Melaleuca microphylla is a dense, rounded shrub growing to about high with
glabrous foliage and grey or white papery bark. The leaves are arranged alternately, long, 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 long, in diameter and contain between 10 and 50 individual flowers. The petals are 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, long and in diameter, arranged in loose clusters along the stem. ==Taxonomy and naming==
