Genus |
Chamerion (fireweed) | ||
Species in the genus Chamerion were formerly placed it in the genus Epilobium. They had previously been placed in the genus Chamaenerion, and some authors continued to use that genus. Based on a monograph published in 2007, Chamaenerion was separated from Epilobium under the new shortened name Chamerion. Some sources, including Germplasm Resources Information Network (GRIN), continue to use the original spelling Chamaenerion. |

About
Published on Sep 6, 2013 Willowherb - Epilobium angustifolium - Chamerion angustifolium - Rosebay Willowherb - Fireweed - Dúnurt - Sigurskúfur Sigurskúfur (fræðiheiti: Epilobium angustifolium) er fjölær jurt af eyrarrósarætt. Hann tilheyrir dúnurtum og getur orðið allt að 70 cm á hæð. Sigurskúfur ber rauð blóm og er algengur um allt norðurhvel jarðar. Blómin eru mörg í klasa upp eftir plöntunni. Þau eru um 2 cm í þvermál. Krónublöðin eru rauð en bikarblöðin dökkrauð. Í hverju blómi er 8 fræflar. Frævan er löng og hærð. Blöðin standa gagnstætt á stilknum. Þau eru 4 til 12 cm á lengd og 1 til 2 cm á breidd. Þau eru lensulaga, heilrennd eða með litlar tennur og hárlaus. Sigurskúfur er áburðarfrekur og vex því gjarnan í kringum bæi - oft í þéttum breiðum. Í skóglendi og klettum vex hann villtur - blómstrar seint. Í gras- eða mólendi er hann stundum dvergvaxinn og blómstrar ekki vegna næringarskorts. Þá myndar hann 10 til 20 cm langa blaðsprota. : http://is.wikipedia.org/wiki/Sigursk%C3%BAfur Rosebay Willowherb is an adaptable friend. Most parts of the plant are edible, medicinal and have other fantastic properties. See more: http://awalkaroundbritain.com/knowledge/plant-and-tree/plant-profiles/rosebay-willowherb/ This herb is often abundant in wet calcareous to slightly acidic soils in open fields, pastures, and particularly burned-over lands; the name Fireweed derives from the species' abundance as a coloniser on burnt sites after forest fires. Its tendency to quickly colonize open areas with little competition, such as sites of forest fires and forest clearings, makes it a clear example of a pioneer species. The reddish-brown linear seed capsule splits from the apex. It bears many minute brown seeds, about 300 to 400 per capsule and 80,000 per plant. : http://en.wikipedia.org/wiki/Epilobium_angustifolium Willowherbs are typically very quick to carpet large swathes of ground and may become key or dominant species of local ecosystems. In and around the United Kingdom, for example, rosebay willowherb (E. angustifolium) is widely found in mesotrophic grassland dominated by false oat-grass (Arrhenatherum elatius), cock's-foot (Dactylis glomerata), and red fescue (Festuca rubra), while great willowherb (Epilobium hirsutum) is found in mesotrophic grassland with stinging nettle (Urtica dioica). These two willowherb species are also seen to dominate open habitat early in ecological succession, to the virtual exclusion of other plant life. Broad-leaved willowherb (Epilobium montanum) is found characteristically, though not abundantly, in the mesotrophic grasslands with meadowsweet (Filipendula ulmaria) and sometimes the uncommon Greek valerian (Polemonium caeruleum), which are peculiar to the Pennines. Most willowherbs will not tolerate shade trees and thus are limited to more recently disturbed patches, yielding to other plants over time. Consequently, though the genus contains many pioneer plants, rather few of them are invasive weeds of major importance. : http://en.wikipedia.org/wiki/Chamerion Rosebay willowherb is tolerant of acid and alkaline soils but does not grow in soils with poor mineral nutrition. Rosebay willowherb tolerates shade and a broad range of climatic conditions. It is suspected by some botanists that the sudden spread of rosebay willowherb was due to the introduction of the North American form that has 72 chromosomes while the native form has 36. Considerable intraspecific variation has been observed in rosebay willowherb in North America where it is eaten by deer and range cattle. It was also used as a food plant by the native indians. The nectar is important for hive bees in certain localities. Seeds remain viable for 18 months but do not form a persistent seedbank. Seeds lose viability after 18 months dry storage at room temperature but persist for more than 2 years stored dry at 5°C. : http://www.gardenorganic.org.uk/organicweeds/weed_information/weed.php?id=116 Á íslandi finnst fylgjandi jurtir af dúnurtum: Sigurskúfur er tiltölulega ný r landnemi á Íslandi : http://nature.is/frettir/1764/ Unfortunately handheld, with such a macro and a minuscule depth of field the video is shaky and not always on focus. |
