Stenopetalum (common name thread petal) [3] is a genus in the Brassicaceae family which is endemic to Australia. [4] It was first described by Robert Brown in 1821. [1] [2]
There are 11 species in the genus. [5] [6]
Plants in this genus may be annuals or perennials. They are erect, and may be with or without hairs. The sepals are saccate (shaped like a pouch or sack) and have two forms. The petals are clawed, and drawn out into long narrow apex. There are six stamens. The fruit open at maturity to release the seeds. There are four to twenty mucous seeds in each locule, arranged in two rows. [4]
The name Stenopetalum derives from the Greek, stenos, ("narrow"), and the Latin, petalum, ("petal") and describes plants in the genus as having long, narrow petals. [4]
Grevillea is a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line. It was named in honour of Charles Francis Greville, an 18th-century patron of botany and co-founder of the Royal Horticultural Society. The species range from prostrate shrubs less than 50 cm (20 in) tall to trees 35 m (115 ft) tall. Common names include grevillea, spider flower, silky oak and toothbrush plant. Closely related to the genus Hakea, the genus gives its name to the subfamily Grevilleoideae.
Hakea is a genus of about 150 species of plants in the Family Proteaceae and are endemic to Australia. They are shrubs or small trees with leaves that are sometimes flat, otherwise circular in cross section in which case they are sometimes divided. The flowers are usually arranged in groups in leaf axils and resemble those of other genera, especially Grevillea. Hakeas have woody fruit which distinguishes them from grevilleas which have non-woody fruit which release the seeds as they mature. Hakeas are found in every state of Australia with the highest species diversity being found in the south west of Western Australia.
Eriocaulon is a genus of about 400 species commonly known as pipeworts, of monocotyledonous flowering plants in the family Eriocaulaceae. The genus is widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly southern Asia and the Americas. A few species extend to temperate regions, with ca. 10 species in the United States, mostly in the southern states from California to Florida, and only two species in Canada; China has 35 species, also mostly southern. Only one species occurs in Europe, where it is confined to the Atlantic Ocean coasts of Scotland and Ireland; this species also occurs in eastern North America and is thought to be a relatively recent natural colonist in Europe. In the Americas, Eriocaulon is the only genus in its family that occurs north of Florida. They tend to be associated with wet soils, many growing in shallow water, in wetlands, or in wet savannas like flatwoods. In wet soils, their abundance appears to be related to water levels, fire frequency, and competition from other plants such as grasses. Experiments have shown that they are weak competitors compared to many other wetland plant species. Some species can persist as buried seeds during unfavorable conditions. The scientific name is derived from Ancient Greek εριον, erion, meaning 'wool', and καυλός, caulos, meaning 'stalk'.
Patersonia is a genus of flowering plants in the family Iridaceae commonly known as native iris or native flag. It was first described as a genus in 1807 by Robert Brown. It is native to Australia, New Guinea, New Caledonia, and insular Southeast Asia. The genus name is a tribute to the first Lieutenant Governor of New South Wales in Australia, William Paterson.
Baeckea is a genus of flowering plants in the myrtle family, Myrtaceae. There are about 75 species, of which 70 are endemic to Australia; the others are distributed in New Caledonia and Southeast Asia.
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.
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.
Dampiera is a genus of about 70 species of flowering plants in the family Goodeniaceae, all of which are endemic to Australia. Plants in the genus Dampiera are subshrubs or herbs with sessile leaves, flowers with five small sepals and blue, violet or pink, rarely white, two-lipped flowers.
Calothamnus is a genus of shrubs in the family Myrtaceae and is endemic to the south-west of Western Australia. The common names one-sided bottlebrush or claw flower are given to some species due to their having the flowers clustered on one side of the stem or because of the claw-like appearance of their flowers. Calothamnus species are generally medium to tall woody shrubs with crowded leaves. In most species the leaves are crowded and linear in shape, and the flowers are usually arranged in dense clusters. The petals are small and fall off the flower soon after it opens but the stamens are long, numerous and usually bright red.
Hypocalymma is a genus of evergreen shrubs in the myrtle family Myrtaceae described as a genus in 1840. The entire genus is endemic to southern Western Australia.
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.
Calocephalus is a genus of flowering plants in the aster family, Asteraceae. It is endemic to Australia, where it is represented in every state.
Maireana is a genus of around 57 species of perennial shrubs and herbs in the family Amaranthaceae which are endemic to Australia. Species in this genus were formerly classified within the genus Kochia. The genus was described in 1840 by the botanist, Moquin-Tandon and named to honour Joseph François Maire (1780-1867), an amateur botanist who befriended him during the author's first visit to Paris in 1834.
Daviesia, commonly known as Bitter-peas, is a large genus of flowering plants in the legume family. They are native to Australia, with a centre of diversity in Western Australia.
Calytrix is a genus of shrubs in the family Myrtaceae described as a genus in 1806. They are commonly known as starflowers. Calytrix are endemic to Australia, occurring in the.
Chamaescilla is a genus of Australian herbs in the subfamily Hemerocallidoideae within the asphodel family. They have grass-like basal leaves and tuberous roots. The flowers have six petals and six stamens. The seed capsules contain black, glossy seeds.
Styphelia is a genus of shrubs in the family Ericaceae and is endemic 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.
Chamaescilla corymbosa, commonly known as blue stars, blue squill or mudrurt, is a tuberous perennial herb species in the genus Chamaescilla. It is endemic to southern Australia.
Angianthus is a genus of flowering plants in the daisy family, which was first described by Wendland in 1810. The type species is Angianthus tomentosus.
