Fremontodendron
''Fremontodendron'', with the common names fremontia and flannelbush or flannel bush, is a genus of three known species of shrubs native to the Southwestern United States and northwest Mexico. Taxonomy They are within the botanical family Malvaceae. Formerly they were treated within the Sterculiaceae, tribe Fremontodendreae, together with the genus '' Chiranthodendron''. The genus ''Fremontodendron'' was named in dedication to John C. Frémont, who first collected it during an 1846 expedition to Alta California. Description The leaves have a leathery and fuzzy texture reminiscent of flannel (hence the name), and the yellow to orange flowers are large and showy. The leaves and young shoots can cause skin and eye irritation. Species There are three species: * ''Fremontodendron californicum'' — Californian flannelbush * '' Fremontodendron decumbens'' (R. Lloyd) — Pine Hill flannelbush :: A decumbent and low spreading form, in height and in width, has yellow-orange fl ...

Fremontodendron Mexicanum
''Fremontodendron mexicanum'' is a rare species of shrub in the mallow family known by the common names Mexican flannelbush, Mexican fremontia, and Southern flannelbush, that is endemic to the central Peninsular Ranges in Mexico and the United States. Distribution The species is known from about ten occurrences in northern Baja California state and adjacent southern San Diego County, California. However, it has most recently been confirmed to exist in only two of those locales currently. In 1993, fewer than 100 individuals were thought to exist. In the United States it is a federally listed endangered species. Ecology The shrub grows generally on alluvial plains, in California montane chaparral and woodlands and temperate coniferous forest habitats, among Tecate cypress (''Cupressus forbesii'') trees. Description ''Fremontodendron mexicanum'' is an erect, flowering shrub or multi-trunked small tree reaching high, with branches spreading to wide. The leathery and furry o ...

Pine Hill Ecological Reserve
Pine Hill Ecological Reserve is a nature reserve of located due east of Folsom Lake in the Sierra Nevada foothills, in El Dorado County, California. The reserve was established in 1979, and is managed by the Bureau of Land Management. The Pine Hill Ecological Reserve is one unit of the much larger Pine Hill Preserve system that consists of five separate units of varying size that total more than and protects eight rare plants and their gabbro soil habitat. It is jointly managed by several local, state and federal agencies through a Cooperative Management Agreement. History Preservation efforts started in 1977, when surplus lands managed by the California Department of Forestry were to be disposed of in the Pine Hill area. Environmental groups joined to urge the state to set aside significant natural areas from development and by 1979, the summit of Pine Hill became a state-owned ecological reserve of . In 1991, were added by the Bureau of Land Management (BLM), and in 2002 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ...

Sterculiaceae
Sterculiaceae was a family of flowering plant based on the genus ''Sterculia''. Genera formerly included in Sterculiaceae are now placed in the family Malvaceae, in the subfamilies: Byttnerioideae, Dombeyoideae, Helicteroideae and Sterculioideae. As traditionally circumscribed the Sterculiaceae, Malvaceae, Bombacaceae, and Tiliaceae comprise the "core Malvales" of the Cronquist system and the close relationship among these families is generally recognized. Sterculiaceae may be separated from Malvaceae ''sensu stricto'' by the smooth surface of the pollen grains and the bilocular anthers. Numerous phylogenetic studies have revealed that Sterculiaceae, Tiliaceae and Bombacaceae as traditionally defined are cladistically polyphyletic. The APG and APG II systems unite Bombacaceae, Malvaceae ''sensu stricto'', Sterculiaceae and Tiliaceae into a more widely circumscribed Malvaceae, i.e., Malvaceae ''sensu lato''. In that view the taxa formerly classified in Sterculiaceae are treated in t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gabbro
Gabbro () is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine-grained basalt. Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ridges. Gabbro is also found as plutons associated with continental volcanism. Due to its variant nature, the term ''gabbro'' may be applied loosely to a wide range of intrusive rocks, many of which are merely "gabbroic". By rough analogy, gabbro is to basalt as granite is to rhyolite. Etymology The term "gabbro" was used in the 1760s to name a set of rock types that were found in the ophiolites of the Apennine Mountains in Italy. It was named after Gabbro, a hamlet near Rosignano Marittimo in Tuscany. Then, in 1809, the German geologist Christian Leopold von Buch used the term more restrictively in his descri ...

Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils ...
