A herbarium is a collection of preserved plant specimens and associated data used for scientific study.
Winteraceae is a primitive family of tropical trees and shrubs including 93 species in five genera. It is of particular interest because it is such a primitive angiosperm family, distantly related to Magnoliaceae, though it has a much more southern distribution. Plants in this family grow mostly in the southern hemisphere, and have been found in tropical to temperate climate regions of Malesia, Oceania, eastern Australia, New Zealand, Madagascar and the Neotropics, with most of the genera concentrated in Australasia and Malesia. The five genera, Takhtajania, Tasmannia, Drimys, Pseudowintera, and Zygogynum s.l. all have distinct geographic extant populations. Takhtajania includes a single species, T. perrieri, endemic only to Madagascar, Tasmannia has the largest distribution of genera in Winteraceae with species across the Philippines, Borneo, New Guinea, Eastern Australia, and Tasmannia, Drimys is found in the Neotropical realm, from southern Mexico to the subarctic forests of southern South America, Pseudowintera is found only in New Zealand, and Zygogynum has species in New Guinea and New Caledonia.
Joseph Marie Henry Alfred Perrier de la Bâthie was a French botanist who specialized in the plants of Madagascar.
Armen Leonovich Takhtajan or Takhtajian, was a Soviet-Armenian botanist, one of the most important figures in 20th century plant evolution and systematics and biogeography. His other interests included morphology of flowering plants, paleobotany, and the flora of the Caucasus. He was one of the most influential taxonomists of the latter twentieth century.
René Paul Raymond Capuron was a French botanist. Capuron was responsible for an extensive amount of work on the tree flora of Madagascar. Several tree taxa with the specific epithet of capuronii honor his name, examples being Podocarpus capuronii and Schizolaena capuronii.
Adansonia perrieri, or Perrier's baobab, is a critically endangered species of deciduous tree, in the genus Adansonia. This species is endemic to northern Madagascar. It has been documented in only 10 locations, including Ankarana, Ampasindava, Loky Manambato and Montagne d'Ambre protected areas. Most populations, however, are outside of protected areas. Each location has few individuals. With an estimated population of fewer than 250 mature individuals and ongoing habitat decline due to fire and cutting for charcoal and timber or clearing for mining, this species has been assessed by IUCN as Critically Endangered. There are three species of baobab found in northern Madagascar, all sharing the common name "bozy".
Malleastrum is a genus of plants in the family Meliaceae containing 21 species native to Madagascar, Comoros and Aldabra.
Breonia is a genus of flowering plants in the family Rubiaceae. It is endemic to Madagascar. Most species are trees, rarely shrubs.
Synaphea spinulosa is a species of small shrub in the flowering plant family Proteaceae. It is endemic to Western Australia. Together with Acacia truncata, it was the first Australian endemic to be scientifically described and named, and the specimen upon which that description is based is the oldest extant specimen of an Australian plant, and very likely among the first Australian plant specimens ever collected.
René Viguier was a French botanist known for his investigations of plants within the family Araliaceae.
Schizolaena is a genus of trees and shrubs in the family Sarcolaenaceae. They are endemic to Madagascar.
Dialyceras is a genus of trees in the family Sphaerosepalaceae. The species are all endemic to Madagascar.
Perrierodendron is a genus of trees and shrubs in the family Sarcolaenaceae. They are endemic to Madagascar.
