FLORA OF ICELAND elements: Carex atrata, Black Alpine-sedge

Carex atrata; The Black Alpine-sedge grows wide-spread on Iceland, but for the barren interrior regions. I have seen this species is usually found in lusher vegetations, both in grasslands and in Icelandic forests. Characteristic this species has a couple of terminal spikes> Unlike similar species the top spike is not a sigle male flower spike. The spikes are black.
The Black Alpine-sedge is a member of the sedge family (Cyperaceae). The Icelandic name of this species is Hnappstör.
