Hymenonema Graecum
''Hymenonema graecum'' is a perennial herbaceous plant of 20–70 cm, that rests with its buds at or just under the surface of the soil (a so-called hemicryptophyte). The Greek vernacular name is Αδραλίδα (Adralida), meaning "handsome Lida". The leaves are pinnate, and may be up to 1 cm wide. The ligulate flowers are yellow. The species is an endemic of Greece. Description ''Hymenonema graecum'' is a perennial herb with glandular, rough but softly hairy shoots. It has twenty chromosomes (2n = 20). The rosette consists of pinnately lobed leaves, the end-lobe largest, oval, with a rounded tip, and segments often with teeth. Few small leaves on the stem are slightly pinnate and linear further up. The plant is of average height (20–70 cm). It usually has 1-3 yellow inflorescences (heads) per stem, each on a peduncle of 10–30 cm. The narrow yellow ligulate florets with five short teeth at the tip sometimes have a whitish base, the tube being hairy. T ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Cichorieae
The Cichorieae (also called Lactuceae) are a tribe in the plant family Asteraceae that includes 93 genera, more than 1,600 sexually reproductive species and more than 7,000 apomictic species. They are found primarily in temperate regions of the Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of floret. The genera ''Gundelia'' and ''Warionia'' only have disk florets, while all other genera only have ligulate florets. The genera that contain most species are ''Taraxacum'' (Crepidinae subtribe) with about 1,600 apomictic species, ''Hieracium'' with about 770 sexually reproducing and 5,200 apomictic species, and ''Pilosella'' with 110 sexually reproducing and 700 apomictic species (both Hieraciinae). Well-known members include lettuce, chicory, dandelion, and salsify. Description Most species are herbaceous, perennial, short-lived or annual plants, rarely subshrubs, shrubs or vines. All Cichorieae-species have latex canals in both t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Greece
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salinity
Salinity () is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ...

Crete
Crete ( el, Κρήτη, translit=, Modern: , Ancient: ) is the largest and most populous of the Greek islands, the 88th largest island in the world and the fifth largest island in the Mediterranean Sea, after Sicily, Sardinia, Cyprus, and Corsica. Crete rests about south of the Greek mainland, and about southwest of Anatolia. Crete has an area of and a coastline of 1,046 km (650 mi). It bounds the southern border of the Aegean Sea, with the Sea of Crete (or North Cretan Sea) to the north and the Libyan Sea (or South Cretan Sea) to the south. Crete and a number of islands and islets that surround it constitute the Region of Crete ( el, Περιφέρεια Κρήτης, links=no), which is the southernmost of the 13 top-level administrative units of Greece, and the fifth most populous of Greece's regions. Its capital and largest city is Heraklion, on the north shore of the island. , the region had a population of 636,504. The Dodecanese are located ...

Cyclades
The Cyclades (; el, Κυκλάδες, ) are an island group in the Aegean Sea, southeast of mainland Greece and a former administrative prefecture of Greece. They are one of the island groups which constitute the Aegean archipelago. The name refers to the islands ''around'' ("cyclic", κυκλάς) the sacred island of Delos. The largest island of the Cyclades is Naxos, however the most populated is Syros. History The significant Late Neolithic and Early Bronze Age Cycladic culture is best known for its schematic, flat sculptures carved out of the islands' pure white marble centuries before the great Middle Bronze Age Minoan civilization arose in Crete to the south. (These figures have been looted from burials to satisfy a thriving Cycladic antiquities market since the early 20th century.) A distinctive Neolithic culture amalgamating Anatolian and mainland Greek elements arose in the western Aegean before 4000 BCE, based on emmer and wild-type barley, sheep and goa ...

Validly Published Name
In botanical nomenclature, a validly published name is a name that meets the requirements in the ''International Code of Nomenclature for algae, fungi, and plants'' for valid publication. Valid publication of a name represents the minimum requirements for a botanical name to exist: terms that appear to be names but have not been validly published are referred to in the ''ICN'' as "designations". A validly published name may not satisfy all the requirements to be '' legitimate''. It is also not necessarily the correct name for a particular taxon and rank. Nevertheless, invalid names (''nomen invalidum'', ''nom. inval.'') are sometimes in use. This may occur when a taxonomist finds and recognises a taxon and thinks of a name, but delays publishing it in an adequate manner. A common reason for this is that a taxonomist intends to write a ''magnum opus'' that provides an overview of the group, rather than a series of small papers. Another reason is that the code of nomenclature chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Von Heldreich
Theodor Heinrich Hermann von Heldreich (3 March 1822 – 7 September 1902) was a German botanist born in Dresden. In 1851, he settled in Greece for the rest of his life. He carried out botanical experiments in the country. He published thirteen volumes of the “Herbarium Graecum Normale” between 1856 and 1896. In Greece, he served as director of the National Garden of Athens for over 50 years. He was also director of the natural history museum of Athens. Heldreich was good friends with Charles Darwin. Biography Scion of an old aristocratic family, he was the son of Conrad Friedrich Robert Heldreich and Amalia Charlotte Humbold. He initially studied philosophy. A love of botany, however, took him to Montpellier in 1837 to study under Professor Michel Félix Dunal. He later completed his botanical education in Geneva (1838–1842). In 1841, he was honoured by botanist Pierre Edmond Boissier, who named a genus of plants (in family Brassicaceae) from Palestine and Turkey ...

Pierre Edmond Boissier
Pierre Edmond Boissier (25 May 1810 Geneva – 25 September 1885 Valeyres-sous-Rances) was a Swiss prominent botanist, explorer and mathematician. He was the son of Jacques Boissier (1784-1857) and Caroline Butini (1786-1836), daughter of Pierre Butini (1759-1838) a well-known physician and naturalist from Geneva. With his sister, Valérie Boissier (1813-1894), he received a strict education with lessons delivered in Italian and Latin. Edmond's interest in natural history stemmed from holidays in the company of his mother and his grandfather, Pierre Butini at Valeyres-sous-Rances. His hikes in the Jura and the Alps laid the foundation of his zest for later exploration and adventure. He attended a course at the Academy of Geneva given by Augustin Pyramus de Candolle. Edmond Boissier collected extensively in Europe, North Africa and western Asia, on occasion accompanied by his daughter, Caroline Barbey-Boissier (1847-1918) and her husband, William Barbey (1842-1914), who coll ...
