Parsonsia is a genus of woody vines in the family Apocynaceae. Species occur throughout Indomalaya, Australasia and Melanesia. [1]
The leaves are opposite, the shape and size of juvenile leaves often bearing little resemblance to the adult leaves. [2] The latex may be clear and colourless, pale yellow or milky white. [2] The flowers are green, white, cream, yellow, orange, red, pink or brown, sometimes with contrasting markings. These are followed by elongated pod-like capsules, the two follicles eventually separating to reveal numerous seeds with long, silky hairs. [2]
The genus was named and described in 1810 by botanist Robert Brown in his paper On the Asclepiadeae published in Memoirs of the Wernerian Natural History Society . [3] He named the genus in honour of James Parsons (1705–1770), an English physician and Fellow of the Royal Society. [4]
The generic name Parsonsia R.Br. (1810) is conserved against the earlier homonym Parsonsia P.Browne which was given to a genus in the family Lythraceae. The latter genus is now included in Cuphea . [5]
Parsonsia is closely related to Artia and Prestonia. [6] [7]
Accepted species [1]
A species from New Zealand, Parsonsia variablis (Variable-leaved Parsonsia), was introduced into cultivation in England in 1847 as a greenhouse plant and was noted to have a sweet scent, however the flowers were regarded as "not very showy". [18] This species is thought to be a form of Parsonsia heterophylla. [11]
Alstonia is a widespread genus of evergreen trees and shrubs, of the family Apocynaceae. It was named by Robert Brown in 1811, after Charles Alston (1685–1760), professor of botany at Edinburgh from 1716 to 1760.
Alyxia is an Australasian genus of flowering plant in the dogbane family, Apocynaceae. It contains at present 106 species, but Alyxia stellata and A. tisserantii are very variable, might be cryptic species complexes, and are need of further study. It consists of shrubby, climbing or scrambling plants. This genus occurs in China, the Himalayas, Southeast Asia, Australia, New Caledonia and the Pacific Islands. There are 14 species in Australia, 21 in New Caledonia and 7 in the other Pacific Islands, including Hawaiʻi.
Antidesma is a genus of tropical plant in the family Phyllanthaceae formally described by Linnaeus in 1753. It is native to tropical Africa, S + E + SE Asia, Australia, and various oceanic islands. The greatest diversity occurs in Southeast Asia.
Canarium is a genus of about 100 species of tropical and subtropical trees, in the family Burseraceae. They grow naturally across tropical Africa, south and southeast Asia, Indochina, Malesia, Australia and western Pacific Islands; including from southern Nigeria east to Madagascar, Mauritius, Sri Lanka and India; from Burma, Malaysia and Thailand through the Malay Peninsula and Vietnam to south China, Taiwan and the Philippines; through Borneo, Indonesia, Timor and New Guinea, through to the Solomon Islands, Vanuatu, New Caledonia, Fiji, Samoa, Tonga and Palau.
Rauvolfia is a genus of evergreen trees and shrubs, commonly known as devil peppers, in the family Apocynaceae. The genus is named to honor Leonhard Rauwolf. The genus can mainly be found in tropical regions of Africa, Asia, Latin America, and various oceanic islands.
Melodinus is a genus of plant in the family Apocynaceae, first described as a genus in 1776. It is native to Indomalaya, Meganesia and various islands in the western Pacific. A type of monoterpenoid indole alkaloids called melodinines can be isolated from Melodinus plants.
Ochrosia is a genus of flowering plants, first described in 1789. It is in the family Apocynaceae, native to Southeast Asia, Australia, and various islands of the Indian and Pacific Oceans.
Xanthostemon is a genus of plants in the myrtle family Myrtaceae, first described in 1857 by the German–born Australian botanist Ferdinand von Mueller. The genus is distributed across Malesia, Papuasia and northern Australia. The genera Pleurocalyptus and Purpureostemon from New Caledonia are morphologically close to Xanthostemon.
Zygogynum is a genus of plant in the winter's bark family Winteraceae. 19 species are native to New Caledonia, and are pollinated primarily by beetles and moths. Other species are native to New Guinea, the Bismarck Archipelago, the Solomon Islands, Lord Howe Island, and Queensland.
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.
Quintinia is a genus of about 25 evergreen trees and shrubs native to the Philippines, New Guinea, New Zealand, New Caledonia, Vanuatu and Australia. Plants have alternate leaves. White or lilac flowers form at the end of stalks or on leaf axils. The fruiting body is a capsule, usually containing a large number of tiny seeds. The genus is named after the gardener Jean-Baptiste de la Quintinie.
Rauvolfioideae is a subfamily of the flowering plant family Apocynaceae. Many species are woody lianas, others are shrubs or perennial herbs.
Coelospermum is a genus of flowering plants in the family Rubiaceae. The natural range of the genus is parts of southern China, Malesia, Papuasia, Australia and New Caledonia.
Micrechites is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1857. It is native to China, the eastern Himalayas, Southeast Asia, Papuasia, and Queensland.
Artia is a genus of plants in the family Apocynaceae first described as a genus in 1941. The entire group is endemic to New Caledonia in the SW Pacific, including the nearby Loyalty Islands. It is closely related to Parsonsia and Prestonia.
Leichhardtia is a genus of flowering plants in the dogbane family (Apocynaceae). It includes 85 species native to mainland Australia, Papuasia, New Caledonia, and Lord Howe Island.
