Calytrix is a genus of about 83 species of flowering plants, commonly known as star flowers, [2] in the family Myrtaceae and is endemic to Australia. Plants in the genus Calytrix are small to large shrubs with small, spreading and more or less round leaves, the flowers arranged singly in leaf axils. The flowers are bisexual with 5 overlapping sepals with a long awn, and many stamens.

Description

Plants in the genus Calytrix are dwarf to large shrubs with overlapping or widely-spaced leaves, but with stipules absent or small. The flowers are arranged singly in leaf axils with 2 bracteoles at the base. The floral tube is usually long and tube-shaped with 5 overlapping sepals with a long awn on the end and 5 lance-shaped to elliptic petals that are free from each other and fall from the flower as it develops. There are many stamens, in one to several whorls. The fruit is a small, dry nut containing a single seed. [2] [3] [4] [5] [6] [7]

Taxonomy

The genus Calytrix was first formally described in 1806 by Jacques Labillardière in his Novae Hollandiae Plantarum Specimen , and the first species he described (the type species was Calytrix tetragona . [8] [9] The genus name (Calytrix) means "calyx hair", referring to the sepal awns. [10]

Distribution

Calytrix are endemic to Australia, occurring in the Northern Territory, Queensland and South Australia, but the majority of species occur in the south-west of Western Australia. [3]

<span class="mw-page-title-main">Myrtaceae</span> Myrtle family of plants

Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire. The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous.

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

Darwinia, sometimes commonly known as mountain bells or simply bells, is a genus of about 70 species of evergreen shrubs in the family Myrtaceae, endemic to southeastern and southwestern Australia. The majority are native to southern Western Australia, but a few species occur in South Australia, New South Wales and Victoria. The genus was named in honour of Erasmus Darwin, grandfather of Charles Darwin by Edward Rudge in 1816. Most darwinias grow to a height of between 0.2 and 3 m, and many are prostrate shrubs. Most have small, simple leaves and the flowers are often grouped together, each flower with five red, white or greenish petals and ten stamens. In many species, the flowers are surrounded by large, colourful bracts, giving rise to their common names.

<i>Leucopogon</i> Genus of flowering plants

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.

<i>Pimelea</i> Genus of flowering plants

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.

<i>Olearia</i> Genus of flowering plants

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.

<i>Kunzea</i> Genus of flowering plants

Kunzea is a genus of plants in the family Myrtaceae and is endemic to Australasia. They are shrubs, sometimes small trees and usually have small, crowded, rather aromatic leaves. The flowers are similar to those of plants in the genus Leptospermum but differ in having stamens that are longer than the petals. Most kunzeas are endemic to Western Australia but a few occur in eastern Australia and a few are found in New Zealand. The taxonomy of the genus is not settled and is complicated by the existence of a number of hybrids.

<i>Baeckea</i> Genus of flowering plants

Baeckea is a genus of flowering plants in the myrtle family, Myrtaceae, all but one endemic to Australia. Plants in the genus Baeckea are shrubs or small trees with leaves arranged in opposite pairs, white to deep pink flowers with five sepals and five petals, and five to fifteen stamens that are shorter than the petals.

<i>Hovea</i> Genus of legumes

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.

<i>Mirbelia</i> Genus of legumes

Mirbelia is a plant genus belonging to the family Fabaceae and is endemic to Australia, occurring in every mainland state except South Australia. Plants in the genus Mirbelia are prickly, perennial shrubs with simple, sometimes sharply-pointed leaves, or the leaves absent. The flowers are arranged singly or in groups in leaf axils or on the ends of branches, the sepals joined at the base with five teeth. The petals are usually red, orange, purplish or bluish and the fruit is an inflated pod.

<i>Gompholobium</i> Genus of legumes

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.

<i>Cryptandra</i> Genus of flowering plants

Cryptandra is a genus of flowering plants in the family Rhamnaceae and is endemic to Australia. Most plants in the genus Cryptandra are spiny, heath-like shrubs with small, clustered leaves and flowers crowded at the ends of branches, the flowers are usually small, surrounded by brown bracts, and with tube-shaped hypanthium, the petals hooded over the anthers.

<i>Thryptomene</i> Genus of flowering plants

Thryptomene is a genus of flowering plants in the family Myrtaceae and is endemic to Australia. Plants in the genus Thryptomene are shrubs with small leaves arranged in opposite pairs and white or pink flowers. About forty-seven species of Thryptomene, occurring in all Australian states and the Northern Territory, have been formally described.

<i>Jacksonia</i> (plant) Genus of legumes

Plants in the genus Micromyrtus are shrubs with simple leaves arranged in opposite pairs, and white, pink or yellow flowers arranged in upper leaf axils, the flowers with five sepals five petals and five or ten stamens.

<i>Bossiaea</i> Genus of legumes

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.

<i>Daviesia</i> Genus of plants

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.
