Henri Ernest Baillon
Henri Ernest Baillon was a French botanist and physician. He was born in Calais on 30 November 1827 and died in Paris on 19 July 1895. Baillon spent his professional life as a professor of natural history, and he published numerous works on botany. He was appointed to the Légion d'honneur in 1867 and joined the Royal Society in 1894. Baillon put together the "Dictionnaire de botanique", for which Auguste Faguet produced the wood engravings. The plant genus '' Baillonia'' (family Verbenaceae) was named in his honor by Henri Théophile Bocquillon Henri Théophile Bocquillon (5 June 1834, Crugny – 15 May 1884, Paris) was a French botanist. In Paris, he successively worked as an instructor at the Lycée Napoleon (from 1858), Lycée Louis-le-Grand (from 1862), Lycée Henri-IV (from 186 ....

Detarioideae
The subfamily Detarioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees, some of which are used for timber or have ecological importance. The subfamily consists of 84 genera, most of which are native to Africa and Asia. Pride of Burma (''Amherstia nobilis'') and tamarind (''Tamarindus indica'') are two of the most notable species in Detarioideae. It has the following clade-based definition: The most inclusive crown clade containing '' Goniorrhachis marginata'' Taub. and '' Aphanocalyx cynometroides'' Oliv., but not ''Cercis canadensis'' L., '' Duparquetia orchidacea'' Baill., or '' Bobgunnia fistuloides'' (Harms) J.

Flora Of Equatorial Guinea
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Methyl Salicylate
Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic compound with the formula C8H8O3. It is the methyl ester of salicylic acid. It is a colorless, viscous liquid with a sweet, fruity odor reminiscent of root beer, but often associatively called "minty", as it is an ingredient in mint candies. It is produced by many species of plants, particularly wintergreens. It is also produced synthetically, used as a fragrance and as a flavoring agent. Biosynthesis and occurrence Methyl salicylate was first isolated (from the plant ''Gaultheria procumbens'') in 1843 by the French chemist Auguste André Thomas Cahours (1813–1891), who identified it as an ester of salicylic acid and methanol. The biosynthesis of methyl salicylate arises via the hydroxylation of benzoic acid by a cytochrome P450 followed by methylation by a methylase enzyme. Methyl salicylate as a plant metabolite Many plants produce methyl salicylate in small quantities. Methyl salicylate levels are o ...

Domatium
A domatium (plural: domatia, from the Latin "domus", meaning home) is a tiny chamber that houses arthropods, produced by a plant. Ideally domatia differ from galls in that they are produced by the plant rather than being induced by their inhabitants, but the distinction is not sharp; the development of many types of domatia is influenced and promoted by the inhabitants. Most domatia are inhabited either by mites or ants, in what can be a mutualist relationship, but other arthropods such as thrips may take parasitic advantage of the protection offered by this structure. Domatia occupied by ants are called myrmecodomatia. An important class of myrmecodomatia comprise large, hollow spines of certain acacias such as '' Acacia sphaerocephala'', in which ants of the genera ''Pseudomyrmex'' and ''Tetraponera'' make their nests. Plants that provide myrmecodomatia are called myrmecophytes. The variety of the plants that provide myrmecodomatia, and the ranges of forms of such domatia are ...

André Aubréville
André Aubréville (30 November 1897, in Pont-Saint-Vincent (Meurthe-et-Moselle) – 11 August 1982, in Paris) was a French botanist, professor at the National Museum of Natural History, France, National Museum of Natural History in Paris and a member of the Academy of Sciences. He was the first scientist to introduce the term "desertification" (in his 1949 book: ''Climats, forêts et désertification de l'Afrique tropicale'' (Climates, Forests, and Desertification of Tropical Africa), and wrote a number of floras of former French colonies. Biography Following his service (as a youth) in the First World War, André Aubréville entered the École Polytechnique (promotion 20 "special") and obtained an engineering degree in 1922. Attracted by the botany of tropical forests, he then studied at the French National School of Forestry, École nationale des eaux et forêts in Nancy, graduating as ''Ingénieur des Eaux et Forêts des Colonies'' (Engineer of Waters and Forests of the Colo ...

Lower Guinean Forests
The Lower Guinean forests is region of coastal tropical moist broadleaf forest in West Africa, extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria and Cameroon. The Dahomey Gap, a region of savanna and dry forest in Togo and Benin, divides the Lower Guinean forests from the Upper Guinean forests to the west, which extend along the western coast of the Gulf of Guinea from Togo to Liberia and north to Guinea. To the north and northeast, the Lower Guinean forests transition to the drier inland Guinean forest–savanna mosaic and Northern Congolian forest–savanna mosaic and to the southeast by the Congolian Coastal forests, whose boundary is the Sanaga River in Cameroon.Linder, H.
