Indigenous (ecology)
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

Ornithogalum Umbellatum
''Ornithogalum umbellatum'', the garden star-of-Bethlehem, grass lily, nap-at-noon, or eleven-o'clock lady, a species of the genus ''Ornithogalum'', is a perennial bulbous flowering plant in the asparagus family (Asparagaceae). ''O. umbellatum'' is a relatively short plant, occurring in tufts of basal linear leaves, producing conspicuous white flowers, in a stellate pattern, in mid to late spring. The flowers open late in the day (hence some of its common names), but when closed have a green stripe on the outside. It is native throughout most of southern and central Europe, and north-western Africa. ''O. umbellatum'' is often grown as a garden ornamental, but in North America and other areas it has escaped cultivation and can be found in many areas, where it may become an invasive noxious weed. Parts of the plant are considered poisonous, but are used in some regional cuisines. Essences are also sold as patent remedies. ''O. umbellatum'' has been depicted in art by artists s ...

Alnus Rhombifolia
''Alnus rhombifolia'', the white alder, is an alder tree native to western North America, from British Columbia and Washington east to western Montana, southeast to the Sierra Nevada, and south through the Peninsular Ranges and Colorado Desert oases in Southern California. It occurs in riparian zone habitats at an altitudes range of .Flora of North America''Alnus rhombifolia''/ref> While not reported in northern Baja California, it has been predicted on the basis of its climatic adaptation to occur there also. ''Alnus rhombifolia'' is primarily found in the chaparral and woodlands, montane, and temperate forests ecoregions. Description ''Alnus rhombifolia'' is a medium-sized deciduous tree growing to (rarely to ) tall, with pale gray bark, smooth on young trees, becoming scaly on old trees. The leaves are alternate, rhombic to narrow elliptic, long and broad, with a finely serrated margin and a rounded to acute apex; they are thinly hairy below.http://calphotos.berkeley.edu/cg ...

Alnus Incana
''Alnus incana'', the grey alder or speckled alder, is a species of multi-stemmed, shrubby tree in the birch family, with a wide range across the cooler parts of the Northern Hemisphere. Tolerant of wetter soils, it can slowly spread with runners and is a common sight in swamps and wetlands. It is easily distinguished by its small cones, speckled bark and broad leaves. Description It is a small- to medium-sized tree tall with smooth grey bark even in old age, its life span being a maximum of 60 to 100 years. The leaves are matte green, ovoid, long and broad. The flowers are catkins, appearing early in spring before the leaves emerge, the male catkins pendulous and long, the female catkins long and one cm broad when mature in late autumn. The seeds are small, long, and light brown with a narrow encircling wing. The grey alder has a shallow root system, and is marked not only by vigorous production of stump suckers, but also by root suckers, especially in the northern par ...

Betulaceae
Betulaceae, the birch family, includes six genera of deciduous nut-bearing trees and shrubs, including the birches, alders, hazels, hornbeams, hazel-hornbeam, and hop-hornbeams numbering a total of 167 species. They are mostly natives of the temperate Northern Hemisphere, with a few species reaching the Southern Hemisphere in the Andes in South America. Their typical flowers are catkins and often appear before leaves. In the past, the family was often divided into two families, Betulaceae (''Alnus'', ''Betula'') and Corylaceae (the rest). Recent treatments, including the Angiosperm Phylogeny Group, have described these two groups as subfamilies within an expanded Betulaceae: Betuloideae and Coryloideae. Betulaceae flowers are monoecious, meaning that they have both male and female flowers on the same tree. Their flowers present as catkins and are small and inconspicuous, often with reduced perianth parts. These flowers have large feathery stamen and produce a high volume of ...

Vancouveria Hexandra
''Vancouveria hexandra'', the white inside-out flower, is a perennial herb in the barberry family Berberidaceae. It is found in southwestern British Columbia, western Washington and Oregon and northwestern California and is a common understory herb in moist, shady Douglas fir forests. This plant grows high with compound leaves in triplets and is usually found in dense patches. It gets its name from the small delicate white flowers with petal-like sepals that are swept back abruptly as if in the process of turning inside out. The genus honors George Vancouver, the 18th-century explorer of the Pacific Northwest The Pacific Northwest (sometimes Cascadia, or simply abbreviated as PNW) is a geographic region in western North America bounded by its coastal waters of the Pacific Ocean to the west and, loosely, by the Rocky Mountains to the east.

