Cremastosperma is a genus of flowering plants in the family Annonaceae, subfamily Malmeoideae, tribe Malmeae. [1] In 2018 there were 34 recognised species distributed in Central and South America. [2]
Cremastosperma was described by Robert Elias Fries in 1930, [3] based on Aberemoa pedunculata Diels, originally described by Ludwig Diels (1906), [4] which thus became the type species Cremastosperma pedunculatum (Diels) R.E.Fr..
Species of Cremastosperma are found in lowland to pre-montane tropical forest in the Neotropics. [5] The greatest species diversity is distributed in the narrow tropical zone to the west of the Andean mountain chain on the Pacific Ocean side of north-western South America, north into Central America [6] as far as Costa Rica; [2] and on the eastern side of the Andes extending from Colombia through eastern Ecuador and Peru as far south as Bolivia. Two species are found in coastal Venezuela (Cremastosperma macrocarpum Maas and Cremastosperma venezuelanum Pirie), [7] and one in French Guiana (Cremastosperma brevipes (DC.) R.E.Fr.).
Cremastosperma species are small understory trees with typical Annonaceae floral morphology (sepals and petals in whorls of three; indefinite numbers of spirally arranged stamens and carpels) bearing a resemblance to various other Neotropical genera with apocarpous, single-seeded, stipitate fruits (such as Guatteria ). The most useful character by which they can be distinguished from these and other similar Neotropical Annonaceae is displayed by the midrib of the leaves, which is raised on the upper side with an unusual, mostly conspicuous, longitudinal groove.
Recognised species:
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.
Sapranthus is a genus of flowering woody plants in the family Annonaceae. The genus was first described in 1866 by Berthold Carl Seemann.
Anaxagorea is a genus of flowering plants in the subfamily Anaxagoreoideae in the family Annonaceae. There are about 26 species, distributed in Central and South America.
Guatteria ferruginea is a species of plant in the Annonaceae family. It has a South American distribution from Suriname and French Guiana until the Atlantic Forest of Brazil.
Klarobelia is a genus of flowering plants in the family Annonaceae. There are about 12 species.
Mosannona is a genus of flowering plants in the family Annonaceae. There are about 14 species native to the Neotropics, distributed from Mexico through Central America and South America particularly in rainforest surrounding the Andes.
Pseudoxandra williamsii is a species of plant in the Annonaceae family. It is endemic to Peru. Robert Elias Fries, the Swedish botanist who first formally described the species using the basionym Cremastosperma williamsii, named it after Llewelyn W. Williams, the Welsh economic botanist, who collected the holotype specimen he examined.
Uvariopsis is a genus of flowering plants in the family Annonaceae. The genus is unique to Africa, and consists of about 18 species, all of which are either ramiflorous, cauliflorous or both.
Lyndley Alan Craven was a botanist who became the Principal Research Scientist of the Australian National Herbarium.
Duguetia is a genus of trees and shrubs in the plant family Annonaceae with approximately 90 species in central and South America, and four species in west Africa.
Aspidistra umbrosa is a species of flowering plant. Given it was described from an unclassified Aspidistra specimen from another study, neither its distribution nor habitat are known.
Kathleen Anne Kron is a retired biology professor from Wake Forest University. She is known for her research on Ericaceae, a family of flowering plants.
Cremastosperma yamayakatense is a species of tropical tree in the "soursop" family Annonaceae that is found in lowland rainforest in the Amazonas Region of northern Peru.
Cremastosperma cauliflorum is a species of plant in the family Annonaceae. It is native to Brazil, Colombia, Ecuador and Peru. Robert Elias Fries, the Swedish botanist who first formally described the species, named it after its flowers which grow from its main trunk or stem.
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.
Pseudoxandra leiophylla is a species of plant in the family Annonaceae. It is native to Brazil, Colombia, and Venezuela. Ludwig Diels, the German botanist who first formally described the species using the basionym Unonopsis leiophylla, named it after its smooth leaves.
Pseudoxandra lucida is a species of plant in the family Annonaceae. It is native to Bolivia, Brazil, Colombia, Peru, and Venezuela. Robert Elias Fries, the Swedish botanist who first formally described the species, named it after its shiny leaves.
Pseudoxandra polyphleba is a species of plant in the family Annonaceae. It is native to Bolivia, Brazil, Colombia, French Guiana, Guyana, and Peru. Ludwig Diels, the German botanist who first formally described the species using the basionym Unonopsis polyphleba, named it after the distinctive veins in its leaves.
The Malmeoideae are a subfamily of trees and other plants of the family Annonaceae.
Ephedranthus is a genus of flowering plants belonging to the family Annonaceae.
