Thelesperma Filifolium
''Thelesperma filifolium'', commonly known as stiff greenthread, or plains greenthread, is a species of flowering plant in the aster family, Asteraceae. It is often found growing in shallow soils. It prefers disturbed sites in dry, sandy or gravelly soil with a neutral to basic pH. Stiff greenthread adapts to various soil conditions, including loam, clay, caliche, and roadsides. It blooms between March and June and often into the fall. Distribution In Texas, stiff greenthread can be found growing along roadsides and on dry hills in the South Plains and Edwards Plateau regions. The herb grows over much of the plains and mountain states, reaching up to Wyoming, Montana, Nebraska and South Dakota. It grows prolifically on the Navajo, Hopi, and Pueblo lands, as well as throughout much of New Mexico, Arizona and Colorado. Description Having a taproot, it is extremely resistant to drought, but thrives in rain. The designation greenthread is most appropriate, as it has thin, thread ...

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 ...

South Dakota
South Dakota (; Sioux language, Sioux: , ) is a U.S. state in the West North Central states, North Central region of the United States. It is also part of the Great Plains. South Dakota is named after the Lakota people, Lakota and Dakota people, Dakota Sioux Native Americans in the United States, Native American tribes, who comprise a large portion of the population with nine Indian reservation, reservations currently in the state and have historically dominated the territory. South Dakota is the List of U.S. states and territories by area, seventeenth largest by area, but the List of U.S. states and territories by population, 5th least populous, and the List of U.S. states and territories by population density, 5th least densely populated of the List of U.S. states, 50 United States. As the southern part of the former Dakota Territory, South Dakota became a state on November 2, 1889, simultaneously with North Dakota. They are the 39th and 40th states admitted to the union; Pr ...

Coreopsideae
Coreopsideae is a tribe of flowering plants belonging to the Asteroideae subfamily. It includes widely cultivated genera such as ''Cosmos'' and ''Dahlia''. A similar group has been recognized since 1829, generally as part of the tribe Heliantheae ( Cassini, 1819). In the late 20th century, molecular studies caused a slightly redefined version of this group to be recognized as its own tribe, Coreopsideae. The larger version of Heliantheae was split into tribes including Bahieae, Chaenactideae, Coreopsideae, Helenieae and, finally, Heliantheae (''sensu stricto''). Within the tribe, the traditional definition of genera based on flower and fruit characters does not reflect evolutionary relationships as inferred through molecular phylogenetics. The tribe is characterized by shiny green bracts at the base of the flower head in two rows: an inner row of tightly spaced bracts and an outer row of a smaller number pointing downward. It includes five genera that use carbon fixation: '' Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulphur Butterfly
Coliadinae, the sulphurs or yellows, are a subfamily of butterflies with about 300 described species. There are 36 species in North America, where they range from Mexico to northern Canada. In most species, males are easily distinguished from females. For example, in the genera ''Colias'' and ''Gonepteryx''), males exhibit brilliant UV reflections that the females lack. Systematics The Coliadinae can be arranged in the three traditional tribes and a basal lineage, with one genus of unclear placement. The taxa—including some selected species—are arranged here in the presumed phylogenetic sequence, from the most ancient lineages to the most modern ones:Brower (2006) Basal lineage * '' Kricogonia'' Reakirt, 1863 * '' Nathalis'' Boisduval, 836/small> Euremini * ''Terias'' Swainson, 1821 * '' Pyrisitia'' Butler, 1870 * '' Abaeis'' Hübner, 819/small> * ''Eurema'' Hübner, 819/small> – grass yellows * '' Leucidia'' Doubleday, 847/small> * ''Teriocolias'' Roeber 1 ...

Painted Bunting
The painted bunting (''Passerina ciris'') is a species of bird in the cardinal family, Cardinalidae. It is native to North America. The bright plumage of the male only comes in the second year of life; in the first year they can only be distinguished from the female by close inspection. Taxonomy The painted bunting was originally described by Carl Linnaeus in his eighteenth-century work ''Systema Naturae''. There are two recognized subspecies of the painted bunting. * ''P. c. ciris'' – (Linnaeus, 1758): nominate, breeds in the southeastern United States * ''P. c. pallidior'' – Mearns, 1911: breeds in south central US and northern Mexico The painted bunting is also called the Mexican canary, painted finch, pope, or nonpareil. Description The male painted bunting is often described as the most beautiful bird in North America and as such has been nicknamed nonpareil, or "without equal". Its colors, dark blue head, green back, red rump, and underparts, make it extremely eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phyllary
In botanical terminology, a phyllary, also known an involucral bract or tegule, is a single bract of the involucre of a composite flower. The involucre is the grouping of bracts together. Phyllaries are reduced leaf-like structures that form one or more whorls immediately below a flower head. Function Phyllaries provide protection to developing flowers and fruits. In the dandelion hybrid ''Taraxacum japonicum'' × ''officinale'', recurved phyllaries help defend the flowers from herbivory by slugs. They sometimes assist in the dispersal of fruits. The hooked phyllaries of burdock species (''Arctium'') cling to the fur and feathers of animals, dispersing the seeds away from the parent plant (exozoochory). Structure and arrangement Phyllary morphology is useful in plant identification as between species of the Asteraceae The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales.

Bellis Perennis
''Bellis perennis'' (), the daisy, is a European species of the family Asteraceae, often considered the archetypal species of the name daisy. To distinguish this species from other plants known as daisies, it is sometimes qualified as common daisy, lawn daisy or English daisy. Description ''Bellis perennis'' is a perennial herbaceous plant growing to in height. It has short creeping rhizomes and rosettes of small rounded or spoon-shaped leaves that are from long and grow flat to the ground. The species habitually colonises lawns, and is difficult to eradicate by mowing, hence the term 'lawn daisy'. It blooms from March to September and exhibits the phenomenon of heliotropism, in which the flowers follow the position of the sun in the sky. The flowerheads are composite, about in diameter, in the form of a pseudanthium, consisting of many sessile flowers with white ray florets (often tipped red) and yellow disc florets. Each inflorescence is borne on a single leafless stem , ... [...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] |
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] |
