Cyathocalyx is a small genus with about 22 species distributed from southern India, Sri Lanka, through Malaysia, Indomalayan islands and reaches as far as Fiji in the South Pacific. [1]
The salient features of the genus includes- monopodial trees, supra-axillary or nearly leaf-opposed inflorescences, six petals which are basally concave and constricted above the reproductive organs to form a "pollination chamber".
The genus consists 22 identified species with two unresolved species. [2]
The Annonaceae are a family of flowering plants consisting of trees, shrubs, or rarely lianas commonly known as the custard apple family or soursop family. With 108 accepted genera and about 2400 known species, it is the largest family in the Magnoliales. Several genera produce edible fruit, most notably Annona, Anonidium, Asimina, Rollinia, and Uvaria. Its type genus is Annona. The family is concentrated in the tropics, with few species found in temperate regions. About 900 species are Neotropical, 450 are Afrotropical, and the remaining are Indomalayan.
Alphonsea is a genus of plant in the family Annonaceae. As of April 2014 The Plant List recognises 38 accepted species:
Goniothalamus is one of the largest palaeotropical genera of plant in family Annonaceae.
Miliusa is a genus of plant in family Annonaceae. Species have been recorded from tropical & subtropical Asia to N. Australia.
Phaeanthus is a genus of plant in family Annonaceae.
Polyalthia is a genus of flowering plants in the family Annonaceae. There are approximately 90 species distributed from Africa to Asia and the Pacific.
Pseuduvaria is a genus of the plant family Annonaceae and tribe Miliuseae: with a native range is Tropical Asia.
Trivalvaria is a genus of plant in family Annonaceae. It is found in Tropical Asia including Hainan.
Xylopia is a genus of flowering plants in the family Annonaceae. They are mostly trees and some shrubs. There are about 160 species distributed in Asia, Africa, and the Americas.
Meiogyne is a genus of flowering plants with about 28 species belonging to the family Annonaceae. It is native from southwestern India and Indochina to Australia, including Fiji and New Caledonia.
Artabotrys is a genus of plants in the Annonaceae family. There are over 100 species in the Old World tropics, with 31 species in Africa. It is part of the custard apple family (Annonaceae). All species are small trees or shrubs with a tendency to climb. Leaves are simple and alternate, without hairs. Bisexual flowers are borne singly or in clusters opposite the leaves. The 6-petalled flowers are scented, and the plant bears fleshy fruits.
Huberantha is a genus of plants in the family Annonaceae and tribe Miliuseae. It is distributed in Australia, tropical Asia, East Africa and some Pacific islands. Tanawat Chaowasku named the genus "Huber's flowers" in honor of the German botanist Herbert Huber and to highlight its flowers as a distinguishing feature of the genus. A number of species have been moved here from the genus Polyalthia.
Mitrephora maingayi is a species of plant in the family Annonaceae. It is native to Bangladesh, Borneo, Cambodia, Laos, Peninsular Malaysia, Myanmar, Sumatra, and Vietnam. Joseph Hooker and Thomas Thomson, the British botanists who first formally described the species, named it in honor of Alexander Carroll Maingay, the British botanist who collected the specimen they examined.
Monoon is a genus of plants in the family Annonaceae and the tribe Miliuseae. Species have been recorded from the Indian subcontinent, Indo-China, Malesia, New Guinea and Australia, with introductions in West Africa. A number of species have been moved here from the genus Polyalthia.
The Malmeoideae are a subfamily of trees and other plants of the family Annonaceae.
Friesodielsia is a genus of flowering plants in the custard apple and soursop family Annonaceae, with all species found in the Old World, mostly in the tropics. A molecular study shows that Friesodielsia should be more narrowly circumscribed, with the only species remaining being the Asian ones, which can also be distinguished by their possession of globose or ellipsoid monocarps, and six petals per flower arranged in two whorls.
Monocarpia is an Asian tree genus in the family Annonaceae and the monotypic tribe Monocarpieae. Its native range is Borneo, peninsular Malaysia and Sumatera.
Drepananthus is a genus of flowering plants belonging to the family Annonaceae.
