Cylindropuntia × Deserta
''Cylindropuntia'' is a genus of cacti (family Cactaceae), containing species commonly known as chollas, native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant. Taxonomy ''Cylindropuntia'' was formerly treated as a subgenus of ''Opuntia'', but have now been separated based on their cylindrical stems (''Opuntia'' species have flattened stems) and the presence of papery epidermal sheaths on the spines (''Opuntia'' has no sheaths). A few species of mat- or clump-forming opuntioid cacti are currently placed in the genus ''Grusonia''. Collectively, opuntias, chollas, and related plants are sometimes called opuntiads. The roughly 35 species of ''Cylindropuntia'' are native to the southwestern and south-central United States, Mexico ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

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. ''Bulletin of the Torrey Botanical Club''. Vol. 95, No. Nov. 6–Dec. 1968, 515–645. Torrey Botanical Club, New York. He showed a fondness for mechanics, and at one time planned to become a machinist. When he was 15 or 16, his father received an appointment to the state prison at Greenwich Village, New York, where he was tutored by Amos Eaton, then a pri ...

Cylindropuntia Californica
''Cylindropuntia californica'' is a species of cholla cactus known by the common name snake cholla. It is primarily found in Baja California, Mexico and the southernmost part of California in the United States. It is characterized by a short, decumbent habit, yellow-green flowers, elongated stems, and short spines. It is mostly found in coastal sage scrub and coastal chaparral habitats, but two varieties in Baja California can be found in foothills and deserts. In California, variety ''californica'' is regarded as a rare and threatened plant, with a California Native Plant Society listing of 1B.1, in part due to its limited number of occurrences and threats from development. It formerly had a larger range due to the inclusion of '' Cylindropuntia bernardina'' within it as the variety ''parkeri''. Description A short, sprawling cactus, this species is typically found growing less than high. There are usually several to many trunks, with the main branches and stems usually sprawl ...

Cylindropuntia Bigelovii
''Cylindropuntia bigelovii'', the teddy-bear cholla ''(choy-ya''), is a cholla cactus species native to Northwestern Mexico, and to the United States in California, Arizona, and Nevada. Description ''Cylindropuntia bigelovii'' has a soft appearance due to its solid mass of very formidable spines that completely cover the stems, leading to its sardonic nickname of "teddy bear" or "jumping teddy bear". The teddy-bear cholla stands tall with a distinct trunk. The branches or lobes are at the top of the trunk and are nearly horizontal. Lower branches typically fall off, and the trunk darkens with age. The silvery-white spines, which are actually a form of leaf, almost completely obscure the stem with a fuzzy-looking but impenetrable defense. The spines are long and covered with a detachable, paper-like sheath. The yellow-green flowers emerge at the tips of the stems in May and June. Flowers are usually in length and produce fruit that is in diameter, tuberculate, and may or m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
