''Nasturtium africanum'', the Moroccan watercress, is an aquatic plant endemic to Morocco Morocco (),, ) officially the Kingdom of Morocco, is the westernmost country in the Maghreb region of North Africa.

Josias Braun-Blanquet
Josias Braun-Blanquet (3 August 1884 – 20 September 1980) was an influential phytosociologist and botanist. Braun-Blanquet was born in Chur, Switzerland and died in Montpellier, France. Biography Work In Josias Braun-Blanquet's dissertation, supervised by Charles Flahault, he worked on the phytosociology of the southern Cévennes. Subsequently he established the modern way of classifying vegetation according to floristic composition. This is what makes him one of the most influential botanists until today.Nicolson, M. (1993). National Styles, Divergent Classifications: A comparative case study from the history of French and American plant ecology. Knowledge and Society: Studies in the Sociology of Science Past and Present, 8, 139-186. Braun-Blanquet's way of classifying a plant community uses the scientific name of its most characteristic species as namesake, changing the ending of the generic name to "-etum" and treating the specific epithet as adjective. Thus, a particular t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morocco
Morocco (),, ) officially the Kingdom of Morocco, is the westernmost country in the Maghreb region of North Africa. It overlooks the Mediterranean Sea to the north and the Atlantic Ocean to the west, and has land borders with Algeria to the east, and the disputed territory of Western Sahara to the south. Mauritania lies to the south of Western Sahara. Morocco also claims the Spanish exclaves of Ceuta, Melilla and Peñón de Vélez de la Gomera, and several small Spanish-controlled islands off its coast. It spans an area of or , with a population of roughly 37 million. Its official and predominant religion is Islam, and the official languages are Arabic and Berber; the Moroccan dialect of Arabic and French are also widely spoken. Moroccan identity and culture is a mix of Arab, Berber, and European cultures. Its capital is Rabat, while its largest city is Casablanca. In a region inhabited since the Paleolithic Era over 300,000 years ago, the first Moroccan s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasturtium (genus)
''Nasturtium'' () is a genus of a small number of plant species in the family Brassicaceae (cabbage family) commonly known as watercress or yellowcress. The best known species are the edible ''Nasturtium officinale'' and '' Nasturtium microphyllum''. ''Nasturtium'' was previously synonymised with ''Rorippa'', but molecular evidence supports its maintenance as a distinct genus more closely related to ''Cardamine'' than to ''Rorippa'' ''sensu stricto''. These plants are related to garden cress and mustard, noteworthy for a peppery, tangy (pungent) flavor. The name ''Nasturtium'' comes from the Latin ''nasus tortus'', meaning "twisted nose", in reference to the effect on the nasal passages of eating the plants. ''Nasturtium'' foliage is used as food by the caterpillars of certain Lepidoptera, including ''Orthonama obstipata'' (The Gem). One species, '' Nasturtium gambellii'', is federally listed in California as an endangered species. Nomenclature The genus ''Nasturtium'' shoul ...

Freshwater Plants
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water i ...

Flora Of Morocco
Morocco provides a refuge for a rich and diverse flora with about 4,200 taxa, of which 22% (879 taxa) are endemic. The phytogeographic zones of Morocco comprise 8 zones: the Mediterranean zone (central 0–500m, middle 500-1,000m and upper 1,100-1500m), the Cedar zone (1000-2000m), the sub-Alpine zone (2,000-2,500m), the Alpine zone (2,500m+), the semi-desert scrub zone, the Reg , the sandy desert zone and the oases. Mediterranean or coastal zone Maquis and Garrique Mediterranean dry woodlands and steppe, Mediterranean woodlands and forests, lower Northern slopes of Rif and Tell Atlas. The climax of the Mediterranean coast is a well-developed maquis commonly associated with ''Clematis'', ''Smilax'', ''Lonicera'' and ''Asparagus''. Except in inaccessible or protected places the vegetation has been heavily grazed by domestic animals and this degraded maquis, called garrigue, is widespread. '' Poterium spinosum'', various ''Salvia'' and ''Cistus'' are the dominant plants of the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
