Delphinium Barbeyi
''Delphinium barbeyi'' is a species of flowering plant in the buttercup family known by the common names subalpine larkspur, tall larkspur, and Barbey's larkspur. It is native to the interior western United States, where it occurs in the states of Arizona, Colorado, New Mexico, Utah, and Wyoming. This species is a perennial herb growing up to 1.5 meters tall. The leaves line the stem but disappear from the lowest part of the stem by the time the plant blooms. The leaves are somewhat rounded in outline and are divided into several lobes. The tall inflorescence bears up to 50 flowers at a time, but a plant may produce hundreds of flowers. Each is borne on a pedicel up to 6 centimeters long. The flower has five dark purple-blue sepals with whitish or yellowish hairs inside. The fruit is a follicle up to 2.2 centimeters long. The plant is long-lived, capable of exceeding 75 years of age. It occupies wet habitat types in subalpine and alpine climates. It is a dominant member of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Huth
Ernst Huth (27 December 1845, Potsdam – 5 August 1897) was a German naturalist and botanist. He studied mathematics and natural sciences in Berlin, later working as a secondary school teacher in Frankfurt an der Oder. Beginning in 1883 he published the ''Monatliche Mittheilungen des Naturwissenschaftlichen Vereins Regierungsbezirkes Frankfurt'', in which he was the author of numerous scientific articles. He is known for his treatment of the botanical family Ranunculaceae, of which he was the taxonomic author of many species, especially plants within the genus ''Delphinium''. In 1908 August Brand named the genus ''Huthia'' (synonym ''Cantua'', family Polemoniaceae The Polemoniaceae (Jacob's-ladder or phlox family) are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversit ...) in his honor.

Delphinium Sapellonis
''Delphinium'' is a genus of about 300 species of annual and perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus. All members of the genus ''Delphinium'' are toxic to humans and livestock. The common name larkspur is shared between perennial ''Delphinium'' species and annual species of the genus ''Consolida''. Molecular data show that ''Consolida'', as well as another segregate genus, ''Aconitella'', are both embedded in ''Delphinium''. The genus name ''Delphinium'' derives from the Ancient Greek word () which means "dolphin", a name used in ''De Materia Medica'' for some kind of larkspur. Pedanius Dioscorides said the plant got its name because of its dolphin-shaped flowers. Habitat Species with short stems and few flowers such as ''Delphinium nuttallianum'' and ''Delphinium bicolor'' appear in habitats like prairies and the sagebrush steppe ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

Anthomyiidae
The Anthomyiidae are a large and diverse family of Muscoidea flies. Most look rather like small houseflies, but are commonly drab grey. The genus ''Anthomyia'', in contrast, is generally conspicuously patterned in black-and-white or black-and-silvery-grey. Most are difficult to identify, apart from a few groups such as the kelp flies that are conspicuous on beaches. The name Anthomyiidae was derived from Greek ''anthos'' (flower) plus ''myia'' (a fly). Some species are commonly called "root-maggots", as the larvae are found in the stems and roots of various plants. As larvae, some also feed on decaying plant material. The well-known grey "seaweed flies" or "kelp flies" (''Fucellia'') are examples. Others are scavengers in such places as birds' nests; yet other species are leaf miners; the family also includes inquilines, commensals, and parasitic larvae. Some species in the family are significant agricultural pests, particularly some from the genus '' Delia'', which includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyles Lineata
''Hyles lineata'', also known as the white-lined sphinx, is a moth of the family Sphingidae. They are sometimes known as the hummingbird moth because of their bird-like size (2-3 inch wingspan) and flight patterns. As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. With a wide geographic range throughout Central and North America, ''H. lineata'' is known to feed on many different host plants as caterpillars and pollinate a variety of flowers as adults. Larvae are powerful eaters and are known to form massive groupings capable of damaging crops and gardens. As adults, they use both visual and olfactory perception to locate plants from which they collect nectar. Description Caterpillar Larvae show wide variation in color. The larvae are black with orange spots arranged in lines down the whole body. Their head's prothoracic shield, and the anal plate, are one color, either green or orange with small black dots.David L. Wagner (20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollinator
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most families of aculeate wasps; ants; many families of flies; many lepidopterans (both butterflies and moths); and many families of beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination. A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process. Background Plants fall into pollination syndromes that reflect the type o ...

Stellula Calliope
The calliope hummingbird ( ; ''Selasphorus calliope'') is the smallest bird native to the United States and Canada. It has a western breeding range mainly from California to British Columbia, and migrates to the Southwestern United States, Mexico, and Central America for its wintering grounds. It was previously considered the only member of the genus ''Stellula'', but recent evidence suggests placement in the genus ''Selasphorus''. This bird was named after the Greek muse Calliope. The former genus name means "little star". Description The calliope is the smallest breeding bird found in Canada and the United States. The only smaller species ever found in the U.S. is the bumblebee hummingbird, an accidental vagrant from Mexico. An adult calliope hummingbird can measure in length, span across the wings and weigh .

Selasphorus Rufus
The rufous hummingbird (''Selasphorus rufus'') is a small hummingbird, about long with a long, straight and slender bill. These birds are known for their extraordinary flight skills, flying during their migratory transits. It is one of nine species in the genus ''Selasphorus''. Taxonomy The rufous hummingbird was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's '' Systema Naturae''. He placed it with all the other hummingbirds in the genus ''Trochilus'' and coined the binomial name ''Trochilus rufus''. Gmelin based his description on the ''Ruff-necked humming-bird'' that had been described by John Latham in 1782 and the ''Ruffed honeysucker'' that had been described by Thomas Pennant in 1785. The type locality is Nootka Sound on the west coast of Vancouver Island in western Canada. The rufous hummingbird is now placed with eight other species in the genus ''Selasphorus ''Selasphorus'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
