Plant of the Day (May 19th, 2011) - Carex elongata L.

Carex elongata L. is the second species of the Genus Carex, which you can find in the wetland area at Lake Unterbach in Düsseldorf, Western Gemany. In Germany, we called it the “Langjährige Segge” oder “Walzen-Segge”. Unfortunately I haven't found an English translation, but the Latin name means something like “Stretched Sedge”.
