I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
Silene flos-cuculi, commonly known as the ragged robin, is a perennial herbaceous plant in the family Caryophyllaceae. Native to Europe and Asia, it is found along roads and in wet meadows and pastures, and has also become naturalized in parts of North America. It forms a rosette of low growing foliage with numerous stems that are 30 to 90 centimetres (12 to 36 inches) tall. The stems rise above the foliage and branch near the top of the stem, the stems having barbed hairs which point downward and make the plant rough to the touch. The middle and upper leaves are linear-lanceolate with pointed apexes. Butterflies and long-tongued bees feed on the flowers' nectar. In addition to these pollinators, the flowers are visited by many other types of insects, and can be characterized by a generalized pollination syndrome. This S. flos-cuculi flower was photographed in Niitvälja, Estonia. This picture was focus-stacked from 27 separate images.Photograph credit: Ivar Leidus
