Haworthia Emelyae
''Haworthia emelyae'' (synonym with ''Haworthia picta'') is a species of the genus ''Haworthia'' in the family Asphodelaceae, endemic to the Western Cape Province in South Africa. Description This species is one of the ''"retuse"'' species of ''Haworthia'', meaning that it usually grows sunken beneath the ground with its flattened leaves only showing on the surface. Its rosette of succulent leaves are turned back ("retuse") so as to provide a flat and level face, on the surface of the ground. In this form, it is similar to other retuse haworthias (e.g. ''Haworthia retusa'', '' Haworthia bayeri'', '' Haworthia springbokvlakensis'', '' Haworthia pygmaea'', ''Haworthia mirabilis'' and ''Haworthia magnifica''). A distinctive feature is the convex shape of the leaf faces. The faces appear to bulge upwards, with the leaf tips bent back downwards. Another distinctive feature is the flecked, speckled (often pink) vein markings on the leaf faces. These markings have made this species a ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia
''Haworthia'' is a large genus of small succulent plants endemic to Southern Africa (Mozambique, Namibia, Lesotho, Eswatini and South Africa). Like the aloes, they are members of the subfamily Asphodeloideae and they generally resemble miniature aloes, except in their flowers, which are distinctive in appearance. They are popular garden and container plants. Description and characteristics ''Haworthias'' are small succulent plants, forming rosettes of leaves from to exceptionally in diameter, depending on the species. These rosettes are usually stemless but in some species stems reach up to . The inflorescences of some species may exceed in height. The plants can grow solitary or can be clump-forming. Many species have firm, tough, fleshy leaves, usually dark green in colour, whereas others are softer and contain leaf windows with translucent panels through which sunlight can reach internal photosynthetic tissues. Their flowers are small, and generally white. Though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ( ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. Ano ...

Haworthia Retusa
''Haworthia retusa'' is a species of flowering plants of the genus ''Haworthia'' in the family Asphodelaceae, endemic to a very small area around Riversdale, in the Western Cape Province in South Africa. Growing to tall and broad, it is a perennial succulent with thick triangular leaves and small white tubular flowers held in tall racemes. Etymology The genus name ''Haworthia'' honors the British botanist Adrian Hardy Haworth (1767–1833), while the species epitheton ''retusa'' derives from Latin and refers to the "retused" leaf-shape. Description A distinctive feature is the " retuse", deltoid, recurved shape of the leaves. The upturned, recurved face of each leaf forms a triangle, which is transparent (and often lined). The species can be easily recognised by its leaf-top windows, which are distinctively shiny. Plants grow as tight rosettes of thick, firm, fleshy, highly recurved/truncated leaves. It is usually a solitary rosette in the wild. In cultivation it can off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haworthia Springbokvlakensis
''Haworthia springbokvlakensis'' is a species of the genus ''Haworthia'' in the family Asphodelaceae, endemic to a very restricted area of the Eastern Cape Province in South Africa. Description This is a "retuse" species of ''Haworthia'' and is easily confused with its relatives (e.g. '' Haworthia pygmaea'', ''Haworthia retusa'', ''Haworthia bayeri'', ''Haworthia mirabilis'', ''Haworthia emelyae'' and ''Haworthia magnifica''). It can be distinguished from its relatives though, by its very rounded leaf tips and its extremely swollen, turgid leaf faces. Rosettes are usually solitary, as the plant rarely forms offsets. It is very slow-growing. Distribution The natural range of this species is an arid area around the "Springbokvlakte" farm, in the Eastern Cape Province, South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haworthia Pygmaea
''Haworthia pygmaea'' is a species of the genus ''Haworthia'' in the family Asphodelaceae, endemic to the Mossel Bay area of the Western Cape, South Africa. Description This species can be distinguished from its relatives, by its flat leaf ends (not convex like ''Haworthia emelyae'') which have more rounded tips, and a grey colour. Some individuals have leaves with a surface that is scabrous (rough) or papillate (bearing minute, nipple-shaped protuberances). These papillate forms have become especially popular in cultivation.
