Bolusiella Iridifolia
''Bolusiella iridifolia'' is a species of flowering plant in the family Orchidaceae. It is widespread across much of tropical and southern Africa, as well as the Comoro Islands in the Indian Ocean. ''Bolusiella iridifolia'' grows in a cold windy humid environment at high altitudes. The species has succulent leaves that form a fan shape. The inflorescence is periodically covered in brown bracts from which protrude tiny white spurred flowers. Subspecies Two subspecies are recognized: *''Bolusiella iridifolia ''subsp''. iridifolia'' - from Ivory Coast east to Ethiopia and Tanzania, south to Angola and Zimbabwe; also Comoros *''Bolusiella iridifolia ''subsp''. picea'' P.J.Cribb - from Burundi and Kenya south to Zimbabwe file:Zimbabwe, relief map.jpg, upright=1.22, Zimbabwe, relief map Zimbabwe, officially the Republic of Zimbabwe, is a landlocked country in Southeast Africa, between the Zambezi and Limpopo Rivers, bordered by South Africa to the south, Bots ...

List Of Orchidaceae Genera
This is a list of genera in the orchid family (Orchidaceae), originally according tThe Families of Flowering Plants- L. Watson and M. J. Dallwitz. This list is adapted regularly with the changes published in the ''Orchid Research Newsletter'' which is published twice a year by the Royal Botanic Gardens, Kew. The most up to date list of accepted genera, natural nothogenera, species and natural nothospecies with their synonyms can be found on the World Checklist of Selected Plants FamilieSearch Pageand Plants of the World Online published by the Royal Botanic Gardens, Kew. This list is reflected on Wikispecies Species:Orchidaceae, Orchidaceae and the new eMonocot websitOrchidaceae Juss. This Taxonomy (biology), taxonomy undergoes constant change, mainly through evidence from DNA study. Orchids were traditionally defined by morphological similarity (structure of their flowers and other parts). However, recent changes to nomenclature have been driven primarily by DNA studies and also by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchidaceae
Orchids are plants that belong to the family (biology), family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan distribution, cosmopolitan plants that are found in almost every habitat (ecology), habitat on Earth except glaciers. The world's species richness, richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla (genus), Vanilla'' (the genus of the Vanilla planifolia, vanilla plant), the type genus ''Orchis'', and many commonly cultivated plants s ...

Sub-Saharan Africa
Sub-Saharan Africa is the area and regions of the continent of Africa that lie south of the Sahara. These include Central Africa, East Africa, Southern Africa, and West Africa. Geopolitically, in addition to the list of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations geoscheme for Africa, United Nations (UN). This is considered a non-standardised geographical region with the number of countries included varying from 46 to 48 depending on the organisation describing the region (e.g. United Nations, UN, World Health Organization, WHO, World Bank, etc.). The Regions of the African Union, African Union (AU) uses a different regional breakdown, recognising all 55 member states on the continent—grouping them into five distinct and standard regions.

Comoro Islands
The Comoro Islands are a group of volcanic islands in the Mozambique Channel, an arm of the Indian Ocean lying between Madagascar and the African mainland. Three of the islands form the Union of the Comoros, a sovereign nation, while Mayotte belongs to France. Geography The Comoro Islands are located in the Mozambique Channel to the north-west of Madagascar and facing Mozambique. These volcanic islands, covering a total area of 2034 km2, are as follows: * Grande Comore, Ngazidja (also known as ''Grande Comore''): the largest island of the Union of the Comoros, with its capital Moroni, Comoros, Moroni * Anjouan, Ndzuwani (also known as ''Anjouan''): part of the Union of the Comoros * Mohéli, Mwali (also known as ''Mohéli''): part of the Union of the Comoros * Mayotte (also known as ''Maore''): a French overseas department. Mayotte is composed of two islands, Grande-Terre (Mayotte), Grande-Terre and Pamanzi, Petite-Terre (also known as ''Pamanzi''), where the Dzaoudzi–Pa ...

Monopodial
Vascular plants with monopodial growth habits grow upward from a single point. They add leaves to the apex each year and the stem grows longer accordingly. The word ''Monopodial'' is derived from Greek language, Greek '', ''one'' and '', "foot", in reference to the fact that monopodial plants have a single trunk or stem. Orchidaceae, Orchids with monopodial growth often produce copious aerial roots that often hang down in long drapes and have green chlorophyll underneath the grey root coverings, which are used as additional photosynthetic organs. They do not have a rhizome or pseudobulbs so species adapted to dry periods have fleshy Succulent plant, succulent leaves instead. Flowers generally come from the stem between the leaves. With some monopodial species, the stem (the rhizome) might fork into two, but for all monopodial orchids this is not necessary for continued growth, as opposed to orchids with sympodial growth.''The Orchid Expert'', Dr. D. G. Hessayon, Expert Books, Transw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
