  • genera
  • 1500 genera, 23000 species: worldwide, many habitats. (berkeley.edu)
  • Only three genera in Cardueae are represented by native species in the New World, and of these Cirsium is by far the most widely distributed and diverse. (efloras.org)
  • This presentation is so that the plants can be sorted into the various taxonomic genera, families and classes based on that species' unique physical characteristic[s] and to help managers find more information on that particular plant. (gov.ab.ca)
  • native
  • They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). (wikipedia.org)
  • I have seen no documentation of hybridization between native American Cirsium species and introduced Eurasian taxa. (efloras.org)
  • Some of these species are exotics (not native to Montana) and some species have been designated as Species of Concern. (wikipedia.org)
  • The procedure involved the introduction of native prairie plant species by hand seeding new plots progressively across the field ( click for map ) over a period of 17 years ( see table for details ). (illinois.edu)
  • add link to new map] A 2012 survey [add link to plant list identified about 158 native species and 45 aliens prersent on the site. (illinois.edu)
  • However, the principle one is the invasion by the many alien plant species with which the native prairie did not have to contend. (illinois.edu)
  • There are more than 150 native plant species that can be found in this prairie land. (nirmi.org)
  • Alberta rangelands consist of native and introduced plant species that exist in plant communities. (gov.ab.ca)
  • A physiognomic analysis reveals that the native species consist of 42 woody species, 65 herbaceous vines or forbs, 27 graminoids, and two ferns. (thefreelibrary.com)
  • For native species only, the FQI = 25.0 and the mean Coefficient of Conservatism (mean C) is 2.2. (thefreelibrary.com)
  • The high percentage of non-native species is discussed from the standpoint of secondary succession at the site since the early 1980s. (thefreelibrary.com)
  • aster
  • Although some prairie species were present, it gradually evolved into an old field dominated by cool season alien grasses and weedy forbs such as Daucus carota (wild carrot) and Aster pilosus (hairy aster). (illinois.edu)
  • Plants
  • Species of flowering plants belonging to the daisy family. (usf.edu)
  • Introduced species of plants may be a threat, including Bromus inermis (smooth brome) and Melilotus officinalis (yellow sweet clover). (wikipedia.org)
  • These species hybridize, and plants with intermediate characteristics may occur where their ranges overlap. (ca.gov)
  • Relationships among the North American species are apparently complex, and molecular studies have only begun to provide an outline of phylogeny for these plants. (efloras.org)
  • Specific to the plant species found in a particular area at any point in time, plant communities group various population sizes of plants occurring together on the landscape. (gov.ab.ca)
  • In the " Definitions " section below, Plant type groups various species with similar physical characteristics to define them as grasses, grass-like plants, forbs, shrubs or trees. (gov.ab.ca)
  • Biennial plants - require two years to complete life cycle. (gov.ab.ca)
  • No species occur on the IDNR list of endangered, threatened, or rare plants. (thefreelibrary.com)
  • field
  • In other cases hybridization has been invoked without much evidence as an explanation for Cirsium variants encountered in herbaria or in the field. (efloras.org)
  • Greek
  • In this factsheet, each range plant species is shown under two names: a common (English) name and a scientific (Latin or Greek) name. (gov.ab.ca)
  • prairie
  • Fortunately a healthy prairie will displace most of these, but maybe not totally and in the cases of a few species, not at all. (illinois.edu)
  • The intent of this project is to establish a mix of prairie species that probably grew in the region in pre-settlement times. (illinois.edu)
  • In 1974 a systematic effort was started to introduce prairie species. (illinois.edu)
  • wild
  • Species novel to our study were: great willowherb, common stork's-bill Erodium cicutarium , wild strawberry, hedge bedstraw Galium mollugo, timothy Phleum pratense, groundsel Senecio vulgaris and pink water-speedwell Veronica catenata. (thefreedictionary.com)
  • although
  • Although there has been a remarkable evolutionary and morphologic diversification in North American Cirsium , it has not been accompanied by very much divergence in the base sequences of genes commonly used to elucidate phylogenetic relationships. (efloras.org)
