Echinopsis Spachiana
''Soehrensia spachiana'', commonly known as the golden torch, (white) torch cactus or golden column, is a species of cactus native to South America. Previously known as ''Trichocereus spachianus'' for many years, it is commonly cultivated as a pot or rockery plant worldwide. It has a columnar habit, with a lime-green cylindrical body with 1–2 cm long golden spines. Description ''Soehrensia spachiana'' grows as a cactus with a columnar habit, reaching 2 m (7 ft) high, with a diameter of . Vertical branches arise from the base of the plant. Each column has 10–15 rounded ribs. The large areoles are around 1 cm apart, and have wavy yellow hairs. The straight spines are red-yellow initially, fading to white as they age. The central spine is around long, and is surrounded by 8 to 10 smaller radial spines that are in length. The white flowers are 15 cm (6 in) across and long, part of which is an 8 cm long tube. In their native habitat, the flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Antoine Lemaire
Charles Antoine Lemaire (1 November 1800, in Paris – 22 June 1871, in Paris), was a French botanist and botanical author, noted for his publications on Cactaceae. Education Born the son of Antoine Charles Lemaire and Marie Jeanne Davio, he had an excellent early education, and acquired the reputation of being an outstanding scholar. He studied at the University of Paris and was appointed as Professor of Classical Literature there. At some stage his botanical interest was sparked and developed by his association with M. Neumann, horticulturist at the Muséum national d'histoire naturelle, Museum of Natural History. Career He worked for some time as an assistant to M. Mathieu, at a nursery in Paris, building up a collection of Cactaceae, a group to which he would devote almost all of his life. In 1835, M. Cousin, a Parisian publisher, started a gardening journal and requested that he be its editor. For a number of years, he remained editor of ''Jardin Fleuriste'' and ''L'Horticu ...

Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Habit (biology)
Habit, equivalent to habitus in some applications in biology, refers variously to aspects of behaviour or structure, as follows: *In zoology (particularly in ethology), habit usually refers to aspects of more or less predictable ''behaviour'', instinctive or otherwise, though it also has broader application. Habitus refers to the characteristic form or morphology of a species. *In botany, habit is the characteristic form in which a given species of plant grows (see plant habit).Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Behavior In zoology, ''habit'' (not to be confused with ''habitus'' as described below) usually refers to a specific behavior pattern, either adopted, learned, pathological, innate, or directly related to physiology. For example: * ...the atwas in the ''habit'' of springing upon the oor knockerin order to gain admission... * If these sensitive parrots are kep ...

Areole
In botany, areoles are small light- to dark-colored bumps on cacti out of which grow clusters of spines. Areoles are important diagnostic features of cacti, and identify them as a family distinct from other succulent plants. Gordon Rowley - What is an Areole The spines are not easily detachable, but on certain cacti, members of the subfamily Opuntioideae, smaller, detachable bristles, glochids, also grow out of the areoles and afford additional protection. Areoles represent highly specialized branches on cacti. Apparently, they evolved as abortive branch buds while their spines evolved as vestigial leaves. In branched cacti, such as Opuntioidiae and the saguaro, new branches grow from areoles, because that is where the buds are. The development of the areole seems to have been an important element in the adaptation of cacti to niches in desert ecology. Some of the Opuntioideae have spines, as well as glochids, on their areoles; some have only glochids. Structurally, the gloc ...

Édouard Spach
Édouard Spach (23 November 1801 – 18 May 1879) was a French botanist. The son of a merchant in Strasbourg, in 1824 he went to Paris, where he studied botany with René Desfontaines (1750–1831) and Antoine-Laurent de Jussieu (1748–1836). He then became the secretary of Charles-François Brisseau de Mirbel (1776–1854). When de Mirbel became a professor at the Muséum national d'histoire naturelle (National Museum of Natural History), he followed him and remained at the museum for the remainder of his career. He published many monographs, including ''Histoire naturelle des végétaux. Phanérogames'' ("Natural history of plants: Spermatophytes"; fourteen volumes and an atlas, Roret, Paris, 1834–1848), and with Hippolyte François Jaubert (1798–1874), ''Illustrationes plantarum orientalium'' ("Illustrations of plants of the East"; five volumes, Roret, Paris, 1842–1857). The genus ''Spachea'' was named after him by Adrien-Henri de Jussieu [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alwin Berger
Alwin Berger (28 August 1871 – 20 April 1931) was a German botanist best known for his contribution to the nomenclature of succulent plants, particularly agaves and cacti. Born in Germany he worked at the botanical gardens in Dresden and Frankfurt. From 1897 to 1914 he was curator of the Giardini Botanici Hanbury, the botanical gardens of Sir Thomas Hanbury at La Mortola, near Ventimiglia in northwestern Italy, close to the border with France. After working in Germany from 1914 to 1919, Berger studied in the United States for three years, before spending his final years as director of the department of botany of the natural history museum in Stuttgart His main work, ''Die Agaven'', published in 1915, described 274 species of agave, divided into 3 subgenera, '' Littaea'', '' Euagave'' and ''Manfreda''. He also recognised a new genus of cactus, ''Roseocactus'', in 1925. The genera ''Bergerocactus'' (''Cactaceae'') and ''Bergeranthus'' (''Mesembryanthemaceae'') are named in ...

One small species, ''E. chamaecereus'', is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from ''echinos'' hedgehog or sea urchin, and ''opsis'' appearance, a reference to these plants' dense coverings of spines. They are remarkable for the great size, length of tube, and beauty of their flowers, which, borne upon generally small and dumpy stems, appear much larger and more attractive than would be expected.

Chloroplast
A chloroplast () is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in the cells. The ATP and NADPH is then used to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like ''Arabidopsis'' and wheat. A chloroplast is characterized by its two membranes and a high concentration of chlorophyll. Other plastid types, such as the leucoplast and the chromoplast, contain little chlorophyll and do not carry out photosynthesis. Chloroplasts are highly dynamic—they circulat ...

Soehrensia
''Soehrensia'' is a genus of cacti native to South America. It is native to northern Argentina, Bolivia, northern Chile, Paraguay and Peru, and has been introduced elsewhere, including Mexico, southern Africa and Spain. Taxonomy The genus was established by Curt Backeberg in 1938. The genus name of ''Soehrensia'' is in honour of Johannes Soehrens (died 1934), who was a Dutch botanist and Professor and Director of the Botanical Garden in Santiago de Chile. He was an authority on cacti. Studies in the 1970s and 1980s resulted in several formerly separate genera being absorbed into ''Echinopsis'', including ''Soehrensia'' and ''Helianthocereus'', until it was re-assessed to be a separate genus.Hunt, D.R. 2016: CITES Cactaceae Checklist. 3rd edition.
