Carex capillaris; The Hair Sedge is a rather small sedge which is common throughout Iceland, but for the barren highland deserts. It grows on rather moist soils in heathers and grasslands. It is characterized by the female spikes (the top spike is an erect mainly male-flowered spike) on slender stalks which readily droops on the developing plants. In the early flowering-stage this though is not yet very evident. It is quite similar to the Mounain Bog-sedge (Carex rariflora). The Hair Sedge can be seperated by the long pointed beaks of the utricles on the female spikes.
It is a member of the sedge family (Cyperaceae). The Icelandic name of this species is Hárleggjastör.
