Phyllodoce Empetriformis
''Phyllodoce empetriformis'', also known as pink mountain heather, gets its name from its red and pink bell-shaped flowers. It is found along the Rocky Mountains of the Northwestern United States and Western Canada. ''Phyllodoce empetriformis'' is a low matting shrub with distinctive leaves which are pine needle like. It bears attractive flowers in shades of pink and purple. It is one of the parents of the artificial hybrid × ''Phyllothamnus erectus'', the other being '' Rhodothamnus chamaecistus''. Description This common evergreen alpine shrub bears its red-purple flower clustered at the end of the stem. The flowers of the ''Phyllodoce empetriformis'' can grow in clusters of many to as little as one. The leaves alternate on the stem and roll under themselves so tightly they resemble pine needles. It is a fairly short shrub that grows from 10–40 cm tall. The dwarf shrub can survive in subalpine to alpine regions because of their ability to minimize water loss through ...

James Edward Smith (botanist)
Sir James Edward Smith (2 December 1759 – 17 March 1828) was an English botanist and founder of the Linnean Society. Early life and education Smith was born in Norwich in 1759, the son of a wealthy wool merchant. He started studying botanical science when he was eighteen. In 1781 he enrolled in the medical course at the University of Edinburgh, where he studied chemistry under Joseph Black, natural history under John Walker, and botany under John Hope, an early teacher of Linnaean taxonomy. He moved to London in 1783 to continue his studies and became a friend of Sir Joseph Banks, who was offered the entire collection of books, manuscripts and specimens of the Swedish natural historian and botanist Carl Linnaeus following the death of his son Carolus Linnaeus the Younger. Banks declined the purchase, but Smith borrowed money from his father and bought the collection for the price of £1,000 in 1784. Smith was elected a Fellow of the Royal Society in 1785.

Sediment
Sediment is a solid material that is transported to a new location where it is deposited. It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently sediment transport, transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension (chemistry), suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification. Sediments are most often transported by water (fluvial, fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and stream channel, river channel deposits are examples of fluvial transport and deposition (geology), deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of California
California native plants are plants that existed in California prior to the arrival of European colonialism, European explorers and colonists in the late 18th century. California includes parts of at least three Phytochorion, phytochoria. The largest is the California Floristic Province, a geographical area that covers most of California, portions of neighboring Oregon, Nevada, and Baja California, and is regarded as a "world hotspot" of biodiversity. Introduction In 1993, ''The Jepson Manual'' estimated that California was home to 4,693 native species and 1,169 native subspecies or varieties, including 1,416 endemic species. A 2001 study by the California Native Plant Society estimated 6,300 native plants. These estimates continue to change over time. Of California's total plant population, 2,153 species, subspecies, and varieties are endemism, endemic and native to California alone, according to the 1993 Jepson Manual study. This botanical diversity stems not only from the si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Alaska
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and ...

Ericoideae
Ericoideae is a subfamily of Ericaceae, containing nineteen genera, and 1,790 species, the largest of which is ''Rhododendron'', followed by Erica. The Ericoideae bear spiral leaves with flat laminae. The pedicel is articulated and the flowers are pendulous or erect, and monosymmetric, with an abaxial median sepal. The carpels are free and the anthers lack appendages. The capsule is septicidal.

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berry
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit although many pips or seeds may be present. Common examples of berries in the culinary sense are strawberries, raspberries, blueberries, blackberries, white currants, blackcurrants, and redcurrants. In Britain, soft fruit is a horticultural term for such fruits. The common usage of the term "berry" is different from the scientific or botanical definition of a berry, which refers to a fleshy fruit produced from the ovary of a single flower where the outer layer of the ovary wall develops into an edible fleshy portion( pericarp). The botanical definition includes many fruits that are not commonly known or referred to as berries, such as grapes, tomatoes, cucumbers, eggplants, bananas, and chili peppers. Fruits commonly considered berries but excluded by the botanical definition include strawberries, raspber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empetrum Nigrum
''Empetrum nigrum'', crowberry, black crowberry, mossberry, or, in western Alaska, Labrador, etc., blackberry, is a flowering plant species in the heather family Ericaceae with a near circumboreal distribution in the Northern Hemisphere.

Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by Solvation, dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...
