Oreocarya Thompsonii 2
''Oreocarya'' (perennial cat's-eye) is a genus (biology), genus of flowering plants in the family (biology), 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 plant, perennial or Biennial plant, biennial, Herbaceous plant, plants. Most specie ... [...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. Following his re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johnstonella
''Johnstonella'' is a genus of flowering plants belonging to the family Boraginaceae. Its native range is south western and southern US 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 two species, and it has a disjunct distribution in the western United States and northwestern Mexico in North America and western Argentina in southern South America. 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 frui ...

Eremocarya
''Eremocarya'' is a genus of flowering plants in the family Boraginaceae. There are two species and its native range extends through the western United States and Texas to northwestern Mexico. It is part of subtribe of ''Amsinckiinae''. It was once thought to be an either a subgenus or synonym of ''Cryptantha'' , before being segregated out due to molecular phylogenetic analysis. Description A profusely branching annual herb with very slender, ascending, nearly leafless stems and the leaves are arranged in a basal rosette. The roots and the lower parts of the stems are often stained with a red, or purple hue.

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, thymine, cytosine, and guanine. 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, Genographic Project, 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 advancements in DNA seque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwin Blake Payson
Edwin Blake Payson (born Norwood, Colorado, February 18, 1893; died Denver, Colorado, May 15, 1927) was an American botanist. Early life Payson was the son of Amon R. Payson (1859–1938), a cattle rancher and one of the founders of Naturita, Colorado. Payson's mother Sarah Payson (1869–1893) died about a month after his birth. Payson went to Montrose High School in Montrose and then attended the University of Wyoming where he received a B.A. in 1917. Following graduation he entered the military, where he served in the 89th Infantry Division. He trained at Camp Funston, then returned to Laramie for his marriage to Louise Butler, a fellow botany student. After the end of World War I, Payson was an instructor at the American Expeditionary Forces University at Beaune, France. Payson returned to the United States in May of 1919. He was a teaching fellow at the Washington University in St. Louis school of botany and earned a M.A. (1920) and a PhD (1921) there. Career Payson t ...

Ivan Murray Johnston
I. M. (Ivan Murray) Johnston (February 28, 1898 – May 31, 1960) was a United States botanist. He studied at Pomona College in Claremont, California and at Harvard University. His plant collections are housed in the '' Rancho Santa Ana Botanic Garden'', in Claremont, and also in the Gray Herbarium of Harvard University. His areas of interest included Pteridophytes and Spermatophytes. Honours In 1925, German botanist August Brand, named a genus of flowering plants (belonging to the family Boraginaceae) from South America and the southern United States, as '' Johnstonella'' in Johnston's honour. Then in 1933, botanist O.E.Schulz named a genus of flowering plants (belonging to the family Brassicaceae), from Chile Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes, Andes Mountains and the Paci ... as '' Ivani ...
