Dendrosenecio Meruensis
''Dendrosenecio meruensis'' is one of the East African giant groundsel, this one is endemic to the slopes of Mount Meru.

Arthur Disbrowe Cotton
Arthur Disbrowe Cotton, OBE (15 January 1879 – 27 December 1962) was an English plant pathologist, mycologist, phycologist, and botanist. A.D. Cotton was born in London and educated at King's College School and the Royal College of Science, where he completed a degree in botany in 1901. He became a demonstrator there and subsequently at Owens College, Manchester, where he developed an interest in fungi, undertaking research into orchid mycorrhizas. In 1904 he was appointed assistant to George Massee, head of mycology and cryptogamic plants at the Royal Botanic Gardens, Kew. Cotton remained at Kew till 1915, officially working on algae, but also making time to pursue his particular interest in clavarioid fungi. During this time Cotton collaborated with Elinor Francis Vallentin. Vallentine supplied Cotton with numerous specimens enabling him to undertake the first comprehensive study of Cryptogams from the Falkland Islands. In 1915 he took charge of a newly esta ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infraspecific Taxon
In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon or infraspecies. (A "taxon", plural "taxa", is a group of organisms to be given a particular name.) The scientific names of botanical taxa are regulated by the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN). This specifies a 'three part name' for infraspecific taxa, plus a 'connecting term' to indicate the rank of the name., Art. 24 An example of such a name is ''Astrophytum myriostigma'' subvar. ''glabrum'', the name of a subvariety of the species '' Astrophytum myriostigma'' (bishop's hat cactus). Names below the rank of species of cultivated kinds of plants and of animals are regulated by different codes of nomenclature and are formed somewhat differently. Construction of infraspecific names Article 24 of the ICN describes how infraspecific names are constructed. The order of the three parts of an infraspecific name is: :genus ...

Erica (plant)
''Erica'' is a genus of roughly 857 species of flowering plants in the family Ericaceae. The English common names heath and heather are shared by some closely related genera of similar appearance. The genus ''Calluna'' was formerly included in ''Erica'' – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. ''Erica'' is sometimes referred to as "winter (or spring) heather" to distinguish it from ''Calluna'' "summer (or autumn) heather". Etymology The Latin word ''erica'' means "heath" or "broom". It is believed that Pliny adapted ''erica'' from Ancient Greek ἐρείκη. The expected Anglo-Latin pronunciation, , may be given in dictionaries (''OED'': "Erica"), but is more commonly heard. Description Most of the species of ''Erica'' are small shrubs from high, though some are taller; the tallest are '' E. arborea'' (tree heath) and '' E. scoparia'' (besom heath), both of which can reach up ...
