Asphodeline Tenuior
''Asphodeline tenuior'', the thin asphodeline, is a species of plant in the family Asphodelaceae, subfamily Asphodeloideae.Stevens, P.F. (2001 onwards)"Asphodeloideae" ''Angiosperm Phylogeny Website''. Retrieved 2016-06-10. It is native to the Caucasus (southern Russia, Georgia, Armenia, Azerbaijan), as well as from eastern Turkey and northwestern Iran. Within Russia, it is known from eastern Krasnodar Krai, Karachay-Cherkessia, Stavropol Krai and western Kabardino-Balkaria. It can be found on stony slopes and scree on limestone and sandstone, from elevations of 500–1,000 m. It is threatened by habitat loss and degradation, due to lime pits, slope terracing and cattle pasturing. ;Subspecies and varieties # ''Asphodeline tenuior'' var.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Natural Product
A natural product is a natural compound or substance produced by a living organism—that is, found in nature. In the broadest sense, natural products include any substance produced by life. Natural products can also be prepared by chemical synthesis (both semisynthesis and total synthesis) and have played a central role in the development of the field of organic chemistry by providing challenging synthetic targets. The term natural product has also been extended for commercial purposes to refer to cosmetics, dietary supplements, and foods produced from natural sources without added artificial ingredients. Within the field of organic chemistry, the definition of natural products is usually restricted to organic compounds isolated from natural sources that are produced by the pathways of primary or secondary metabolism. Within the field of medicinal chemistry, the definition is often further restricted to secondary metabolites. Secondary metabolites (or specialized metabolites ...

Tenual
Tenual is a natural product derived from ''Asphodeline tenuior''. It is a 3-benzoxepin derivative with methoxy, methyl, hydroxymethyl The hydroxymethyl group is the name for a substituent with the structural formula −CH2−OH. It consists of a methylene bridge (−CH2− unit) bonded to a hydroxyl group (−OH). This makes the hydroxymethyl group an alcohol. It has the identic ..., and carbaldehyde side chains.

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...

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 ( ...
