Melaleuca eurystoma is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is a small shrub with pale lemon to greenish flowers and egg-shaped to almost oval leaves.
Melaleuca eurystoma is a shrub growing to 1.5 m (5 ft) tall with mostly glabrous branches, leaves and flower parts. Its leaves are arranged alternately, 4.2–8.7 mm (0.2–0.3 in) long, 3–6.1 mm (0.1–0.2 in) wide, egg-shaped to almost oval with a wedge-shaped base and a rounded end. [1] [2]
The flowers are yellow or greenish-yellow and arranged in heads or spikes on the ends of branches which continue to grow after flowering, sometimes also on the sides of the branches. The heads are up to 25 mm (1 in) in diameter and composed of 5 to 20 individual flowers. The petals are 2.5–3.5 mm (0.098–0.14 in) long and fall off as the flower ages. There are five bundles of stamens around the flower, each with 7 to 15 stamens. Flowering occurs mainly in early spring and is followed by fruit which are woody capsules 3.5–5 mm (0.14–0.20 in) long. [1] [2]
Melaleuca eurystoma was first formally described in 1999 by Lyndley Craven in Australian Systematic Botany from a specimen collected near Tarin Rock. [3] [4] The specific epithet (eurystoma) is from the ancient Greek eurys meaning "wide" and stoma meaning "mouth", referring to the unusually wide opening of the fruit. [1]
This melaleuca occurs in and between the Lake King, Corrigin and Condingup districts [1] in the Avon Wheatbelt, Esperance Plains and Mallee biogeographic regions [5] where it grows gravelly sand and laterite. [6]
Melaleuca eurystoma is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [5]
Melaleuca pachyphylla, commonly known as wallum bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to near-coastal regions of New South Wales and Queensland in Australia. It is a medium-sized shrub with a straggling habit and red, or sometimes greenish bottlebrush flowers in summer.
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.
Melaleuca campanae is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a small, woody shrub similar to Melaleuca eulobata, with a low, spreading habit and pinkish flower heads but it has longer, pointed leaves and lacks distinct sepals which instead form a ring of tissue around the edge of the flowers.
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.
Melaleuca hnatiukii is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is a medium to large shrub with arching branches, prickly tipped leaves and creamy-white heads of flowers in spring or early summer.
Melaleuca hollidayi is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is a small shrub with fine hairs like spider web on its leaves, and bright pink flowers.
Melaleuca huttensis is a plant in the myrtle family Myrtaceae, and is endemic to the south-west of Western Australia. It is a small, woody shrub with elliptic leaves, mostly crowded near the ends of the branches which are tipped with heads of white or yellow flowes during spring and early summer. It is a threatened species, potentially endangered by the construction of the Oakajee Port near Geraldton.
Melaleuca keigheryi is a shrub in the myrtle family, Myrtaceae with white, papery bark and is endemic to the west coast of Western Australia. In spring, it has heads of pink flowers which fade in color to become white.
Melaleuca lara is a plant in the myrtle family, Myrtaceae and is endemic to a small area on the west coast of Western Australia. It is similar to Melaleuca ciliosa with its hairy young leaves and heads of yellow flowers ageing to red but there are fewer flowers in each head and the leaves are generally smaller.
Melaleuca linguiformis is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is a shrub with hairy new growth, small leaves and heads of white flowers similar to Melaleuca teuthidoides shorter sepals and more stamens in each flower.
Melaleuca monantha is a plant in the myrtle family, Myrtaceae and is endemic to an area in Queensland, Australia. It is a shrub, similar to Melaleuca minutifolia with very small leaves but the leaves lack oil glands and its flowers occur singly, rather than in pairs. It is also similar to Melaleuca sylvana but is usually multi-stemmed and has a more dense crown than that species.
Melaleuca orbicularis is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to Melaleuca cordata with its pinkish "pom-pom" heads of flowers but its leaves are smaller, almost circular compared to the heart shaped leaves of the other species.
Melaleuca procera is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is an erect, spindly shrub with cylinder-shaped leaves and heads of pinkish flowers in later spring or early summer.
Melaleuca ryeae is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. It is a small shrub, closely resembling Melaleuca amydra with its small leaves and profuse heads of pink to purple flowers but M.amydra has narrower leaves and does not have spherical clusters of fruits.
Melaleuca scalena is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. Plants of this species were previously included in Melaleuca uncinata or broombush until a review of that species in 2004. Its leaves are narrow cylinders, the flowers in small yellow heads and the fruits tightly packed together in oval clusters. This species is very similar to Melaleuca hamata but the plants have a comparatively scruffy or less strong and healthy appearance.
Melaleuca camptoclada is a shrub in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It was first described in 1990 in a review of the genus Melaleuca when the species Melaleuca laxiflora at that time was found to comprise ten species. Two of those species were new - M. camptoclada and M. ctenoides.
Melaleuca plumea is a shrub in the myrtle family, Myrtaceae, and is endemic to the south of Western Australia. It is a widely spreading, densely foliaged shrub which produces masses of deep pink flowers in spring and early summer. Fluffy hairs on parts of the flowers, including the bracts covering the flower buds, are also a feature.
Melaleuca calcicola is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It was formerly known as a subspecies of Melaleuca apodocephala but was reassessed in 2010 and raised to species status. Its branches are corky, the leaves pointed although not prickly and the flowers are creamy white, tipped with yellow.
