Description

Melaleuca densispicata grows to a height of 4 m (10 ft), sometimes to 5 m (20 ft). Its leaves are in alternating pairs (decussate), each leaf measuring 3–13.5 mm (0.1–0.5 in) long, 0.6–1.2 mm (0.02–0.05 in) wide, linear to narrow elliptic in shape, glabrous and lacking a stalk.

The flowers are white and arranged on a dense spike up to 40 mm (2 in) long, usually at the end of branches which continue to grow after the flowering period. Each spike contains between 5 and 24 flowers, each flower with five bundles of stamens, each bundle with 8 to 15 stamens. Flowering mainly occurs from September to December but also from February to May. The fruit are woody capsules about 2.2–2.6 mm (0.087–0.10 in) long, densely packed together.[1][2]

Taxonomy and naming

Melaleuca densispicata was first formally described by Byrnes in 1984 in Austrobaileya.[3][4] The specific epithet (densispicata) is from the Latin densus (dense) and spica (spike) referring to the flowers being close together in the inflorescence".[1]

Distribution and habitat

Melaleuca densispicata occurs in disjunct populations on the western Darling Downs in Queensland[2] and on the North West Slopes, North West Plains and Far North West Plains in New South Wales.[5] It grows on plains in low-lying areas and along stream channels in heavy clay soils.[5]
