Epacris is a genus of about forty species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including Epacris have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus Epacris is native to eastern and southeastern Australia (southeast Queensland south to Tasmania and west to southeast South Australia), and New Zealand. The species are known as heaths or Australian heaths.
Plants in the genus Epacris are shrubs with simple leaves that are a similar colour on both surfaces and with flowers arranged singly in leaf axils near the ends of the branches, sometimes extending along the branches. Each flower is surrounded by many bracts and five, usually glabrous sepals. The petals are joined to produce a cylindrical or bell-like tube with five lobes on the end. There are five stamens which are mostly enclosed in the tube, and a single style which protrudes from the tube. The fruit is a capsule. [2]
The genus Epacris was first formally described in 1797 by Antonio José Cavanilles, who published the description in Icones et Descriptiones Plantarum. [3] Cavanilles did not specify a type species but in 1983 Edward Groesbeck Voss nominated Epacris longiflora as the lectotype. The genus name (Epacris) is derived from an Ancient Greek word meaning "on the summit", referring to habitat preference. [4]
Species of Epacris are found in all Australian states except the Northern Territory and Western Australia. Three further species are found in New Zealand. The New Zealand species E. pauciflora has been reported from New Caledonia, but this report is now regarded as an error. [5]
The following is a list of species recognised by the Australian Plant Census or by the New Zealand Plant Conservation Network as at April 2022: [6] [7]
Leucopogon is a genus of about 150-160 species of shrubs or small trees in the family Ericaceae, in the section of that family formerly treated as the separate family Epacridaceae. They are native to Australia, New Zealand, New Caledonia, the western Pacific Islands and Malaysia, with the greatest species diversity in the south-west of Western Australia. Plants in this genus have leaves with a few more or less parallel veins, and tube-shaped flowers usually with a white beard inside.
Prostanthera, commonly known as mintbush or mint bush, is a genus of about 100 species of flowering plants in the mint family Lamiaceae, and all are endemic to Australia. Plants are usually shrubs, rarely trees with leaves in opposite pairs. The flowers are arranged in panicles in the leaf axils or on the ends of branchlets. The sepals are joined at the base with two lobes. The petals are usually blue to purple or white, joined in a tube with two "lips", the lower lip with three lobes and the upper lip with two lobes or notched.
Pimelea, commonly known as rice flowers, is a genus of plants belonging to the family Thymelaeaceae. There are about 150 species, including 110 in Australia and 36 in New Zealand.
Persoonia, commonly known as geebungs or snottygobbles, is a genus of about one hundred species of flowering plants in the family Proteaceae. Plants in the genus Persoonia are shrubs or small trees usually with smooth bark, simple leaves and usually yellow flowers arranged along a raceme, each flower with a leaf or scale leaf at the base. The fruit is a drupe.
Olearia, most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple.
Pomaderris is a genus of about 80 species of flowering plants in the family Rhamnaceae, the species native to Australia and/or New Zealand. Plants in the genus Pomaderris are usually shrubs, sometimes small trees with simple leaves arranged alternately along the branches and bisexual, woolly-hairy flowers arranged in racemes or panicles. The flowers are usually yellow and often lack petals.
Rupicola was a small genus of flowering plants in the family Ericaceae. The species placed in the genus are endemic to New South Wales in Australia.
Westringia is a genus of Australian shrubs. As with other members of the mint family their upper petal is divided into two lobes. There are four stamens - the upper two are fertile while the lower two are reduced to staminodes. The leaves are in whorls of 3 or 4.
Cassinia is a genus of about fifty-two species of flowering plants in the family Asteraceae that are native to Australia and New Zealand. Plants in the genus Cassinia are shrubs, sometimes small trees with leaves arranged alternately, and heads of white, cream-coloured, yellow or pinkish flowers surrounded by several rows of bracts.
Hovea is a genus of about forty species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in this genus are sub-shrubs, shrubs or small trees with simple leaves and purple, blue or mauve flowers with a white centre. The fruit is a pod containing brown to blackish seeds. Species of Hovea occur in all Australian states, the Australian Capital Territory and the Northern Territory.
Gompholobium, commonly known as glory peas or wedge-peas, is a genus of plants in the pea family Fabaceae and is endemic to Australia. Most species have compound leaves composed of three leaflets and all have ten stamens which are free from each other and a distinctive arrangement of their sepals.
Bossiaea is a genus of about 78 species of flowering plants in the pea family Fabaceae and is endemic to Australia. Plants in this genus often have stems and branches modified as cladodes, simple, often much reduced leaves, flowers with the upper two sepal lobes larger than the lower three, usually orange to yellow petals with reddish markings, and the fruit a more or less flattened pod.
Billardiera, commonly known as appleberries, snot berries, or bluebell creepers, is a genus of flowering plants in the family, Pittosporaceae and is endemic to Australia. Plants in the genus Billardiera are woody scramblers, climbers or twiners with elliptic, lance-shaped or linear leaves arranged alternately along the stems, the flowers with petals that are joined to form a tube at the base with spreading lobes, and succulent or fleshy fruit.
Lasiopetalum, commonly known as velvet bushes, is a genus of about forty-five species of flowering plants in the family Malvaceae, all endemic to Australia.
Daviesia, commonly known as bitter peas, is a genus of about 130 species of flowering plants in the family Fabaceae, and is endemic to Australia. Plants in the genus Daviesia are shrubs or small trees with leaves modified as phyllodes or reduced to scales. The flowers are arranged singly or in groups, usually in leaf axils, the sepals joined at the base with five teeth, the petals usually yellowish with reddish markings and the fruit a pod.
Lepidosperma is a genus of flowering plant of the family Cyperaceae. Most of the species are endemic to Australia, with others native to southern China, southeast Asia, New Guinea, New Caledonia and New Zealand.
Styphelia is a genus of shrubs in the family Ericaceae, native from Indo-China through the Pacific to Australia. Most have minute or small leaves with a sharp tip, single, tube-shaped flowers arranged in leaf axils and with the ends of the petals rolled back with hairs in the inside of the tube.
