Humbertia
''Humbertia'' is a monotypic genus of flowering plants belonging to the family Convolvulaceae (morning glory family). It only contains one species, ''Humbertia madagascariensis'' Lam. It is native to Madagascar. It is known in French as ; it is endemic to southeastern Madagascar where it occurs in humid evergreen forests at altitudes up to about . The genus name (''Humbertia'') is in honour of Philibert Commerson (1727–1773), a French naturalist, best known for accompanying Louis Antoine de Bougainville on his voyage of circumnavigation in 1766–1769. The Latin specific epithet, ''madagascariensis'', means coming from Madagascar. Both genus and species were first described and published by Jean-Baptiste Lamarck in Encycl. Vol.2 on page 356 in 1786. Description ''Humbertia madagascariensis'' forms a medium-sized tree up to tall. The trunk often has small buttresses and is straight and cylindrical, up to in diameter. The outer bark is greyish-brown, with fine cracks, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convolvulaceae
Convolvulaceae (), commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato. Description Convolvulaceae can be recognized by their funnel-shaped, radially symmetrical corolla; the floral formula for the family has five sepals, five fused petals, five epipetalous stamens (stamens fused to the petals), and a two-part syncarpous and superior gynoecium. The stems of these plants are usually winding, hence their Latin name (from ''convolvere'', "to wind"). The leaves are simple and alternate, without stipules. In parasitic Cuscuta (dodder) they are reduced to scales. The fruit can be a capsule, berry, or nut, all containing only two seeds per one locule (one ovule/ovary). The leaves and starchy, tuberous roots of some species are used as foodstuffs (e.g. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philibert Commerson
Philibert Commerson (; 18 November 1727 – 14 March 1773), sometimes spelled Commerçon by contemporaries, was a French naturalist, best known for accompanying Louis Antoine de Bougainville on his voyage of circumnavigation in 1766–1769. Biography Commerson was born at Châtillon-les-Dombes in France. He studied in Montpellier, and for a time was a practicing physician. He was in contact with Carl Linnaeus, who encouraged him to study fish of the Mediterranean. Commerson returned to live at Châtillon-les-Dombes, where he occupied himself in creating a botanical garden in 1758. After the death of his wife in 1764, he moved to Paris. In 1766, Commerson joined Bougainville on his voyage of circumnavigation after being recommended for the position of naturalist by the Paris Academy of Sciences. He had previously drawn up an extensive programme of nature studies for the Marine Ministry, in which he elaborated the "three natural kingdoms" which a naturalist should investiga ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Helmet Vanga
The helmet vanga (''Euryceros prevostii'') is a distinctive-looking bird of the vanga family, Vangidae, and is classified in its own genus, ''Euryceros''. It is mainly blue-black, with rufous wings and a huge arched blue bill. It is restricted to lowland and lower montane rainforests of northeastern Madagascar. Its diet is composed of invertebrates, predominantly insects. The species is threatened by habitat loss. Taxonomy The helmet vanga is the only member of the genus ''Euryceros''. Like most vangas it was originally placed in the shrike family, Laniidae. When the ornithologist Austin L. Rand moved the majority of the vangas into a separate family in 1936, he placed the helmet vanga in its own monotypic family, Eurycerotidae. It was moved to the vanga family by J. Dorst in 1960. The closest relative within the family is believed to be the rufous vanga, which is thought to have split from the helmet vanga 800,000 years ago. The specific name ''prevostii'' commemorates the Fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Mesite
The brown mesite (''Mesitornis unicolor'') is a ground-dwelling bird endemic to Madagascar. It is one of three species in the mesite family or the Mesitornithidae, and though classified as vulnerable by the International Union for Conservation of Nature (IUCN), it is the most widespread of the three.

The upperparts of the bird are rufous brown, the underside tawny with no barring or spotting. Ecology The brown mesite is a humid forest species, it forages by walking through the forest floor flicking over leaf-litter in order to find invertebrates.
