Michelsonia
''Michelsonia'' is a genus of tree in the legume family, Fabaceae, where it is classified in the subfamily Detarioideae. It is a monotypic genus, the only species being ''Michelsonia microphylla''. It is native to the tropical rain forests of the Democratic Republic of the Congo. The wood is used locally for construction work. Description ''Michelsonia microphylla'' is a medium to large tree with a spreading crown, growing to a height of or more. The trunk is cylindrical and bare of branches for the first . It can grow to a diameter of about , the base flaring out a little and sometimes having small buttresses. The pinnate leaves are alternate and have ten to sixteen pairs of leaflets. The compound inflorescences are at the tips of the shoots and the individual flowers have white petals about long, and are followed by flat, glossy brown, woody pods up to long. These are so heavy that they sink in water. This tree is similar in appearance to '' Tetraberlinia baregarum'', with w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Endemic Flora Of The Democratic Republic Of The Congo
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Africa
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos are also trees. Trees are not a Taxon, taxonomic group but include a variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has ...

Monotypic Fabaceae Genera
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.'' ...

Rwenzori Mountains
The Ruwenzori, also spelled Rwenzori and Rwenjura, are a range of mountains in eastern equatorial Africa, located on the border between Uganda and the Democratic Republic of the Congo. The highest peak of the Ruwenzori reaches , and the range's upper regions are permanently snow-capped and glaciated. Rivers fed by mountain streams form one of the sources of the Nile. Because of this, European explorers linked the Ruwenzori with the legendary Mountains of the Moon, claimed by the Greek scholar Ptolemy as the source of the Nile. Virunga National Park in eastern DR Congo and Rwenzori Mountains National Park in southwestern Uganda are located within the range. Geology The mountains formed about three million years ago in the late Pliocene epoch and are the result of an uplifted block of crystalline rocks including gneiss, amphibolite, granite and quartzite. The Rwenzori mountains are the highest non-volcanic, non-orogenic mountains in the world. This uplift divided the pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congo Basin
The Congo Basin (french: Bassin du Congo) is the sedimentary basin of the Congo River. The Congo Basin is located in Central Africa, in a region known as west equatorial Africa. The Congo Basin region is sometimes known simply as the Congo. It contains some of the largest tropical rainforests in the world and is an important source of water used in agriculture and energy generation. The rainforest in the Congo Basin is the largest rainforest in Africa and second only to the Amazon rainforest in size, with 300 million hectares compared to the 800 million hectares in the Amazon. Because of its size and diversity, many experts have characterized the basin's forest as important for mitigating climate change because of its role as a carbon sink. However, deforestation and degradation of the ecology by the impacts of climate change may increase stress on the forest ecosystem, in turn making the hydrology of the basin more variable. A 2012 study found that the variability in precipita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cynometra Alexandri
''Cynometra alexandri'', the Uganda ironwood or muhimbi, is a species of legume that occurs in tropical lowland forests of central and east Africa. They grow gregariously in drier forest types and as a constituent of swamp forests. They reach some to in height, and larger trees often develop hollow boles and buttress roots. Taxonomy According to (2019), ''Cynometra alexandri'' along with other mainland tropical African (but not all) species of the genus ''Cynometra'' should be excluded from the genus and will be transferred to a new as yet un-named genus in the future. Distribution and habitat In Uganda it is widespread in the lowland forests (below 2,000 metres a.s.l) in the Western Rift Escarpment, where it shows a tendency toward monospecific dominance. After initial colonising, a mixed forest would contain Uganda ironwood, '' Alstonia congensis'', '' Trichilia prieuriana'', ''Khaya anthotheca'' and ''Celtis mildbraedii''.
