Meyna is a genus of flowering plants in the family Rubiaceae.
The genus is found in tropical Asia, except for Meyna tetraphylla that occurs in northeastern tropical Africa and the Comoros.
Based on morphology, Meyna has been suggested as likely candidate for inclusion in the Canthium subgenus Canthium. [1] In 2004, a molecular phylogenetic study showed that Meyna tetraphylla is related to Canthium and the transfer to Canthium was suggested. [2]
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important species include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, some dye plants, and ornamental cultivars.
Bullockia is a genus of flowering plants in the family Rubiaceae. It was originally described as a subgenus of Canthium. The genus is distributed in eastern and southern Africa from Ethiopia to Transvaal, as well as Madagascar in bushland, woodland, savannas, and dry, deciduous forests.
Canthium is a genus of flowering plants in the family Rubiaceae. They are shrubs and small trees. The leaves are deciduous and the stems are usually thorny.
Afrocanthium keniense is a species of flowering plant in the family Rubiaceae. It is endemic to Kenya. It is threatened by habitat loss.
Keetia is a genus of flowering plants in the family Rubiaceae. It consists of climbers or scrambling shrubs, rarely small trees.
Multidentia is a genus of flowering plants in the family Rubiaceae.
Psydrax is a genus of flowering plants in the family Rubiaceae. It consists of trees, shrubs, and a few lianas in the paleotropics.
Robynsia is a monotypic genus of flowering plants in the family Rubiaceae. It was described by John Hutchinson and was named after his friend and colleague Walter Robyns. The genus contains only one species, Robynsia glabrata, which is found in Ghana, Ivory Coast and Nigeria. The species is morphologically similar to the genus Cuviera but differs by having long, slender corolla tubes.
Rytigynia is a genus of flowering plants in the family Rubiaceae. It is found in tropical and southern Africa. The genera Rytigynia and Fadogia form a strongly supported clade but neither of these genera is monophyletic.
Vangueria is a genus of flowering plants in the family Rubiaceae. The genus is named for Voa vanguer, as V. madagascariensis is known in Malagasy.
Vangueriopsis is a genus of flowering plants in the family Rubiaceae.
Vanguerieae is a tribe of flowering plants in the family Rubiaceae and contains about 640 species in 28 genera. It is one of the most species-rich groups within the family and it is distributed all over the Paleotropics.
Fadogia is a genus of flowering plants in the family Rubiaceae. The genera Rytigynia and Fadogia form a strongly supported clade but neither of these genera is monophyletic.
Afrocanthium is a genus of flowering plants in the family Rubiaceae. It consists of deciduous, unarmed trees, and shrubs. They are native to East Africa, from Sudan and Ethiopia to South Africa.
Hutchinsonia is a genus of flowering plants in the family Rubiaceae. It was described by Walter Robyns in 1928 and was named after his friend and colleague John Hutchinson. It is found in west tropical Africa.
Eriosemopsis is a monotypic genus of flowering plants in the family Rubiaceae. It was described by Walter Robyns in 1928 and no changes have been made since then. The genus contains only one species, viz. Eriosemopsis subanisophylla, which is endemic to KwaZulu-Natal, South Africa. The species is morphologically similar to the species Pygmaeothamnus zeyheri but differs by having a thick indumentum, raised venation and elliptical leaves.
Plectroniella is a monotypic genus of flowering plants in the family Rubiaceae. It was described by Walter Robyns in 1928. The genus contains only one species, i.e. Plectroniella armata, which is found in southern Mozambique and northeastern South Africa. The species is characterized by the presence of large spines and is morphologically similar to Canthium. In 2004, a molecular phylogenetic study showed that Plectroniella armata is related to Canthium ciliatum and the transfer of the genus to Canthium was suggested.
Fadogiella is a small genus of flowering plants in the family Rubiaceae. It was described by Walter Robyns in 1928.
Vangueriella is a genus of flowering plants in the family Rubiaceae. The genus is found in tropical Africa.
Cuviera is a genus of flowering plants in the family Rubiaceae native to tropical Africa. It was originally described by Augustin Pyramus de Candolle in 1807 and is named after the French naturalist Georges Cuvier.
