Oreocarya
''Oreocarya'' (Perennial Cat's-Eye) is a genus of flowering plants in the family Boraginaceae. There are about 63 species and its native range extends from western and central Canada, through western United States to north Mexico. It is part of subtribe of ''Amsinckiinae''. It was once thought to be a either a subgenus or synonym of ''Cryptantha'' , as they both had plenty of tiny flowers, hairy leaves, and persisting dried flower stems. Botanist William Alfred Weber later noted that the 2 genera were different in form as ''Oreocarya'' was a "biennial or perennial from rosettes of basal leaves; flowers more than 5 mm in diameter, often distinctly long-tubular with prominent yellow eye", while ''Cryptantha'' was an "annual without rosettes of basal leaves; flowers minute, less than 5 mm diameter, short-tubed with inconspicuous eye". Description They are perennial or biennial, plants. Most species are perennials but a few (such as ''O. setosissima'' and ''O. virgata'') are bienni ...

Cryptantha
''Cryptantha'' is a genus of flowering plants in the borage family, Boraginaceae. They are known commonly as cat's eyes and popcorn flowers (the latter name is also used to refer to the closely related genus ''Plagiobothrys'',Hasenstab-Lehman, K. E. and M. G. Simpson. (2012)Cat's eyes and popcorn flowers: phylogenetic systematics of the genus ''Cryptantha'' s. l. (Boraginaceae).''Systematic Botany'' 37(3), 738-57. and members of the subtribe of ''Amsinckiinae''). They are distributed throughout western North America and western South America, but they are absent from the regions in between. These are annual or perennial herbs usually coated in rough hairs and bearing rounded flower corollas that are almost always white, but are yellow in a few species. Several morphological characters are used to distinguish species from one another, but the most definitive is the form of the nutlet, which varies in shape, size, color, and pattern of attachment.

Johnstonella
''Johnstonella'' is a genus of flowering plants belonging to the family Boraginaceae. Its native range is south western and southern USA to Mexico, Peru to southern South America. It is found in the American states of Arizona, California, Nevada, New Mexico, Texas and Utah, as well as in the countries of Argentina, Chile, Mexico and Peru. Taxonomy The genus name of ''Johnstonella'' is in honour of Ivan Murray Johnston (1898–1960), an American botanist. It was first described and published by August Brand in Repert. Spec. Nov. Regni Veg. Vol.21 on page 249 in 1925. Then in 1927, Ivan M. Johnston wrote that the genus of ''Oreocarya'' (in the Boraginaceae family) could be combined with ''Cryptantha''. Then Edwin Blake Payson in 1927 (A Monograph of the section ''Oreocarya'' of ''Cryptantha'', Ann. Mo. Bot. Gard. 14:211-358) agreed with Johnston and Payson had four sections in ''Cryptantha'': ''Eucryptantha'' (= ''Cryptantha''), ''Geocarya'', ''Krynitzkia'' (inclusive of ''Eremoc ...

Greeneocharis
''Greeneocharis'' is a genus of flowering plants in the family Boraginaceae. There are about 63 species and its native range extends from western U.S.A. down to northwestern Mexico and to western Argentina. It is part of subtribe of ''Amsinckiinae''. It was once thought to be a either a subgenus or synonym of ''Cryptantha'' , before being segregated out due to molecular phylogenetic analysis. Description It is an annual herb, with cushion-like, roots, which can have red-purple tinge. It has branches ascending to erect on a slender stem, generally strigose (having straight hairs all pointing in more or less the same direction). The leaves are sessile, arranged alternate and congested at the branch tips. They are linear, oblanceolate, or narrowly oblong (in shape) and hairy. The inflorescence is spike-like cymes. They have flower bracts. The flower consists of calyx lobes which are fused at base, and the tube is circumscissile in fruit (meaning it splits or opens along a circumfer ...

Boraginaceae
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Lee Greene
Edward Lee Greene (August 20, 1843–November 10, 1915) was an American botanist known for his numerous publications including the two-part ''Landmarks of Botanical History'' and the describing of over 4,400 species of plants in the American West. Early life Edward Lee Greene was born on August 20, 1843 in Hopkinton, Rhode Island. In 1859 Greene moved to Wisconsin and began studying at Albion Academy, a very reputable institution with a religious emphasis. There Greene met Thure Kumlien, a Swedish Naturalist with an interest in botany. Greene accompanied Kumlein on field trips, further developing Greene's interest in botany. In August 1862, Greene joined his father and brothers in joining the 13th Wisconsin Volunteer Infantry Regiment of the Union Army. Though he never rose above the rank of private in his three years of service, Greene was able to advance his botanical studies, collecting specimens as he marched through Tennessee, Kentucky and Alabama.

Alice Eastwood
__NOTOC__ Alice Eastwood (January 19, 1859 – October 30, 1953) was a Canadian American botanist. She is credited with building the botanical collection at the California Academy of Sciences, in San Francisco. She published over 310 scientific articles and authored 395 land plant species names, the fourth-highest number of such names authored by any female scientist. There are seventeen currently recognized species named for her, as well as the genera ''Eastwoodia'' and '' Aliciella''. Biography Alice Eastwood was born on January 19, 1859, in Toronto, Canada, to Colin Skinner Eastwood and Eliza Jane Gowdey Eastwood. When she was six her mother died. The children were cared for by various relatives, and for a time, Alice and her sister were placed at the Oshawa Convent in Toronto. The family reunited with their father and moved to Denver, Colorado, in 1873. In 1879, she graduated as valedictorian from East Denver High School.

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Dna Sequencing
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...
