Eremaea purpurea is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with erect branches, small leaves and purple flowers in pairs on the ends of the branches. The fruits are woody, cup-shaped capsules which release their seeds when dry.

Description

Eremaea purpurea is a shrub growing to a height of about 1.0 metre (3 ft). The branches point upwards and the young stems are densely covered with hair. The leaves are narrow egg-shaped, tapering to a point and are 2–4.5 millimetres (0.08–0.2 in) long, 2–2.5 millimetres (0.08–0.1 in) wide and sometimes have a single vein visible on the lower surface. There are a few long, soft hairs on the upper surface and edges of the leaves. [2]

The flowers are pink to deep pink and are borne usually in pairs on the ends of the branches. They have 5 sepals which are often hairy on the outside surface and 5 petals, 4.2–4.5 millimetres (0.17–0.18 in) long. The stamens, which give the flower its colour are arranged in 5 bundles, each containing 14 to 33 stamens. Flowering occurs from December to January and is followed by fruits which are woody capsules which are 5.4–6.5 millimetres (0.2–0.3 in) long. [2]

Taxonomy and naming

Eremaea purpurea was first formally described in 1964 by Charles Gardner in Journal of the Royal Society of Western Australia. [1] The specific epithet (purpurea) is from the Latin purpureus meaning "purple". [3]

Distribution and habitat

Eremaea purpurea occurs in the Darling district in the Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain biogeographic regions. [4] It grows in sandy soils, often on roadsides and in damp depressions. [5]

Conservation

Eremaea purpurea is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [4]

<i>Eremaea</i> (plant) Genus of flowering plants

Eremaea is a genus of woody shrubs and small trees in the family Myrtaceae and is endemic to the south-west of Western Australia. Little study of the genus as a whole had been undertaken until Roger Hnatiuk researched Eremaea and published a paper in 1993, A revision of the genus Eremaea (Myrtaceae) in Nuytsia. The first species to be described was Eremaea pauciflora in 1837 and by 1964, the number of species known had increased to 12. Hnatiuk recognised 16 species, 5 subspecies and a number of varieties.

<i>Melaleuca papillosa</i>

Melaleuca papillosa is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is one of the smallest species of Melaleuca, distinguished by its narrow, usually hairy, pimply leaves, small heads of pink to purple flowers surrounded by silky hairs and scattered rather than clustered fruits.

<i>Eremaea pauciflora</i> Species of flowering plant

Eremaea pauciflora is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with small leaves and orange flowers at the ends of its branches. It has the most widespread distribution of the eremaeas with considerable variation in its characteristics so that three varieties are recognised. It was the first Eremaea to be described formally but was not originally given the name Eremaea.
