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 .

Contents

Description

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]

Taxonomy and naming

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]

Distribution and habitat

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]

Ecology

Vegetation associations where M. stereophloia is the dominant species in closed shrubland near claypans are habitat for the Slender-billed thornbill, Acanthiza iredalei. [7]

Conservation

Melaleuca stereophloia is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [6]

Uses

Essential oils

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]

Brushwood

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.

<i>Melaleuca amydra</i> Species of plant

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.

<i>Melaleuca atroviridis</i> Species of flowering plant

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.

<i>Melaleuca barlowii</i> Species of flowering plant

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.
