Tragopogon Miscellus
''Tragopogon miscellus'', the Moscow salsify, is a species native to the States of Washington and Idaho. Intensive studies over the course of many years have demonstrated that it originated as an allopolyploid hybrid between '' T. dubius'' and '' T. pratensis'', both of which are European species naturalized in the US. ''Tragopogon miscellus'' has become established in the wild, reproducing by its own, thus deserving recognition as a species.Ownbey, M. 1950.

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idaho
Idaho ( ) is a state in the Pacific Northwest region of the Western United States. To the north, it shares a small portion of the Canada–United States border with the province of British Columbia. It borders the states of Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. The state's capital and largest city is Boise. With an area of , Idaho is the 14th largest state by land area, but with a population of approximately 1.8 million, it ranks as the 13th least populous and the 7th least densely populated of the 50 U.S. states. For thousands of years, and prior to European colonization, Idaho has been inhabited by native peoples. In the early 19th century, Idaho was considered part of the Oregon Country, an area of dispute between the U.S. and the British Empire. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead ...

Allopolyploid
Polyploidy is a condition in which the cells of an organism have more than one pair of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two sets of chromosomes, where each set contains one or more chromosomes and comes from each of two parents, resulting in pairs of homologous chromosomes between sets. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis, the sporophyte generation is diploid and produces spores by meiosi ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tragopogon Dubius
''Tragopogon dubius'' (yellow salsify, western salsify, western goat's-beard, wild oysterplant, yellow goat's beard, goat's beard, goatsbeard, common salsify, salsify) is a species of salsify native to southern and central Europe and western Asia and found as far north and west as northern France. Although it has been reported from Kashmir and India, recent evidence suggests that specimens from these areas may be a different species. Western salsify has been introduced into North America where it has become widespread, being reported from all the continental United States except for a few in the far south-east, and all provinces of Canada except Newfoundland and the northern territories. Like most salsifies, the western salsify grows as an annual or occasionally biennial forb, reaching a height of typically 20–60 cm but sometimes almost a metre. It grows typically in warm, sheltered spots with moist soil. Its yellow flower head is 4–6 cm in diameter and is like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tragopogon Pratensis
''Tragopogon pratensis'' (common names Jack-go-to-bed-at-noon, meadow salsify, showy goat's-beard or meadow goat's-beard) is a biennial plant in the family Asteraceae, distributed across Europe and North America, commonly growing in fields (hence its name) and on roadsides. It is found in North America from southern Ontario to Massachusetts; most of England; on the eastern and southern edges of Scotland; and central Ireland but not the coastal edges. It flowers between June and October and its flowers have a diameter of 3–5 cm. The root and buds are edible, and it has a milky latex. Description The plant grows up to tall. It differs from viper's-grass ('' Scorzonera humilis'') in that viper's-grass has short, pale green bracts, whereas in goat's-beard they are long and pointed. The lower leaves are 10 to 30 cm long, lanceolate, keeled lengthwise, grey-green, pointed, hairless, with a white midrib. The upper leaves are shorter and more erect. It is the only Uni ...

Tomentose
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glabrousness (botany)
Glabrousness (from the Latin ''glaber'' meaning "bald", "hairless", "shaved", "smooth") is the technical term for a lack of hair, down, setae, trichomes or other such covering. A glabrous surface may be a natural characteristic of all or part of a plant or animal, or be due to loss because of a physical condition, such as alopecia universalis in humans, which causes hair to fall out or not regrow. In botany Glabrousness or otherwise, of leaves, stems, and fruit is a feature commonly mentioned in plant keys; in botany and mycology, a ''glabrous'' morphological feature is one that is smooth and may be glossy. It has no bristles or hair-like structures such as trichomes. In anything like the zoological sense, no plants or fungi have hair or wool, although some structures may resemble such materials. The term "glabrous" strictly applies only to features that lack trichomes at all times. When an organ bears trichomes at first, but loses them with age, the term used is ''glabrescen ...

Tragopogon
''Tragopogon'', also known as goatsbeard or salsify, is a genus of flowering plants in the family Asteraceae. It includes the vegetable known as salsify, as well as a number of common wild flowers. Salsifies are forbs growing as biennial or perennial plants. They have a strong taproot and milky sap. They generally have few branches, and those there are tend to be upright. Their leaves are somewhat grass-like. Flower colour varies within the genus, with some yellow species, and some bronze or purple. Seeds are achenes and are borne in a globe like that of a dandelion but larger, and are dispersed by the wind. The salsifies are mostly natives of Europe and Asia, but several species have been introduced into North America and Australia and have spread widely there. There is one species sometimes considered native to North America, ''Tragopogon mirus'', but it is in fact a hybrid of two non-native species. Some of the more common species of ''Tragopogon'' are known, in the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
