Meiogyne is a genus of flowering plants with about 33 species [1] belonging to the family Annonaceae. It is native from southwestern India and Indochina to Australia, including Fiji and New Caledonia.
Trees or shrubs with pale straw coloured twigs. Leaves membraneous and with prominent veins. Flowers axillary, medium to large. Sepals 3, valvate, connate at base. Petals 6, valvate in two series, tapering gradually from a broad base upward and diverging, densely tomentose or sericeous-tomentose. The inner petals are slightly shorted in length with a warted patch at base inside. Stamens numerous with flat-topped slightly oblique connective tissue, concealing the anther lobes with viewed from above. Torus convex. Ovaries 2 to 5 with several ovules in two rows. Stigma discoid, sessile. Carpels thick-walled, sessile or sub-sessile.
Meiogyne is different from Cyathocalyx in several ways. The leaf texture is different. Flowers are axillary and not extra-axillary or leaf-opposed. Arrangement of the petals is diverging from a broad base and not clawed and constricted and the base is not adpressed over the stamens. The warted base of the inner petal is peculiar. The stamens and stigmas are similar to Cyathocalyx. Meiogyne is similar to Polyalthia in its spreading petals and similarity of stamens, but the large number of seeds and sessile, discoid stigma are distinguishing features. [2]
As of January 2023 [update] Plants of the World Online includes the following 33 species: [1]
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.
Goniothalamus is one of the largest palaeotropical genera 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.
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.
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.
Petenaea cordata was first described in Elaeocarpaceae and later placed in Tiliaceae, but most authors have been uncertain about its familial affinities. It was considered a taxon incertae sedis in the Angiosperm Phylogeny Group classification. Molecular analyses based on a recent collection from Guatemala indicate a distant, weakly supported sister-group relationship to the African genus Gerrardina. As no obvious synapomorphies exist for Gerrardina and Petenaea, the new monogeneric family Petenaeaceae was proposed. The polymorphic order Huerteales now comprises four small families: Dipentodontaceae, Gerrardinaceae, Petenaeaceae and Tapisciaceae. Petenaea cordata is the only species in the genus Petenaea.
Goniothalamus aurantiacus is a species of plant in the family Annonaceae. It is native to Thailand. Piya Chalermglin and Richard M.K. Saunders, the botanists who first formally described the species, named it after its orange colored inner petals.
Goniothalamus calvicarpus is a species of plant in the family Annonaceae. It is native to China, Laos and Thailand. William Grant Craib, the British botanist who first formally described the species, named it after its hairless fruit.
Goniothalamus latestigma is a species of plant in the family Annonaceae. It is native to Myanmar and Thailand. Cecil Ernest Claude Fischer, the botanist who first formally described the species, named it after its broad stigmas.
Goniothalamus maewongensis is a species of plant in the family Annonaceae. It is native to Thailand. Richard M.K. Saunders and Piya Chalermglin, who first formally described the species, named it after the Mae Wong National Park in Thailand where the type specimen was collected.
Goniothalamus repevensis is a species of plant in the family Annonaceae. It is native to Cambodia, Laos and Thailand. Achille Eugène Finet and François Gagnepain, the French botanists who first formally described the species, named it after Mt. Knang-Repeuh in Cambodia where Jean Baptiste Louis Pierre collected the lectotype specimen they examined.
Goniothalamus rotundisepalus is a species of plant in the family Annonaceae. It is native to Peninsular Malaysia and Thailand. Murray Ross Henderson, the Scottish botanist who first formally described the species, named it after its sepals which are rounded like the arc of a circle.
Goniothalamus rongklanus is a species of plant in the family Annonaceae. It is native to Thailand. Richard Saunders and Piya Chalermglin first formally described the species and named it after Phu Hin Rong Kla National Park in Thailand.
Goniothalamus tapis is a species of plant in the family Annonaceae. It is native to Peninsular Malaysia, Sumatra, and Thailand. Friedrich Anton Wilhelm Miquel, the Dutch botanists who first formally described the species, named it after a local vernacular name, Kajoe-tapis, from Pariaman Sumatra where the specimen he examined was found.
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.
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.
Wuodendron is a genus of plants in the family Annonaceae and tribe Miliuseae, containing the type and only species Wuodendron praecox. It is distributed from northeastern India north to southern China and southeast through most of Mainland Southeast Asia.
Fitzalania is a genus of flowering plants in the custard apple and soursop family Annonaceae, with all species endemic to Australia. Molecular studies show it to be a synonym of Meiogyne.
Dasymaschalon is an Asian genus of bushy plants in the subfamily Annonoideae and tribe Uvarieae. Its native range is from southern China, Indo-China to Malesia.
