Description

Micromyrtus chrysodema is a densely branched shrub with narrowly oblong to egg-shaped leaves with the narrower end towards the base, about 1.6 mm (0.063 in) long and 0.6 mm (0.024 in) wide on a petiole 0.2–0.3 mm (0.0079–0.0118 in) long, with four to eight glands on each side of the mid-vein. The flowers are about 3.5–4.0 mm (0.14–0.16 in) in diameter, and arranged in up to four upper leaf axils on a peduncle 1.2–1.6 mm (0.047–0.063 in) long with narrowly egg-shaped bracteoles about 1.3 mm (0.051 in) long at the base. The sepals are egg-shaped, about 0.35 mm (0.014 in) long and the petals are white, round to egg-shaped and about 1.5 mm (0.059 in) long. There are five stamens, the filaments about 0.4 mm (0.016 in) long. [2]

Taxonomy

Micromyrtus chrysodema was first formally described in 2006 by Barbara Lynette Rye in the journal Nuytsia from specimens collected near Leinster in 2004. [3] The specific epithet (chrysodema) means "gold district", referring to the distribution of this species in the Western Australian Goldfields. [2]

Distribution and habitat

This species of micromyrtus grows in scrubland with mulga and Triodia in the Leinster district of the Murchison bioregion of inland Western Australia. [2] [4]

Conservation status

Micromyrtus chrysodema is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife [4] meaning that it is known from only one or a few locations that are potentially at risk. [5]
