Marojejya is a genus of flowering plant in the family Arecaceae. It contains the following two species, both endemic to Madagascar: [1] [2] [3]
Hyphaene is a genus of palms native to Africa, Madagascar, the Middle East, and the Indian subcontinent.
Joseph Marie Henry Alfred Perrier de la Bâthie was a French botanist who specialized in the plants of Madagascar.
Argomuellera is a genus of plant of the family Euphorbiaceae first described as a genus in 1894. It is native to sub-Saharan Africa, Madagascar, and the Comoros Islands.
Droceloncia is a genus of plant of the family Euphorbiaceae first described as a genus in 1959. It contains only one known species, Droceloncia rigidifolia, native to Madagascar and to the nearby island of Mayotte.
Athroisma is a genus of plants in the family Asteraceae first described as a genus in 1833. It is native to East Africa and Madagascar.
Leptonema is a genus of flowering plant belonging to the family Phyllanthaceae first described in 1824. The entire genus is endemic to Madagascar. It is dioecious, with male and female flowers on separate plants.
Thecacoris is a genus of flowering plant belonging to the family Phyllanthaceae first described as a genus in 1821. It is native to tropical Africa and Madagascar. It is dioecious, with male and female flowers on separate plants, although it may rarely be monoecious.
Brachylaena is a genus of flowering plants in the aster, or composite, family, Asteraceae or Compositae. Several are endemic to Madagascar, and the others are distributed in mainland Africa, especially the southern regions.
Masoala is a genus of flowering plant in the family Arecaceae. It contains the following species, both endemic to Madagascar:
Poecilostachys is a genus of African plants in the grass family, several of the species found only in Madagascar.
Decastylocarpus is a genus of flowering plants in the family Asteraceae.
Gladiopappus is a genus of flowering plants in the family Asteraceae.
Vernoniopsis is a genus of flowering plants in the aster tribe within the sunflower family.
Oliganthes is a genus of flowering plants in the tribe Vernonieae within the family Asteraceae.
Colobanthera is a genus of flowering plants in the family Asteraceae.
The flora of Madagascar consists of more than 12,000 species of plants, as well as a poorly known number of fungi and algae. Around 83% of Madagascar's vascular plants are found only on the island. These endemics include five plant families, 85% of the over 900 orchid species, around 200 species of palms, and such emblematic species as the traveller's tree, six species of baobab and the Madagascar periwinkle. The high degree of endemism is due to Madagascar's long isolation following its separation from the African and Indian landmasses in the Mesozoic, 150–160 and 84–91 million years ago, respectively. However, few plant lineages remain from the ancient Gondwanan flora; most extant plant groups immigrated via across-ocean dispersal well after continental break-up.
Tsebona is a genus of the plant family Sapotaceae described as a genus in 1962.
Oeceoclades humbertii is a terrestrial orchid species in the genus Oeceoclades that is endemic to southeastern Madagascar, where it grows in xerophilous bush at altitudes from 500 to 600 m. It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1939 as Lissochilus humbertii and moved to the genus Eulophia in 1975 by Friedhelm Reinhold Butzin. It was last transferred to the genus Oeceoclades in 2001 by Jean Marie Bosser and Philippe Morat. The type specimen was collected from the left bank of the Manambolo valley in the Mandrare River basin in either December 1933 or January 1934 when it was recorded as flowering by its collector Jean-Henri Humbert for whom the specific epithet humbertii honors. The small pseudobulbs are conical and heteroblastic. Oeceoclades humbertii is distinguished from all other Oeceoclades by its completely green flowers. It has only been collected twice including the type specimen; the other specimen was collected by Philippe Morat in 1973 from the Onilahy valley in the Ankazoabo gorges north of Betioky.
Vernonia alleizettei is a species of flowering plant in the family Asteraceae. It is endemic to Madagascar.
Vernonia andapensis is a species of perennial plant in the family Asteraceae. It is endemic to Madagascar.
