Rupert Barneby
Rupert Charles Barneby (6 October 1911 – 5 December 2000) was a British-born self-taught botanist whose primary specialty was the Fabaceae (Leguminosae), the pea family, but he also worked on Menispermaceae and numerous other groups. He was employed by the New York Botanical Garden from the 1950s until shortly before his death. Barneby published prolifically and named and described over 1,100 new species. In addition, he had 25 species named after him as well as four genera: ''Barnebya,'' ''Barnebyella'', ''Barnebydendron'', and '' Rupertia''. He received numerous prestigious botanical awards, including The New York Botanical Garden's Henry Allan Gleason Award (1980), the American Society of Plant Taxonomists' Asa Gray Award (1989), the International Association for Plant Taxonomy's Engler Silver Medal (1992), and the International Botanical Congress's Millennium Botany Award (1999).

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Physaria
''Physaria'' is a genus of flowering plants in the family Brassicaceae. Many species are known generally as twinpods, bladderpods, or lesquerella. They are native to the Americas, with many species endemic to western North America. They are densely hairy annual and perennial herbs often growing prostrate or decumbent, along the ground in patches or clumps. They bear inflorescences of bright yellow flowers. The fruit is often notched deeply, dividing into twin sections, giving the genus its common name. Bladderpod oil is extracted from the seeds of ''Physaria fendleri'' and certain other species in the genus. U.S. Fish and Wildlife Service: Missouri Bladderpod 5-Year Review (2008) Due to the presence of both annual and perennial herbaceous members, this genus has been used as a model for allocation pattern comparisons ...

Phlox Tumulosa
''Phlox'' (; Greek φλόξ "flame"; plural "phlox" or "phloxes", Greek φλόγες ''phlóges'') is a genus of 67 species of perennial and annual plants in the family Polemoniaceae. They are found mostly in North America (one in Siberia) in diverse habitats from alpine tundra to open woodland and prairie. Some flower in spring, others in summer and fall. Flowers may be pale blue, violet, pink, bright red, or white. Many are fragrant. Description The name is derived from the Greek word ''phlox'' meaning flame in reference to the intense flower colors of some varieties. Fertilized flowers typically produce one relatively large seed. The fruit is a longitudinally dehiscent capsule with three or more valves that sometimes separate explosively. Some species such as '' P. paniculata'' (garden phlox) grow upright, while others such as '' P. subulata'' (moss phlox, moss pink, mountain phlox) grow short and matlike. Paniculata or tall phlox, is a native American wildflower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eriogonum Shockleyi
''Eriogonum'' is a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers such as the California buckwheat (''Eriogonum fasciculatum''). The genus derived its name from the Greek word ''erion'' meaning 'wool' and ''gonu'' meaning 'knee or joint'. The author of the genus, Michaux, explained the name as describing the first named species of the genus (''E. tomentosum'') as a wooly plant with sharply bent stems (''"planta lanata, geniculata"''). Despite sharing the common name "buckwheat", ''Eriogonum'' is part of a different genus than the cultivated European buckwheat and than other plant species also called wild buckwheat. It came into the news in 2005 when the Mount Diablo buckwheat (''Eriogonum truncatum'', believed to be extinct) was rediscovered. Ecology ''Eriogonum'' speci ...
