Cylindropuntia × Pallida
''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, Me ... [...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 ...
