Cryptantha Circumscissa
''Greeneocharis circumscissa'' is a species of flowering plant in the borage family, known by the common name cushion cryptantha. It is native to western North America from Washington to Baja California to Colorado and it is also found in Argentina. It grows in sandy or gravelly types of habitat, from mountains to desert, below above sea level.Philip Alexander Munz This is an annual herb producing a short, bristly, multi-branched stem tangled into a mat no more than 10 centimeters tall. It grows from a red taproot which dries purple. The leaves are up to 1.5 centimeters long, linear to widely lance-shaped, and densely hairy to bristly. The inflorescence is a length of developing fruits with a dense cluster of up to 5 flowers at the tip. The flower has a five-lobed white corolla with yellow appendages at the top of its tube.

William Jackson Hooker
Sir William Jackson Hooker (6 July 178512 August 1865) was an English botanist and botanical illustrator, who became the first director of Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. Hooker was born and educated in Norwich. An inheritance gave him the means to travel and to devote himself to the study of natural history, particularly botany. He published his account of an expedition to Iceland in 1809, even though his notes and specimens were destroyed during his voyage home. He married Maria, the eldest daughter of the Norfolk banker Dawson Turner, in 1815, afterwards living in Halesworth for 11 years, where he established a herbarium that became renowned by botanists at the time. He held the post of Regius Professor of Botany at Glasgow University, where he worked with the botanist and lithographer Thomas Hopkirk and enjoyed the supportive friendshi ...

Ivan Murray Johnston
I. M. (Ivan Murray) Johnston (February 28, 1898–May 31, 1960), was a United States Botany, 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, were, among others: Fern, Pteridophytes, Spermatophytes Honours In 1925, German botanist August Brand, named a genus of flowering plants (belonging to the family Boraginaceae), from South America and southern states in USA, as ''Johnstonella'' in his honour. Then in 1933, botanist O.E.Schulz named a genus of flowering plants (belonging to the family Brassicaceae), from Chile as ''Ivania (plant), Ivania''. In 1936, botanist Hsen Hsu Hu published ''Sinojohnstonia'', which is a genus of flowering plants from China, belonging to the family Boraginaceae.

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] |

Colorado
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Philip Alexander Munz
Philip Alexander Munz (1892–1974) was an American botanist, plant taxonomist and educator who worked at the Rancho Santa Ana Botanic Garden and was a professor of botany at Pomona College, serving as dean there for three years. In 1935 Munz published his ''Manual of Southern California Botany''. Munz compiled the voluminous '' A California Flora'' with David D. Keck, published by the University of California Press in 1959, and with a supplement published in 1968. Munz published ''A California Flora'' without any research support and with a relatively small subvention for publication from the University of California Press. In 1974, his book ''A Flora of Southern California'' was published posthumously, with the botanical families presented in an alphabetical order. List of selected publications Munz authored four popular plant guides for general readers interested in botany but untrained in plant taxonomy Plant taxonomy is the science that finds, identifies, describes, cla ...

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taproot
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable. The taproot system contrasts with the adventitious or fibrous root system of plants with many branched roots, but many plants that grow a taproot during germination go on to develop branching root structures, although some that rely on the main root for storage may retain the dominant taproot for centuries, for example ''Welwitschia''.Taproot also store nutrition. Plants with taproots are often vegetables. Description Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot, which is one main root forming from the enlarging radicle of the seed. The tap root can be persistent throughout the life of the plant but is most oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...
