Luzula Hitchcockii
''Luzula hitchcockii'' is a species of flowering plant in the rush family known by the common names smooth woodrush and Hitchcock's wood rush. It is native to western North America from British Columbia and Alberta to Oregon to Wyoming. It is sometimes treated as a variety of '' Luzula glabrata''.''Luzula glabrata'' var. ''hitchcockii''. USDA Plants Profile. This perennial rush produces rounded, hollow stems up to 50 centimeters tall. The shiny, red-tipped leaves are a few centimeters long. The contains solitary or paired flowers with small reddish or br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leena Hämet-Ahti
Leena Hämet-Ahti (née Hämet, b. 3 January 1931, Kuusamo) is a Finnish botanist, plant taxonomist, and plant collector noted for being Associate Professor of Botany at the University of Helsinki, and later the Director of the university's Botanical Garden. She primarily studies alpine plants of Finland and similar northern hemisphere climates. Her PhD thesis, defended in 1963, was on mountain birch forests. She participated in the production of the seminal Finnish floras ''Retkeilykasvio'' (1984, 1998) and ''Suomen puu- ja pensaskasvio'' (1992). Hämet-Ahti won the Finnish Cultural Foundation prize in 1990 and the silver Kairamo medal in 2007 "in recognition of her many merits in botany, university teaching, science popularisation and fostering Finnish cultural heritage". Her book ''Maarianheinä, mesimarja ja timotei'' won a in 1987 and her ''Suomen puu- ja pensaskasvio'' was selected as in 1989. Hämet-Ahti has been a member of the Finnish Academy of Science and Lette ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subalpine
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in ...

Flora Of The Northwestern United States
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of 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 flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1971
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...
