Lasiopetalum, commonly known as velvet bushes, [2] is a genus of about forty-five species of flowering plants in the family Malvaceae, all endemic to Australia.

Contents

Description

Most species of Lasiopetalum are spreading or prostrate, many-branched shrubs. Commonly known as velvet bushes, they derive their common name from the pubescent (finely-furred) nature of the stems, leaves and flowers. Their leaves are generally arranged alternately on the stems. The flowerheads are either axillary or terminal. The flowers are small, the five-lobed calyces are hairy and the petals tiny. [2]

The genus is allied to the genera Guichenotia and Thomasia . The greatest diversity of species is in Western Australia, [2] where 24 species are found, of which 8 are endemic to the region. [3]

Taxonomy

The genus Lasiopetalum was first formally described in 1798 by James Edward Smith in Transactions of the Linnean Society of London . [4] [5] The genus name is derived from the Ancient Greek word lasios "hairy", and the Botanical Greek petalon "petal", and refers to the hairy calyx. [2] Lasiopetalum was previously classified in the family Sterculiaceae, however that family has been sunk into an expanded Malvaceae. Within the family, it gives its name to its tribe Lasiopetaleae, which contains about ten genera, located mostly in Australia. It is closely related to Guichenotia , although the exact relationship and genus delineation is unclear pending further research. [6]

Distribution and habitat

Species occur in lowland sclerophyll forest and heathland habitats and are endemic to Australia. [2]

Use in horticulture

The genus is rarely cultivated, although many species have flushes of attractive reddish hairy new growth, and several were cultivated in England in the 19th century. [2]

Sterculiaceae was a family of flowering plant based on the genus Sterculia. Genera formerly included in Sterculiaceae are now placed in the family Malvaceae, in the subfamilies: Byttnerioideae, Dombeyoideae, Helicteroideae and Sterculioideae.

<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 southeastern 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>Prostanthera</i> Genus of plants

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.

<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>Commersonia</i> Genus of flowering plants

Commersonia is a genus of twenty-five species of flowering plants in the family Malvaceae. Plants in this genus are shrubs or trees, occurring from Indochina to Australia and have stems, leaves and flowers covered with star-like hairs. The leaves are simple, often with irregularly-toothed edges, the flowers bisexual with five sepals, five petals and five stamens and the fruit a capsule with five valves. The genus underwent a revision in 2011 and some species were separated from Commersonia, others were added from Rulingia.

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

Thomasia is a genus of thirty-one species of flowering plants in the family Malvaceae. Plants in this genus are small shrubs that are endemic to the south-west of Western Australia, apart from P. petalocalyx that is native to Victoria and South Australia. The leaves are simple with leaf-like stipules at the base of the petiole, the flowers bisexual with five papery, petal-like sepals, usually five petals and five stamens opposite the petals. The fruit is a capsule covered with star-like hairs.

<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

Jacksonia is a genus of about forty, mostly leafless broom-like shrubs or small trees in the flowering plant family Fabaceae. The genus is endemic to Australia and species occur in a range of habitats in all Australian states except South Australia.

<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.

Species of Spyridium are found in all Australian states except Queensland.

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

Rulingia is a genus of flowering plants native to Australia and Madagascar. In 2011, all species were transferred to Commersonia with the exception of Rulingia cuneata, R. loxophylla, R.luteiflora and R. procumbens which have been transferred to the new genus Androcalva.

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

Androcalva is a genus of flowering plants in the family Malvaceae. The genus was first formally described in 2011 and comprises species formerly included in Commersonia (22) and Rulingia (4) as well as 7 new species.
