Melaleuca subtrigona is a plant in the myrtle family, Myrtaceae, and is endemic to the south-west of Western Australia. It is a small shrub with warty leaves and heads of "pom-pom" flowers in spring and early summer.
Melaleuca subtrigona is a shrub which grows to a height of 1 m (3 ft) with branches that are covered with fine hairs. Its leaves are arranged alternately, 2.5–10.5 mm (0.1–0.4 in) long and 0.7–1.2 mm (0.03–0.05 in) wide. They are covered with fine, silky hairs, are linear to narrow oval shaped, oval in cross section and have distinct, slightly raised oil glands. [2]
The flowers are a shade of pink to purple and are arranged in heads on the ends of branches which continue to grow after flowering. The heads contain 2 to 6 groups of flowers in threes and are up to 16 mm (0.6 in) in diameter. The stamens are arranged in five bundles around the flowers and each bundle contains 3 to 7 (but mostly 3) stamens. Flowering occurs between August and January and is followed by fruit which are woody capsules 2.5–4 mm (0.1–0.2 in) long in loose clusters. [2] [3]
Melaleuca subtrigona was first formally described in 1844 by Johannes Conrad Schauer in Plantae Preissianae . [4] [5] The specific epithet (subtrigona) is from the Ancient Greek word trigonos meaning triangular [6] :814 and the prefix sub- meaning “under” [6] :826 referring to the shape of the leaves as being almost triangular in cross-section. [2]
Melaleuca sieberi occurs in and between the Brookton, Stirling Range and Ravensthorpe districts [2] in the Avon Wheatbelt, Esperance Plains, Jarrah Forest, Mallee and Swan Coastal Plain biogeographic regions. [7] It grows in sand, clay and laterite on sandplains and hills. [8]
This species is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [7]
Melaleuca preissiana, commonly known as stout paperbark, modong or moonah, is a plant in the myrtle family, Myrtaceae and is endemic to coastal areas of southwest Australia. It is a shrub or small tree with papery bark, small leaves and spikes of usually white flowers. It occurs chiefly in areas that are seasonally wet.
Melaleuca rhaphiophylla, commonly known as swamp paperbark is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. It has narrow, needle-like leaves and profuse spikes of white or yellowish flowers at variable times throughout the year. As its common name suggests, it is usually found in salt marshes, or swamps or along watercourses and occurs over wide areas of the south-west.
Melaleuca amydra is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to Melaleuca ryeae with its small, compact form, oval leaves and "pom-pom" heads of pink to purple flower heads on the ends of the branches in spring.
Melaleuca barlowii is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to a number of other Western Australian melaleucas such as M. conothamnoides with its purple pom-pom flower heads but is a more erect shrub with different leaves and the fruiting clusters have a different shape.
Melaleuca boeophylla is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to a number of other Western Australian melaleucas such as M. filifolia with its purple pom-pom flower heads but its leaves are shorter and oval in cross-section.

It is similar to a number of other Western Australian melaleucas such as M. pentagona with its purple pom-pom flower heads but it is a smaller shrub with narrower leaves and smaller inflorescences.
Melaleuca carrii is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small shrub similar to Melaleuca pentagona, with "pom-pom" heads of pinkish flowers and sharply pointed leaves but it is generally smaller, lacks a groove in its leaves and retains its petals on the flowers for longer than that species.
Melaleuca clavifolia is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small shrub similar to Melaleuca tinkeri, with "pom-pom" heads of pinkish flowers and soft, silky hairs on the new growth but it has larger flower heads and its leaves are shorter, more club-shaped and have less distinct oil glands.

It is an erect shrub with narrow leaves, pinkish or purple flowers and small fruit, and is similar to Melaleuca tuberculata except that it lacks brown bracts at the base of the flowers.

Melaleuca micromera, commonly known as wattle honey-myrtle, is a plant in the myrtle family Myrtaceae and is endemic to a small area in the south-west of Western Australia. It is a rare species with unusual foliage and profuse small yellow flowerheads, making it a plant that is suitable for cultivation, if only to protect it from extinction.
Melaleuca parviceps, commonly known as rough honey-myrtle is a shrub in the myrtle family, Myrtaceae, and is endemic to the south-west of Western Australia. It is a shrub with varying shades of pink or purple flowers, the stamens tipped with yellow anthers. In describing it, John Lindley noted: "every twig ... is terminated by hemispherical heads of brilliant pink". It is similar to Melaleuca manglesii and Melaleuca seriata.
