Welw.
Friedrich Martin Josef Welwitsch (25 February 1806 – 20 October 1872) was an Austrian explorer and botanist who in Angola was the first European to describe the plant ''Welwitschia mirabilis''. His report received wide attention among the botanists and general public, comparable only to the discovery of two other plants in the 19th century, namely ''Victoria amazonica'' and ''Rafflesia arnoldii''.Strlič, Matija. "Dr. Friderik Velbič, 1806–1872". ''Proteus, the journal of the Natural Sciences Society of Slovenia''. Year 61, No. 9/10 (pp. 396-404). ISSN 0033-1805. In Angola, Welwitsch also discovered ''Rhipsalis baccifera'', the only cactus species naturally occurring outside the New World. It was found a few years later in Sri Lanka too, which reignited the now already one-and-a-half-century-old debate on the origin of cacti in Africa and Asia. At the time, the debate concluded with the conviction of numerous authors that they were introduced and spread by migratory birds. ...

Cyphostemma Macropus
''Cyphostemma'' is a flowering plant genus in the family Vitaceae, with around 250 species distributed throughout the tropics and subtropics. These species are caudiciform and used to belong to the genus ''Cissus''. The genus name comes from Greek ''kyphos'', meaning ''hump'', and ''stemma'', meaning ''garland''. Within the Vitaceae, ''Cyphostemma'' is most closely related to ''Cayratia'' and ''Tetrastigma''. All species of ''Cyphostemma'' were once included in the genus ''Cissus'' but are now considered to be distinct. Distribution They originate from Northeast Africa to southern Arabia, in particular from Madagascar through to Indochina.

Welwitschia
''Welwitschia'' is a monotypic gymnosperm genus, comprising solely the distinctive ''Welwitschia mirabilis'', endemic to the Namib desert within Namibia and Angola. ''Welwitschia'' is the only living genus of the family Welwitschiaceae and order Welwitschiales in the division Gnetophyta, and is one of three living genera in Gnetophyta, alongside ''Gnetum'' and ''Ephedra''. Informal sources commonly refer to the plant as a "living fossil". Naming ''Welwitschia'' is named after the Austrian botanist and doctor Friedrich Welwitsch, who described the plant in Angola in 1859. Welwitsch was so overwhelmed by the plant that he, "could do nothing but kneel down ..and gaze at it, half in fear lest a touch should prove it a figment of the imagination." Joseph Dalton Hooker of the Linnean Society of London, using Welwitsch's description and collected material along with material from the artist Thomas Baines who had independently recorded the plant in Namibia, described the species.

Acanthosicyos Horridus
''Acanthosicyos horridus'' is an unusual melon that is endemic to the Namib desert. In English it is known as Nara, butter-nuts, or butterpips; in one of the Khoisan languages it is locally called or ("!" is pronounced with a click, somewhat like the "tsk" when English people are tutting, tsk-tsk). Description It is a dioecious, leafless, phreatophyte (meaning its roots penetrate deep down to water near the water table) that is found in sandy deserts but not stony plains, in areas with access to ground water such as ephemeral rivers and paleochannels, where sand accumulating in the shelter of its stems can form hummocks up to 1000–1500 m2 in area and 4 meters in height. Its stems may rise more than a meter above the hummocks, while its system of thick taproots can extend up to 50 m downward. The plant is leafless, so modified stems and spines 2–3 centimetres long serve as the photosynthetic "organs" of the plant. The plant can survive many years without water. Ecology I ...

Pachypodium Namaquanum
''Pachypodium namaquanum'', also known as halfmens or elephants trunk, is a succulent plant of Southern Africa. The genus name ''Pachypodium'' is from the Greek for 'thick foot', an allusion to its swollen base, while the species name ''namaquanum'' is a reference to Namaqualand. Distribution The succulent plant is native to the arid, rocky mountains of the Richtersveld in the Northern Cape of South Africa and in southern Namibia. It is found in its greatest numbers in the Gariep Centre which has the greatest variety of succulents on earth. Rainfall here occurs mainly in winter and varies from 50 to 150 mm. Extremely arid conditions are to be found in the rain shadows of certain mountain ranges where the rainfall may be 15 mm or less. Thick fog moving inland from the Atlantic coast can add to the precipitation. Temperatures in summer may reach 50 °C.

