Til er minni tegund Lókefli - Typha - Þessi strá eru augnayndi og er helst að finna við ferskvatns tjarnir. Þau verða 2. m á hæð með grágræn laufblöð og á efsta hluta stöngulsins á stráinu eru bústin brúnrauð fræin sem minna á mús með skott, eins og Enska nafnið gefur til kynna.

Dúnkefli er hávaxin vatnajurt og efst á stönglinum er hér um bil 20 cm langt brúnt kefli sem er mjúkt viðkomu. Og ef maður rífur það í sundur er eins og dúnn sé inni í því og af þvi dregur jurtin nafnið. Lesa meira: http://timarit.is/view_page_init.jsp?...

Also incorrectly known as Bulrush. True Bulrush is a sedge, Schoenoplectus lacustris. In the USA, Reedmace is known as 'cattails'. A single inflorescence may produce as many as 200,000 seeds! The seeds are wind dispersed. The sterile flowers in the female heads function to keep the seeds which develop from fertile flowers as dry as possible, so that they can be effectively dispersed. In wet weather the sterile flowers swell, absorbing water in the inflorescence and protecting the seeds from becoming sodden and hence too heavy for effective wind dispersal.. In dry weather, the hairs on the pedicels spread and the inflorescence 'bursts'. The fruits drift away still attached to the hairy pedicels. If they land on dry ground, the hairs remain spread so that there is the chance they may be blown away again to reach a more suitable habitat. If the fruit lands on water, the hairs remain spread for a short time, but after a few minutes, the hairs fold back. This brings the fruit into contact with the water. When wetted, the pericarp (fruit wall) springs open, releasing the seed which immediately sinks. See more: http://www.countrysideinfo.co.uk/wetl...

These plants have many common names. They may be known in British English as bulrush, or reedmace, in American English as cattail, catninetail, punks, or corn dog grass, in Australia as cumbungi or bulrush, in Canada as bulrush or cattail, and in New Zealand as raupō. Other taxa of plants may be known as bulrush, including some sedges in Scirpus and related genera. The rhizomes are edible. Evidence of preserved starch grains on grinding stones suggests they were eaten in Europe 30,000 years ago. Typha leaves are alternate and mostly basal on a simple, jointless stem that bears the flowering spikes. The plants are monoecious, with unisexual flowers that develop in dense racemes. The numerous male flowers form a narrow spike at the top of the vertical stem. Each male (staminate) flower is reduced to a pair of stamens and hairs, and withers once the pollen is shed. Large numbers of tiny female flowers form a dense, sausage-shaped spike on the stem below the male spike. In larger species this can be up to 30 centimetres long and 1 to 4 centimetres thick. The seeds are minute, 0.2 millimetres long, and attached to fine hairs. When ripe, the heads disintegrate into a cottony fluff from which the seeds disperse by wind.

A 171-hectare reserve bought by the RSPB in 1989. It is predominantly wet grassland but also has farmland, woodland, hedgerows and other habitats. Main bird interest is in winter with many species of waterfowl and over-wintering raptors. There is also passage of waders in the spring and autumn and a wide range of breeding birds including Nightingale, Lesser Whitethroat and chats. See more: https://www.birdguides.com/sites/euro...
