Melaleuca stereophloia | |
Melaleuca stereophloia is a plant in the myrtle family, Myrtaceae and is endemic to the south west of Western Australia. It is similar to the broombush, Melaleuca uncinata with its needle-like leaves and heads of yellow to white flowers, but its bark is hard and fibrous rather than papery .
Melaleuca stereophloia is a shrub growing to 4 m (200 in) high with hard, fibrous, grey bark. Its leaves are arranged alternately, 11–44 mm (0.4–2 in) long, 1–2.2 mm (0.04–0.09 in) wide, linear in shape, circular in cross section and tapering near the end with a hooked tip. [2] [3]
The flowers are yellow to white and arranged in heads or short spikes on the sides of the branches. Each head contains 4 to 13 groups of flowers in threes and is up to 15–17 mm (0.6–0.7 in) in diameter. The petals are 0.9–2 mm (0.04–0.08 in) long and fall off as the flower matures. There are five bundles of stamens around the flower, each with 3 to 7 stamens. Flowering occurs between August and October and is followed by fruit which are woody capsules, 1.8–2.2 mm (0.07–0.09 in) long in tight, almost spherical clusters. [2] [3]
Melaleuca stereophloia was first formally described in 1999 by Lyndley Craven in Australian Systematic Botany from a specimen collected 24 kilometres (10 mi) east of Koorda. [4] [5] The specific epithet (stereophloia) is from the Greek word stereos meaning 'hard' or 'solid', and phloios, 'bark', referring to the hard bark of this species. [2]
Melaleuca stereophloia occurs in and between the Wooramel Station, Meekatharra, Coorow and Koorda districts [2] in the Avon Wheatbelt, Carnarvon, Coolgardie, Geraldton Sandplains, Murchison, Swan Coastal Plain and Yalgoo biogeographic regions [6] where it grows in sand, clay or loam over laterite, granite or sandstone near watercourse, lakes, saltpans and saline areas. [2] [6]
Vegetation associations where M. stereophloia is the dominant species in closed shrubland near claypans are habitat for the Slender-billed thornbill, Acanthiza iredalei. [7]
Melaleuca stereophloia is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [6]
Melaleuca stereophloia leaves have a high cineole content and may therefore be useful in the production of these compounds for flavourings, medicines and insect repellant. [8]
This species coppices well and may therefore be useful in brushwood production. [8]
Melaleuca viminalis, commonly known as weeping bottlebrush, or creek bottlebrush is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales, Queensland and Western Australia. It is a multi-trunked, large shrub or tree with hard bark, often pendulous foliage and large numbers of bright red bottlebrush flowers in spring and summer. It is possibly the most commonly cultivated melaleuca in gardens and its cultivars are often grown in many countries.
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 atroviridis is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It was formerly included in the species Melaleuca uncinata but a review of that species lead to the identification of a number of new species. Like M. uncinata, this species is used for the production of brushwood fencing. It has fewer stamens in the flowers and somewhat smaller clusters of fruit but has the same needle-like leaves with a hooked end and spikes of creamy yellow flowers in early summer.
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 beardii 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. trichophylla with its purple pom-pom flower heads but unlike others, the tips of its leaves are rounded rather than pointed.
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 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 interioris is a plant in the myrtle family, Myrtaceae and is endemic to Western Australia, South Australia, Queensland, New South Wales and the Northern Territory. It was formerly included in Melaleuca uncinata and is similar to that species with its cylinder-shaped leaves and small heads of yellow flowers, but with smaller, less compressed fruiting capsules.
Melaleuca johnsonii is a plant in the myrtle family, Myrtaceae and is endemic to the south of Western Australia. It is similar to Melaleuca thapsina with its cylindrical leaves with prickly tips and usually yellow heads of flowers but is distinguished from it by its shorter leaves and papery sepals.
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 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 squamophloia is a plant in the myrtle family, Myrtaceae and is endemic to the black soil plains of south eastern Queensland in Australia. Like its close relative Melaleuca styphelioides, it is a small, erect tree with prickly leaves and spikes of cream or white flowers but its bark is hard rather than papery and the leaves have fewer veins than that species.
Melaleuca thapsina is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a prickly shrub with fibrous or papery bark, yellow to cream coloured flowers and tightly packed cylinders of fruiting capsules.
Melaleuca vinnula is a plant in the myrtle family Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with narrow leaves, heads of white to yellow flowers followed by tight clusters of fruit and it is found in the wheatbelt. It is a newly-described species from a review of the group of melaleucas known as broombrush.
Melaleuca acuminata, commonly known as mallee honeymyrtle is a plant in the myrtle family, Myrtaceae and is native to Australia and widespread in temperate areas of the continent. It is an erect shrub to about 3 m (9.8 ft) usually found in mallee woodland.
Melaleuca hamata is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It grows to a large, dense shrub with broombrush foliage and profuse pale yellow flowers in late spring.
Melaleuca acutifolia is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It has small, pointed, oval leaves and in summer, heads of white flowers. The species was originally described as a variety of Melaleuca lateriflora but was raised to species status in 2010.
Melaleuca protrusa is a shrub in the myrtle family, Myrtaceae, and is endemic to the south-west of Western Australia. It is a shrub with papery bark, narrow leaves with a hooked end and cream-coloured or yellow flowers. Although it was described as late as 2010, it is not considered a rare or endangered species. It resembles other members of the brushwood group such as M. uncinata, M. atroviridis and M. zeteticorum.
