Foxglove
''Digitalis'' ( or ) is a genus of about 20 species of herbaceous perennial plants, shrubs, and biennials, commonly called foxgloves. ''Digitalis'' is native to Europe, Western Asia, and northwestern Africa. The flowers are tubular in shape, produced on a tall spike, and vary in colour with species, from purple to pink, white, and yellow. The name derives from the Latin word for "finger". The genus was traditionally placed in the figwort family, Scrophulariaceae, but phylogenetic research led taxonomists to move it to the Veronicaceae in 2001. More recent phylogenetic work has placed it in the much enlarged family Plantaginaceae. The best-known species is the common foxglove, '' Digitalis purpurea''. This biennial is often grown as an ornamental plant due to its vivid flowers, which range in colour from various purple tints through pink and purely white. The flowers can also possess various marks and spottings. Other garden-worthy species include ''D. ferruginea'', ''D. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digitalis Purpurea
''Digitalis purpurea'', the foxglove or common foxglove, is a toxic species of flowering plant in the plantain family Plantaginaceae, native to and widespread throughout most of temperate Europe. It has also naturalized in parts of North America, as well as some other temperate regions. The plant is a popular garden subject, with many cultivars available. It is the original source of the heart medicine digoxin (also called digitalis or digitalin). This biennial plant grows as a rosette of leaves in the first year after sowing, before flowering and then dying in the second year (i.e., it is monocarpic). It generally produces enough seeds so that new plants will continue to grow in a garden setting. Description ''Digitalis purpurea'' is an herbaceous biennial or short-lived perennial plant. The leaves are spirally arranged, simple, long and broad, and are covered with gray-white pubescent and glandular hairs, imparting a woolly texture. The foliage forms a tight rosette ...

Digoxin
Digoxin (better known as digitalis), sold under the brand name Lanoxin among others, is a medication used to treat various heart disease, heart conditions. Most frequently it is used for atrial fibrillation, atrial flutter, and heart failure. Digoxin is one of the oldest medications used in the field of cardiology. It works by increasing myocardial contractility, increasing stroke volume and blood pressure, reducing heart rate, and somewhat extending the time frame of the Muscle contraction, contraction. Digoxin is taken by mouth or by intravenous, injection into a vein. Digoxin has a half life of approximately 36 hours given at average doses in patients with normal renal function. It is excreted mostly unchanged in the urine. Common side effects include gynecomastia, breast enlargement with other side effects generally due to an excessive dose. These side effects may include loss of appetite, nausea, trouble seeing, confusion, and an Heart arrhythmia, irregular heartbeat. Gre ...

Digitalis Atlantica
''Digitalis atlantica'' is a species of perennial flowering plant in the family Plantaginaceae. It is native to Algeria. Description ''Digitalis atlantica'' is a biennial or perennial herb. The plant leaves grow in the shape of a rosette until flowering stems develop in the second year. Leaves are downy, finely wrinkled on the upper surface and grey-green. The leaves are ovate, with toothed edges, and may measure up to 25cm long. The flowering stem can grow up to 2m tall, with flowers in a tall spike during the flowering period of spring to summer. Toxicity Like all species in the ''Digitalis'' genus, ''Digitalis atlantica'' is also toxic. However, this particular species seems to have the lowest cardenolide A cardenolide is a type of steroid. Many plants contain derivatives, collectively known as cardenolides, including many in the form of cardenolide glycosides (cardenolides that contain structural groups derived from sugars).

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Generic Epithet
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineage). # rea ...

Digitalis Cedretorum
''Digitalis cedretorum'' is a species of flowering plant in the family Plantaginaceae that is native to Morocco. Taxonomy It was first described as ''Digitalis lutea'' subsp. ''cedretorum'' in 1936 by the French botanist Louis Emberger. Another French botanist, René Maire, raised it to an independent species four years later, 1940. It was first collected in a cedar woodland on a granite-derived substrate, at 2,500 metres in altitude in the eastern Atlas Mountains The Atlas Mountains are a mountain range in the Maghreb in North Africa. They separate the Sahara Desert from the Mediterranean Sea and the Atlantic Ocean; the name "Atlantic" is derived from the mountain range, which stretches around through M ..., north of a town called Masker.

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] |
Digitalis Cariensis
''Digitalis cariensis'' is a type of foxglove and part of a flowering plant species in the family Plantaginaceae, native to southwestern to southern Turkey. In Muğla vilayet, it is locally known as ''yüksükotu'', which generally means 'foxglove' in the Turkish language. A more specific name for this species is ''ishalotu'', but the term may also be used for different plants. Taxonomy A certain Chr. Pinard travelled twice to the region of Caria in the Ottoman Empire, first in 1842 and again in 1843. He collected plant specimens and sent them to Swiss botanist Alphonse de Candolle, who duly passed them on to the greatest expert of the flora of the Near and Middle East at the time, Pierre Edmond Boissier, also a Swiss botanist. As such Pinard collected the first scientific samples of the species ''Digitalis cariensis'', as Boissier provisionally named it, in this region. Pinard sent a number of duplicates (especially in 1843), which could then be used to trade with other botani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
