Description
Melaleuca microphylla is a dense, rounded shrub growing to about 4–5 m (10–20 ft) high with glabrous foliage and grey or white papery bark. The leaves are arranged alternately, 3–8 mm (0.1–0.3 in) long, 0.3–0.5 mm (0.01–0.02 in) wide, linear to narrow lance-shaped and with a blunt or slightly pointed end.
The flowers are white to creamy yellow and are arranged in small heads on the ends of the branches which continue to grow after flowering. The heads are up to 50 mm (2 in) long, 22 mm (0.9 in) in diameter and contain between 10 and 50 individual flowers. The petals are 1.0–2.2 mm (0.04–0.09 in) long and fall off as the flower matures. The stamens are arranged in five bundles around the flowers with 4 to 10 stamens in each bundle. The main flowering season is spring and is followed by fruit which are woody, cup-shaped capsules, 2–3 mm (0.08–0.1 in) long and 3–4 mm (0.1–0.2 in) in diameter, arranged in loose clusters along the stem.
Taxonomy and naming
This species was first formally described in 1812 by James Edward Smith in The Cyclopedia from a specimen "gathered near King George's Sound, on the West Coast of New Holland, by Mr. A. Menzies". The specific epithet (microphylla) is from the Latin word microphyllus meaning “having very small leaves”.
Distribution and habitat
Melaleuca microphylla occurs in and between the Manjimup and Manypeaks districts in the Esperance Plains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren biogeographic regions. It grows in sandy clay near swamps and creeks.
Conservation
Melaleuca micromera is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.
Horticulture
This species is often used as a hedge or screen, growing successfully in most soils and situations.
Essential oils
The oil from the leaves of this species consists mainly of monoterpenes.
