Festuca Filiformis
''Festuca filiformis'', known by the common names fine-leaf sheep fescue, fine-leaved sheep's-fescue, hair fescue, and slender fescue, is a species of Poaceae, grass. It is native to Europe, and it is widespread elsewhere as an introduced species and often a weed. References Festuca, filiformis Plants described in 1794 {{Pooideae-stub ...

Pierre André Pourret
Pierre André Pourret (1754–1818) was a French abbot and botanist who did research and teaching in France and Spain. He described and collected large amounts of plant species, especially from the Mediterranean, and amassed many species in his botanical garden and herbarium for his research. Pourret was also a pioneer user of binomial nomenclature, first developed by Carl Linnaeus. Career Pierre André Pourret was a clergyman, but started his botanical career earlier, working in the regions around his hometown, Narbonne. His given parish, however, was Saint-Jacob in Provence. He sent manuscripts of documented research to the ''Académie des sciences, inscriptions et belles-lettres de Toulouse''. During the French Revolution in 1789, Pourret was exiled to Spain. He did botanical work in Barcelona, Madrid, and ultimately the city of Ourense in Galicia.

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as forage, feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of bi ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festuca
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus '' Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640.Darbyshire, S. J. and L. E.
