Osoberry
''Oemleria'' is a small genus in the rose family native to the Pacific coast areas of North America. It includes one living species, '' Oemleria cerasiformis'' and one species described from Washington state fossils, '' Oemleria janhartfordae''. ''Oemleria'' forms the monophyletic tribe Exochordeae with the genera ''Exchorda'' and ''Prinsepia'', which is placed in the subfamily Amygdaloideae Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that ....

Oemleria Cerasiformis
''Oemleria cerasiformis'', a shrub commonly known as osoberry, squaw plum, Indian plum, or Indian Peach, is the sole extant species in the genus '' Oemleria''. The deciduous and perennial shrub can grow up to 7 meters tall, with spreading branches that produce small white flowers and bitter fruit that only become sweet when fully ripe. Osoberry is dioecious, only female plants producing fruit, while males produce a high reproductive biomass of pollen and flowers. The flowers are insect and hummingbird-pollinated and the fruits are consumed by both birds and mammals, which later disperse the seeds in their droppings ( endozoochory). Fossil records indicate that the species had a similar range during the Eocene epoch. It is native to the Pacific coast and coast ranges of North America, from British Columbia, Canada, to Santa Barbara County, California. Its favored habitat conditions include full sun, moist soil, and low elevation. It is one of the first plants to have its flowers ...

Oemleria Janhartfordae
''Oemleria janhartfordae'' is an extinct species of osoberry in the family Rosaceae. It was described from a single fossil flower found in the Okanagan Highlands of Washington state. The species has been used as a dating point for both the rose family and the rose family tribe Exochordeae. Distribution The ''Oemleria janhartfordae'' fossil was recovered from a single site in the Eocene Okanagan Highlands of Central British Columbia and northeast central Washington state. The single described specimen is from the Klondike Mountain Formation in Northern Ferry County, Washington, being recovered from the "Boot Hill" site B4131 in Republic, Washington. Early estimates of the highlands sites ranged from Miocene to Eocene in age. The age of the Klondike Mountain Formation was debated for many years, with plant fossils suggesting a Late Oligocene or Early Miocene age, and the first descriptions of species from the area included them in the Middle Miocene Latah Formation.

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rosaceae
Rosaceae (), the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus '' Rosa''. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes popular ornamental trees and shrubs, such as roses, meadowsweets, rowans, firethorns, and photinias. Among the most species-rich genera in the family are '' Alchemilla'' (270), '' Sorbus'' (260), ''Crataegus'' (260), '' Cotoneaster'' (260), '' Rubus'' (250), and ''Prunus'' (200), which contains the plums, cherries, peaches, apricots, and almonds. However, all of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pacific Coast
Pacific coast may be used to reference any coastline that borders the Pacific Ocean. Geography Americas North America Countries on the western side of North America have a Pacific coast as their western or south-western border. One of the notable exceptions is Panama, where the Pacific coast is primarily on its southern border. The first Europeans to see the Pacific Ocean were able to do so by crossing the narrow Isthmus of Panama. The unique position of Panama in relation to the Pacific Ocean resulted in the ocean initially being named the South Sea. * British Columbia Coast, West Coast of Canada * Geography of Costa Rica * Geography of El Salvador * Geography of Guatemala * Geography of Honduras * Pacific Coast of Mexico * Geography of Nicaragua * Geography of Panama * West Coast of the United States ** Geography of Alaska South America Only four countries in South America have a Pacific coast as a part (or all) of their border. * Geography of Chile * Geography of C ...

Amygdaloideae
Amygdaloideae is a subfamily within the flowering plant family Rosaceae. It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used. Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic. To solve this problem, a larger subfamily was defined that includes the former Amygdaloideae, Spiraeoideae, and Maloideae. This subfamily, however, is to be called Amygdaloideae rather than Spiraeoideae under the International Code of Nomenclature for algae, fungi, and plants as updated in 2011. As traditionally defined, the Amygdaloideae includes such commercially important crops as plum, cherry, apricot, peach, and almond. The fruit of these plants are known as stone fruit ( drupes), as each fruit contains a hard shell (the endocarp) called a ''stone'' or ''pit'', which contains the single seed. The expanded definition of the Amygdaloideae adds to these commer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
