× Amarygia
× ''Amarygia'' is an artificial hybrid genus of the genera ''Amaryllis'' and ''Brunsvigia''. Description The flowers usually show a closer resemblance to ''Amaryllis'' than to ''Brunsvigia''. History According to botanist Max Bourke the species was first crossbred by John Bidwell, that was undescribed. Bourke proposes the name for the species as "× Amarygia," and the subspecies "× Amarygia parkeri" with Amarygia standing for ameliae. Characteristics The species is unable to reproduce with Atropa bella-donna or closely related pollen strains. The flowers have a Pitcher plant, pitcher like appearance and tilt downward. Seeds in the species start out yellow and then progressively become red over time before hatching. Taxonomy It was published by Raffaele Ciferri and Valerio Giacomini in 1950. Species It has two species: *× Amarygia bidwillii, × ''Amarygia bidwillii'' (a hybrid of ''Amaryllis belladonna'' and ''Brunsvigia orientalis'') *× Amarygia parkeri, × ''Amarygia par ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amaryllis
''Amaryllis'' () is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, '' Amaryllis belladonna'', is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna. For many years there was confusion among botanists over the generic names ''Amaryllis'' and ''Hippeastrum'', one result of which is that the common name 'amaryllis' is mainly used for cultivars of the genus ''Hippeastrum'', widely sold in the winter months for their ability to bloom indoors. Plants of the genus ''Amaryllis'' are known as belladonna lily, Jersey lily, naked lady, amarillo, Easter lily in Southern Australia or, in South Africa, March lily due to its propensity to flower around March. This is one of numerous genera with the common name 'lily' due to their flower shape and growth habit. However, they are only distantly related ...

Brunsvigia
''Brunsvigia'' is a genus of African flowering plants in the family Amaryllidaceae, subfamily Amaryllidoideae. It contains about 20 species native to southeastern and southern Africa from Tanzania to the Cape Provinces of South Africa. Description Vegetative characteristics ''Brunsvigia'' are perennial, deciduous, temperate, bulbous herbal plants. Most species have subterranean bulbs but they are usually half-exposed in ''B. herrei'' and ''B. josephinae''. Bulbs are tender, usually large (up to 20 cm diameter), winter-growing and summer- dormant, generally flowering in early autumn. Tunics are often thick and cartilaginous, typically brittle and tan-coloured, although they are brown and papery in ''B. josephinae'' and ''B. litoralis''. The leaves are annual; when mature, the leaves are broad and oblong to tongue-shaped. In species with small bulbs – ''B. radula'', ''B. comptonii'', and ''B. namaquana'' – there are just two or three leaves per plant but most other ...

Botanist
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bidwell
John Bidwell (August 5, 1819 – April 4, 1900), known in Spanish as Don Juan Bidwell, was an American pioneer, politician, and soldier. Bidwell is known as the founder of the city of Chico, California. Born in New York, he emigrated at the age of 22 to Alta California (then a part of Mexico) as part of the Bartleson–Bidwell Party, one of the first expeditions of American emigrants along the California Trail. In California, he became a Mexican citizen and a prominent landowner, receiving multiple rancho grants from the governors of Alta California. Following the U.S. Conquest of California, Bidwell went on to serve in the California Senate and then in the U.S. House of Representatives. Early life Bidwell was born in 1819 in Chautauqua County, New York. His Bidwell ancestors immigrated to North America in the colonial era. His family moved to Erie, Pennsylvania, in 1829, and then to Ashtabula County, Ohio, in 1831. At age 17, he attended and shortly thereafter became princi ...

Atropa Bella-donna
''Atropa bella-donna'', commonly known as deadly nightshade or belladonna, is a toxic Perennial plant, perennial herbaceous plant in the nightshade family Solanaceae, which also includes tomatoes, potatoes and aubergine, eggplant. It is native to Europe and Western Asia, including Turkey, its distribution extending from England in the west to western Ukraine and the Iranian province of Gilan in the east. It is also naturalised or introduced in some parts of Canada, North Africa and the United States. The foliage and Berry (botany), berries are extremely toxin, toxic when ingested, containing tropane alkaloids. It can also be harmful to handle and/or touch these plants. These toxins include atropine, scopolamine, and hyoscyamine, which cause delirium and hallucinations, and are also used as pharmaceutical anticholinergics. Tropane alkaloids are of common occurrence not only in the Old World tribes Hyoscyameae (to which the genus Atropa belongs) and Mandragoreae, but also in the N ...

Pitcher Plant
Pitcher plants are carnivorous plants known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of pitcher plant are considered to be "true" pitcher plants and are formed by specialized leaves. The plants attract and drown the prey with nectar. Types The term "pitcher plant" generally refers to members of the Nepenthaceae and Sarraceniaceae families, but similar pitfall traps are employed by the monotypic Cephalotaceae and some members of the Bromeliaceae. The families Nepenthaceae and Sarraceniaceae are the most species-rich families of pitcher plants. Nepenthaceae The Nepenthaceae contains a single genus, '' Nepenthes'', containing over 100 species and numerous hybrids and cultivars. In this genus of Old World pitcher plants, the pitchers are borne at the end of tendrils that extend from the midrib of an otherwise unexceptional leaf. Old World pitcher plants are typically characterized as having reduced and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

× Amarygia Bidwillii
The multiplication sign (), also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. The symbol is also used in botany, in botanical hybrid names. The form is properly a four-fold rotationally symmetric saltire. The multiplication sign is similar to a lowercase X (). History The earliest known use of the symbol to indicate multiplication appears in an anonymous appendix to the 1618 edition of John Napier's . This appendix has been attributed to William Oughtred, who used the same symbol in his 1631 algebra text, , stating:Multiplication of species .e. unknownsconnects both proposed magnitudes with the symbol 'in' or : or ordinarily without the symbol if the magnitudes be denoted with one letter. Other works have been identified in which crossed diagonals appear in diagrams involving multiplied numbers, such as Robert Recorde's '' The Ground of Arts'' and Oswald Schrecke ...