Pachypodium Lealii
''Pachypodium lealii'', the bottle tree, is a species of plant included in the ''genus'' ''Pachypodium''. The scientific name derives from the 19th century Portuguese geologist Fernando da Costa Leal, who described the bottle tree during an exploration in southern Angola. This species can be either a shrub or a tree up to 6 meters tall and is characterized by the thick bottle-shaped trunk, which is almost branchless until the top. The branches are few and covered by slender thorns up to 30 cm long. Leaves are oblong and are covered with short hairs on both surfaces. The flowers, shown below in detail, are present in the spring, when the tree is leafless. The white flowers, characteristic of the family Apocynaceae, cluster around the tips of the branches. The plant produces a watery latex, rich in toxic alkaloids, used by local populations as arrow poison for hunting. In contact with the eyes this latex can produce blindness.

Geastrales
Geastrales is an order of gasterocarpic basidiomycetes (fungi) that are related to Cantharellales. The order contains the single family Geastraceae, commonly known as "earthstars", which older classifications had placed in Lycoperdales, or Phallales. Approximately 64 species are classified in this family, divided among eight genera, including the ''Geastrum'', ''Myriostoma'' and '' Sphaerobolus''. The ''Sphaerobolus'' are known as "shotgun fungus" or "cannonball fungus". They colonize wood-based mulches and may throw black, sticky, spore-containing globs onto nearby surfaces. The fruiting bodies of several earthstars are hygroscopic: in dry weather the "petals" will dry and curl up around the soft spore sac, protecting it. In this state, often the whole fungus becomes detached from the ground and may roll around like a tumbleweed. Once mature, their exoperidium splits into a variable number of rays, which give Geastrum their visible star shape. The exoperidial rays are ther ...

Salzburg
Salzburg (, ; literally "Salt-Castle"; bar, Soizbuag, label=Bavarian language, Austro-Bavarian) is the List of cities and towns in Austria, fourth-largest city in Austria. In 2020, it had a population of 156,872. The town is on the site of the Roman settlement of ''Iuvavum''. Salzburg was founded as an episcopal see in 696 and became a Prince-Archbishopric of Salzburg, seat of the archbishop in 798. Its main sources of income were salt extraction, trade, and gold mining. The fortress of Hohensalzburg Fortress, Hohensalzburg, one of the largest medieval fortresses in Europe, dates from the 11th century. In the 17th century, Salzburg became a center of the Counter-Reformation, with monasteries and numerous Baroque churches built. Historic Centre of the City of Salzburg, Salzburg's historic center (German language, German: ''Altstadt'') is renowned for its Baroque architecture and is one of the best-preserved city centers north of the Alps.

Geastrum Welwitschii
''Geastrum welwitschii'' is a species of fungus in the earthstar family. When young and unopened, the fruit bodies resemble small spheres lying in the soil. As the mushroom matures, the thick leathery outer layer of tissue (the peridium) splits star-like to form a number of fleshy arms, which curve downward to reveal the inner spore sac that contains the fertile tissue known as the gleba. The spore sac has a narrow grooved opening at the top where the spores are released. Fully expanded, the fruit bodies are up to wide and tall. First collected from Spain in the mid-19th century, the fungus is distributed in Europe, North America, and Bermuda. Taxonomy 150px, left, Friedrich Welwitsch The fungus was first collected in Spain by the Austrian explorer and botanist Friedrich Welwitsch. British mycologist Miles Joseph Berkeley obtained the specimens and thought them to be ''Geastrum fimbriatum''. He sent a specimen to the French mycologist Camille Montagne in 1856, who named it ...

Duchy Of Carinthia
The Duchy of Carinthia (german: Herzogtum Kärnten; sl, Vojvodina Koroška) was a duchy located in southern Austria and parts of northern Slovenia. It was separated from the Duchy of Bavaria in 976, and was the first newly created Imperial State after the original German stem duchies. Carinthia remained a State of the Holy Roman Empire until its dissolution in 1806, though from 1335 it was ruled within the Austrian dominions of the Habsburg dynasty. A constituent part of the Habsburg monarchy and of the Austrian Empire, it remained a Cisleithanian crown land of Austria-Hungary until 1918. By the Carinthian Plebiscite in October 1920, the main area of the duchy formed the Austrian state of Carinthia. History In the seventh century the area was part of the Slavic principality of Carantania, which fell under the suzerainty of Duke Odilo of Bavaria in about 743. The Bavarian stem duchy was incorporated into the Carolingian Empire when Charlemagne deposed Odilo's son Duke Ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
