Asphodelaceae
Asphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is ''Asphodelus''. The family has a wide but scattered distribution throughout the tropics and temperate zones. Many of the species are cultivated as ornamentals. A few are grown commercially for cut flowers. Two species of '' Aloe'' are grown for their leaf sap, which has medicinal and cosmetic uses. ''Xanthorrhoea'' is endemic to Australia. Description Members of the Asphodelaceae are diverse, with few characters uniting the three subfamilies currently recognized. The presence of anthraquinones is one common character. The flowers (the inflorescence) are typically borne on a leafless stalk ( scape) which arises from a basal rosette of leaves. The individual flowers have jointed stalks ( ...

Hemerocallidoideae
Hemerocallidoideae is the a subfamily of flowering plants, part of the family Asphodelaceae ''sensu lato'' in the monocot order Asparagales according to the APG system of 2016. Earlier classification systems treated the group as a separate family, the Hemerocallidaceae. The name is derived from the generic name of the type genus, ''Hemerocallis''. The largest genera in the group are ''Dianella'' (with 20 species), ''Hemerocallis'' (15), and '' Caesia'' (11). In the 21st century, the group has had two basic forms, depending on whether '' Johnsonia'' and its relatives are included or not. Each of these forms can vary by the inclusion or exclusion of '' Xeronema''. If defined narrowly, most of the group are native to tropical and temperate Eurasia and Australia. They also occur in New Zealand, many Pacific islands, western South America, and Madagascar, but not in Sub-Saharan Africa or North America.Ole Seberg. 2007. "Hemerocallidaceae" pages 370-371.

Monotypic Asphodelaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Marettimo
Marettimo (; Sicilian: ''Marrètimu'') is one of the Aegadian Islands in the Mediterranean Sea west of Sicily, Italy. It forms a part of the municipality (''comune'') of Favignana in the Province of Trapani. It takes about an hour to reach the island from Trapani. History The ancient name of the island was Hiera, part of the Greek name ''Hierà Nèsos'' (Ἱερά Νήσος), which means "Sacred Island" in Greek. Indeed, its Latin name used by Pliny was also "Sacra". The name Marettimo probably comes from the words ''mar'' (sea) and ''timo'' (thyme) due to the profusion of thyme on the island. However, it may stem from a local pronunciation of the word "maritimo". The island was an important observation point during Roman times, hence the Casa Romana, where it was easy to observe passing maritime traffic. The sea routes between Italy and North Africa and Italy and Spain (via Sardinia) would pass Marettimo. Abu Abd Allah Muhammad al-Idrisi (1099–1165 or 1166), the Moroccan ...

Pyrenees
The Pyrenees (; es, Pirineos ; french: Pyrénées ; ca, Pirineu ; eu, Pirinioak ; oc, Pirenèus ; an, Pirineus) is a mountain range straddling the border of France and Spain. It extends nearly from its union with the Cantabrian Mountains to Cap de Creus on the Mediterranean Sea, Mediterranean coast. It reaches a maximum altitude of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between. Historically, the Crown of Aragon and the Kingdom of Navarre extended on both sides of the mountain range. Etymology In Greek mythology, Pyrene (mythology), Pyrene is a princess who eponym, gave her name to the Pyrenees. The Greek historiography, Greek historian Herodotus says Pyrene is the name of a town in Celts, Celtic Europe. According to Silius Italicus, she was the virgin daughter of Bebryx, a king in Narbonensis, Mediterranean Gaul by whom the hero Hercules was given hospitality during his ...

Relict (biology)
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or group did n ...

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] |
Derrynane
Derrynane, officially Darrynane (), is a small village in the civil parish of Kilcrohane in County Kerry, Ireland. It is located on the Iveragh peninsula, just off the N70 national primary road near Caherdaniel on the shores of Derrynane Bay. History A dolmen (or Stone Age passage grave) in the area may date from 3000 BC. Around Derrynane, sites dating from 2000 BC, are associated with the Beaker people who were mining for copper in the area. Saint Fionan founded a monastery in the area in the 6th century. In the 18th century, Derrynane harbour became a thriving centre for trade with France and Spain. Places of interest Derrynane is the site of Derrynane Abbey and Derrynane House. The latter was the home of Daniel O'Connell and is now a National Monument and part of a 320-acre (1.3 km²) national historic park. Staigue Fort, one of Ireland's finest examples of an ancient ringfort, is located approximately 7 kilometers east from Derrynane. Another stone ringfort, Loh ...

British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...

Capsule (fruit)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classif ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...
