Razafimandimbisonia is a genus of flowering plants in the family Rubiaceae. It is endemic to Madagascar. [1]
The genus Alberta was shown to be paraphyletic in a phylogenetic analysis of the tribe Alberteae. The type species Alberta magna is set apart from the Malagasy Alberta species. A new genus, Razafimandimbisonia, was proposed to accommodate these Malagasy species. It is named in honour of the botanist Sylvain G. Razafimandimbison. [1]
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 genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, some dye plants, and ornamental cultivars.
Alberta is a monotypic genus of flowering plants in the family Rubiaceae. Most species have been transferred to the genus Razafimandimbisonia, except for the type species Alberta magna. It is native to KwaZulu-Natal, South Africa and is commonly known as Natal flame bush.
Psydrax is a genus of flowering plants in the family Rubiaceae. It consists of trees, shrubs, and a few lianas in the paleotropics.
Pyrostria is a genus of dioecious flowering plants in the family Rubiaceae. Most of the species are endemic to Madagascar, others occur on islands in the western Indian Ocean, a few are found in continental Africa, and only six species occur in tropical Southeast Asia. The formerly recognized genus Leroya, containing two species endemic to Madagascar, L. madagascariensis and L. richardiae, was sunk into synonymy with Pyrostria.
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.
Vanguerieae is a tribe of flowering plants in the family Rubiaceae and contains about 655 species in 30 genera. It is one of the most species-rich groups within the family and it is distributed all over the Paleotropics.
Naucleeae is a tribe of flowering plants in the family Rubiaceae and contains about 183 species in 24 genera. Species belonging to Naucleeae occur from Australasia, tropical Asia, Madagascar, tropical Africa, and to the Neotropics and North America.
Peponidium is a genus of flowering plants in the family Rubiaceae. The genus is endemic to Madagascar, except for Peponidium ovato-oblongum and Peponidium venulosum that are found on the Comoros, and Peponidium carinatum and Peponidium celastroides that are found on the Seychelles.
Danais is a genus of flowering plants in the family Rubiaceae. Most species are native to Madagascar; at least three others are distributed in Tanzania, Comoros, and the Mascarene Islands.
Payera is a genus of flowering plants in the family Rubiaceae. It was described by Henri Ernest Baillon in 1878. The genus is endemic to Madagascar.
Alberteae is a tribe of flowering plants in the family Rubiaceae and contains about 18 species in 3 genera. Its representatives are found in tropical and southern Africa and in Madagascar.
Ixoroideae is a subfamily of flowering plants in the family Rubiaceae and contains about 4000 species in 27 tribes.
Knoxieae is a tribe of flowering plants in the family Rubiaceae and contains about 131 species in 16 genera. Its representatives are found in Tropical and Southern Africa, the islands in the Western Indian Ocean, the Arabian Peninsula, Tropical and Subtropical Asia, and Northern Australia.

Sabiceeae is a tribe of flowering plants in the family Rubiaceae and contains about 164 species in 7 genera. Its representatives are found in tropical Africa, Madagascar, Sri Lanka, and from Mexico to tropical America. The genus Sabicea is one of the rare genera in Rubiaceae that occurs both in tropical Africa and tropical America.
Psychotrieae is a tribe of flowering plants in the family Rubiaceae and contains about 2114 species in 17 genera. Its representatives are found in the tropics and subtropics.
