Penstemon Ambiguus
''Penstemon ambiguus'', commonly known as the bush penstemon, pink plains penstemon, or gilia beardtongue is a species of ''Penstemon'' that grows in the shortgrass prairies and deserts of the western United States and northern Mexico. This bush like penstemon grows in sandy, loose, and creosote soils and is particularly known for the spectacular flowering show it produces, sometime seasons turning whole hillsides bright pink–white. Description ''Penstemon ambiguus'' is a perennial, somewhat bushy species with stems that are woody at their base ( suffrutescent). The stems are generally 30–40 cm tall, but will sometimes be as short as 20 cm or as tall as 60 cm, and are either smooth or somewhat rough near the base. They have paired leaves that taper from base to the tip, most often 5–30 mm long and only 0.5–1 mm wide, but occasionally as wide as 2.5 mm and as short as 3 mm or as long as 40 mm. The edges of the leaves are either smoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Torrey
John Torrey (August 15, 1796 – March 10, 1873) was an American botany, botanist, chemist, and physician. Throughout much of his career, he was a teacher of chemistry, often at multiple universities, while he also pursued botanical work, focusing on the flora of North America. His most renowned works include studies of the New York flora, the Mexican Boundary, the Pacific railroad surveys, and the uncompleted ''Flora of North America''. Biography Torrey was born in New York City, the second child of Capt. William and Margaret (née Nichols) Torrey.Robbins, C. C. (1968). John Torrey (1796–1873), His Life & Times.

Autonym (botany)
In botanical nomenclature, autonyms are automatically created names, as regulated by the ''International Code of Nomenclature for algae, fungi, and plants'' that are created for certain subdivisions of genera and species, those that include the type of the genus or species. An autonym might not be mentioned in the publication that creates it as a side-effect. Autonyms "repeat unaltered" the genus name or species epithet of the taxon being subdivided, and no other name for that same subdivision is validly published (article 22.2). For example, ''Rubus'' subgenus ''Eubatus'' is not validly published, and the subgenus is known as ''Rubus'' subgen. ''Rubus''. Autonyms are cited without an author. The publication date of the autonym is taken to be the same as that of the subdivision(s) that automatically established the autonym, with some special provisions (the autonym is considered to have priority over the other names of the same rank established at the same time (article 11.6)).

Flora Of Chihuahua (state)
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USDA Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Creosote Bush
''Larrea tridentata'', called creosote bush and greasewood as a plant, chaparral as a medicinal herb, and ''gobernadora'' (Spanish language, Spanish for "governess") in Mexico, due to its ability to secure more water by inhibiting the growth of nearby plants. In Sonora, it is more commonly called ''hediondilla''; Spanish ''hediondo'' = "smelly". It is a flowering plant in the family Zygophyllaceae. The specific name ''tridentata'' refers to its three-toothed leaves. Distribution ''Larrea tridentata'' is a prominent species in the Mojave Desert, Mojave, Sonoran Desert, Sonoran, and Chihuahuan Desert, Chihuahuan Deserts of western North America, and its range includes those and other regions in portions of southeastern California, Arizona, southern Nevada, southwestern Utah, New Mexico, and Texas in the United States, and Chihuahua (state), Chihuahua, Sonora, Coahuila, Nuevo León, Zacatecas, Durango and San Luis Potosí, San Luis Potosì in Mexico.

Palmer Divide
Named after Colorado Springs founder William Jackson Palmer, the Palmer Divide is a caprock escarpment style ridge in central Colorado that separates the Arkansas River basin from the South Platte basin. It extends from the Front Range of the Rockies in central Colorado eastward approximately 80 miles toward the town of Limon. The western end of the Palmer Divide is popularly considered to be at Palmer Lake, located south of Denver and north of Colorado Springs. However, the divide between the two river basins actually extends west and then north to a junction with the Continental Divide at McNamee Peak. For much of its length, it travels very roughly along the northern border of El Paso County. Thus, it forms a natural separator between the Denver and Colorado Springs metropolitan areas. The elevation along the divide varies between about , with the high point being Bald Mountain in southern Douglas County. This peak can be seen from I-25 just northeast of Monument Hill. This ...

Natural Resources Conservation Service
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers. Its name was changed in 1994 during the presidency of Bill Clinton to reflect its broader mission. It is a relatively small agency, currently comprising about 12,000 employees. Its mission is to improve, protect, and conserve natural resources on private lands through a cooperative partnership with state and local agencies. While its primary focus has been agricultural lands, it has made many technical contributions to soil surveying, classification, and water quality improvement. One example is the Conservation Effects Assessment Project (CEAP), set up to quantify the benefits of agricultural conservation efforts promoted and supported by programs in the Farm Security and Rural Investment Act of 2002 (2002 Farm Bill).
