''Cochemiea thornberi'' is a species of cactus known by the common names Thornber's fishhook cactus and Thornber's nipple cactus. It is native to Arizona in the United States and Sonora in Mexico.''Mammillaria thornberi''. The Nature Conservancy.''Mammillaria thornberi''. Flora of North America. This plant has numerous branches that all root in the ground, forming a clump of rooted stems all belonging to one plant.

Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

Flora Of Sonora
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] |

Cochemiea
''Cochemiea'' is a genus of cactus. It has previously been synonymized with ''Mammillaria'', but molecular phylogenetic studies have shown that when broadly circumscribed, ''Mammillaria'' is not monophyletic, and ''Cochemiea'' has been accepted as a separate genus. Taxonomy A 2021 molecular phylogenetic study of the "mammilloid clade", which included the genera ''Cochemiea'', ''Coryphantha'', ''Cumarinia'', ''Escobaria'', ''Mammillaria'', ''Neolloydia'' and ''Ortegocactus'', showed that it consisted of four monophyletic groups, which the authors re-circumscribed into four genera: '' Cumarinia''; ''Mammillaria'', with a reduced number of species; ''Coryphantha'', expanded to include species previously placed in ''Mammillaria'' and ''Escobaria''; and ''Cochemiea'', expanded to include a large number of species previously placed in ''Mammillaria'', as well as ''Neolloydia conoidea''. Species In 2021, Breslin, Wojciechowski and Majure placed the following species in the genus, some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saguaro National Park
Saguaro National Park is an American national park in Pima County, southeastern Arizona. The park consists of two separate areas—the Tucson Mountain District (TMD) about west of the city of Tucson and the Rincon Mountain District (RMD) about east of the city—that preserve Sonoran Desert landscapes, fauna, and flora, including the giant saguaro cactus. The volcanic rocks on the surface of the Tucson Mountain District differ greatly from the surface rocks of the Rincon Mountain District; over the past 30 million years, crustal stretching displaced rocks from beneath the Tucson Mountains of the Tucson Mountain District to form the Rincon Mountains of the Rincon Mountain District. Uplifted, domed, and eroded, the Rincon Mountains are significantly higher and wetter than the Tucson Mountains. The Rincons, as one of the Madrean Sky Islands between the southern Rocky Mountains and the Sierra Madre Oriental in Mexico, support high biodiversity and are home to many plants and anim ...

Avra Valley
The Avra Valley is a 50-mile (80 km) long northwest–southeast valley, bordering the west of Tucson, Arizona. The Tucson Mountains are at the valley's center-east, with suburbs ranging east of the Tucson Mountains and trending northwest to the Avra Valley's northeast. This entire northwest stretch from Tucson contains the northwest trending Interstate 10, the route to Casa Grande and Phoenix. The northeast of the valley contains Marana on I-10, the Pinal Airpark, an aircraft storage park, and other communities along I-10. Avra Valley Airport is a general aviation airport in Marana, located about 15 miles (24 km) northwest of Tucson and being used for storage of classic propeller-era airliners. The center-(west) of the valley is at Cocoraque Butte, , extended northeast from the Roskruge Mountains. Cocoraque Butte's height is .''Arizona Road & Recreation Atlas'', pp. 52–52.

Ambrosia Dumosa
''Ambrosia dumosa'', the burro-weed or white bursage, a North American species of plants in the family Asteraceae. It is a common constituent of the creosote-bush scrub community throughout the Mojave desert of California, Nevada, and Utah and the Sonoran Desert of Arizona and northwestern Mexico (Baja California, Baja California Sur, Sonora, Chihuahua). ''Ambrosia dumosa'' has been studied to determine allelopathic interactions with creosote bush, ''Larrea tridentata'', which produces a chemical that inhibits the growth of ''A. dumosa.'' Other studies have suggested that ''A. dumosa'' roots produce a chemical that causes them to grow away from conspecific roots, preventing competition for water resources. In addition to burro-weed, ''A. dumosa'' is also commonly called white bursage, and burrobush. Description ''Ambrosia dumosa'', a form of ragweed, is a highly branched shrub 20 to 90 cm in height. The younger stems are covered with soft gray-white hairs. Approximately ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
