Arthrocnemum
''Arthrocnemum'' was a genus of shrubs in the family Amaranthaceae. Two or three species were included in the genus. They are halophytes with fleshy, apparently articulated plant stems and reduced leaves and flowers. Description Species formerly placed in ''Arthrocnemum'' are low shrubs up to , much branched from base, and often forming mats. Young stems are succulent, glaucous (sometimes yellowish), glabrous, and appear to be articulated. The opposite leaves are sessile, joined at base and forming a cup around the stem, fleshy, glabrous, their blades reduced to small, cuspidate scales up to 5 mm. The spike-like inflorescences stand terminal on lateral branches, they are not branched or with short lateral branches. Cymes of three flowers are sitting in the axils of fleshy, opposite bracts. The flowers are bisexual (sometimes the stamens of the lateral flowers mey be missing) and proterandric. The central flower is four-angled, the two lateral flowers are three-angled. ...

Amaranthaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus '' Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthroceras Subterminale
''Arthroceras subterminale'' is a species of flowering plant in the Amaranth family known by the common name Parish's glasswort. It is the only species in the genus ''Arthroceras''. This coastal and inland California native plant is a shrub that is found southerly into northern Mexico, also in both coastal and inland areas, including salt marshes, alkali flats, and other habitats with saline soils. As a halophyte, capable of growing in substrates with high salt concentrations, this glasswort is a perennial herb or subshrub growing in low clumps up to a meter wide mature plants having woody bases branching into fleshy, jointed green stems. The leaves appear as fused rings around stem, the tip of each individual blade narrowing to a point.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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. phylogenetic analysis should c ...

Southwest Asia
Western Asia, West Asia, or Southwest Asia, is the westernmost subregion of the larger geographical region of Asia, as defined by some academics, UN bodies and other institutions. It is almost entirely a part of the Middle East, and includes Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian Highlands, the Levant, the island of Cyprus, the Sinai Peninsula, and partly the Caucasus Region (Transcaucasia). The region is considered to be separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea.

Macaronesia
Macaronesia (Portuguese: ''Macaronésia,'' Spanish: ''Macaronesia'') is a collection of four volcanic archipelagos in the North Atlantic, off the coasts of Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which are formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface. Some of the Macaronesian islands belong to Portugal, some belong to Spain, and the rest belong to Cape Verde. Politically, the islands belonging to Portugal and Spain are part of the European Union. Geologically, Macaronesia is part of the African tectonic plate. Some of its islands – the Azores – are situated along the edge of that plate at the point where it abuts the Eurasian and North American plates. In one biogeographical system, the Cape Verde archipelago is in the Afrotropical realm while the other three archipelagos are in the Palearctic realm. According to the European Environment Agency, the three European archipelagos const ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Basin
In biogeography, the Mediterranean Basin (; also known as the Mediterranean Region or sometimes Mediterranea) is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation. Geography The Mediterranean Basin covers portions of three continents: Europe, Africa, and Asia. It is distinct from the drainage basin, which extends much further south and north due to major rivers ending in the Mediterranean Sea, such as the Nile and Rhône. Conversely, the Mediterranean Basin includes regions not in the drainage basin. It has a varied and contrasting topography. The Mediterranean Region offers an ever-changing landscape of high mountains, rocky shores, impenetrable scrub, semi-arid steppes, coastal wetlands, sandy beaches and a myriad islands of various shapes and sizes dotted amidst the clear blue sea.

Sal, Cape Verde
Sal (Portuguese for "salt") is an island in Cape Verde. Sal is a tourist destination with white sandy beaches and over 350 days of sunshine a year. It is one of the three sandy eastern islands of the Cape Verde archipelago in the central Atlantic Ocean, off the west coast of Africa. Cabo Verde is known for year-round kiteboarding, for the large reserve of Caretta turtles which hatch from July to September, and the music of Cesaria Evora. History For Europeans , the island was discovered on 3 December 1460 and named ''Llana'' ("flat"). This name was changed into the current "Sal" when the two large salt ponds ( Pedra de Lume and Santa Maria) were discovered. The first three centuries after its discovery, the island was only sparsely inhabited; in 1720 there was a small fishing village near present Palmeira. This changed when the salt industry was developed at the end of the 18th century, starting in Pedra de Lume. Santa Maria was founded in the south of the island in 1830 ...
