.47–0.55 in) in diameter with sepals 1.8–2.5 mm (0.071–0.098 in) long, the petals 5–9 mm (0.20–0.35 in) long, and usually 23 to 32 stamens mostly 1–2 mm (0.039–0.079 in) long. Flowering mainly occurs from October to December and the fruits are in clusters 10–15 mm (0.39–0.59 in) wide. The species is superficially similar to Taxandria marginata. [2] [3] [4]

Taxonomy

In 1867, George Bentham described Melaleuca baxteri in Flora Australiensis from specimens collected by William Baxter at "King George's Sound or to the eastward". [5] [6] In 2007, Judy Wheeler and Neville Marchant changed the name to Agonis baxteri in the journal Nuytsia . [2] [7] The specific epithet (baxteri) honours the collector of the type specimens. [8]

Distribution and habitat

Agonis baxteri is found on sandplains, dunes, swamps, stony hills, disturbed and disturbed areas along the south coast in the Goldfields-Esperance region of Western Australia in the Esperance Plains and Mallee IBRA bioregions where it grows in sand and loam over quartzite, limestone or granite. [4]

Conservation status

This species is classified as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions. [4]