Berberis Nervosa
''Mahonia nervosa'', commonly known as dwarf Oregon-grape, Cascade barberry, Cascade Oregon-grape, or dull Oregon-grape, is a flowering plant native to the northwest coast of North America from southern British Columbia south to central California, with an isolated population inland in northern Idaho. It is especially common in second growth, Douglas-fir or western redcedar forests, making use of those pools of sunlight that intermittently reach the ground. Some authors place the entire genus ''Mahonia'' within the genus ''Berberis''. The plant was collected by Lewis and Clark during their famous expedition to the West before being described for science by Frederick T. Pursh in 1813.''Fl. Amer. Sept.'' (Pursh) 219. 1814 ec. 1813 Collectors: M.Lewis, W.Clark s.n. Description It is an evergreen shrub with short vertical stems, mostly less than , while the leaves reach higher, rarely up to tall on exceptional sites. The leaves are compound and of opposite arrangement, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Achlys Californica
Achlys ( grc, Ἀχλύς "mist"), in the Hesiodic ''Shield of Heracles'', is one of the figures depicted on Heracles' shield, perhaps representing the personification of sorrow. In Homer, ''achlys'' is the mist which fogs or blinds mortal eyes (often in death). Her Roman counterpart Caligo was said to have been the mother of Chaos. In Nonnus's Dionysiaca, she seems to be a witch. Sources Homer In Homer, the word achlys (ἀχλύς, 'mist'), is frequently used to describe a mist that is "shed" upon a mortal's eyes, often while dying. For example in the ''Iliad'', the hero Sarpedon while grieviously wounded: :his spirit failed him, and down over his eyes a mist χλύςwas shed. Howbeit he revived, and the breath of the North Wind as it blew upon him made him to live again after in grievous wise he had breathed forth his spirit. While in the ''Odyssey'', Eurymachus, one of the suitors of Penelope, hit in the chest by an arrow from Odysseus: :let the sword fall from his hand ...

Berberidaceae
The Berberidaceae are a family of 18 genera of flowering plants commonly called the barberry family. This family is in the order Ranunculales. The family contains about 700 known species, of which the majority are in ''Berberis''. The species include trees, shrubs and perennial herbaceous plants. General The APG IV system of 2016 recognises the family and places it in the order Ranunculales in the clade eudicots. In some older treatments of the family, Berberidaceae only included four genera (''Berberis, Epimedium, Mahonia, Vancouveria''), with the other genera treated in separate families, Leonticaceae (''Bongardia, Caulophyllum, Gymnospermium, Leontice''), Nandinaceae (''Nandina''), and Podophyllaceae (''Achlys, Diphylleia, Dysosma, Jeffersonia, Podophyllum, Ranzania, Sinopodophyllum''). ''Mahonia'' is very closely related to ''Berberis'', and included in it by many botanists. However, recent DNA-based phylogenetic research has reinstated ''Mahonia'', though with a handfu ...

Athyrium Filix-femina
''Athyrium filix-femina'', the lady fern or common lady-fern, is a large, feathery species of fern native to temperate Asia, Europe, North Africa, Canada and the USA. It is often abundant (one of the more common ferns) in damp, shady woodland environments and is often grown for decoration. Its common names "lady fern" and "female fern" refer to how its reproductive structures ( sori) are concealed in an inconspicuous – deemed "female" – manner on the frond. Alternatively, it is said to be feminine because of its elegant and graceful appearance. Characteristics ''Athyrium filix-femina'' is now commonly split into three species, typical ''A. filix-femina'', '' A. angustum'' (narrow lady fern) and '' A. asplenioides'' (southern lady fern). ''Athyrium filix-femina'' is cespitose (the fronds arising from a central point as a clump rather than along a rhizome). The deciduous fronds are light yellow-green, long and broad. Sori appear as dots on the underside of the frond, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
