Alchornea Hirtella
''Alchornea hirtella'' is a shrub or small tree in the genus Alchornea in the family Euphorbiaceae. It is native to tropical Central and Southern Africa. Description ''Alchornea hirtella'' is a straggly climber, a spindly shrub or a small tree that can grow to a height of about . Distribution and habitat ''Alchornea hirtella'' is native to Central and Southern Africa. Its range extends from Senegal, Uganda and Kenya, southwards to Angola, Zambia, Mozambique and South Africa. It grows, sometimes in profusion, as an understorey shrub in tropical rain forest and in secondary forest, in riverine corridors and in the splash zone around waterfalls. It can grow at altitudes of up to . Uses Stakes made of ''Alchornea hirtella'' wood easily root and are used for bean poles. Branches are split for use in basketry and the wood is sometimes used in construction and as firewood. Extracts from the leaves of ''A. hirtella'' possess antimicrobial properties and have been found to inhibit growt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alchornea
''Alchornea'' is a plant genus of the family Euphorbiaceae first described as a genus in 1788. It is widespread in tropical and subtropical regions of Africa, South Asia, Australia, Latin America, and various oceanic islands. Molecular phylogenetic analyses suggest that ''Bocquillonia'' from New Caledonia is nested in ''Alchornea''.Wurdack, K. J., P. Hoffmann, and M. W. Chase (2005).

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as ''Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unisexual, w ...

Proteus Vulgaris
''Proteus vulgaris'' is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter. It is grouped with the Morganellaceae and is an opportunistic pathogen of humans. It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. ''P. vulgaris'' was one of the three species Hauser isolated from putrefied meat and identified (1885). Over the past two decades, the genus ''Proteus'', and in particular ''P. vulgaris'', has undergone a number of major taxonomic revisions. In 1982, ''P. vulgaris'' was separated into three biogroups on the basis of indole production. Biogroup one was indole negative and represented a new species, ''P. penneri'', while biogroups two and three remained together as ''P. vulgaris''.

Common Chimpanzee
The chimpanzee (''Pan troglodytes''), also known as simply the chimp, is a species of Hominidae, great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan (genus), ''Pan''. Evidence from fossils and DNA sequencing shows that ''Pan'' is a sister taxon to the Human evolution, human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more Robustness (morphology), robust than the bonobo, weighing for males and for females and standing . The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
