Carex brunnescens; The Brownish Sedge is a rather small sedge that resembles the silvery/whitish sedge (C. curta). It is smaller, especially the spikes are a lot smaller. In my experience the spikes are also more brown than those of C. curta which tend to be lighter and more yellow. Also the Browwnish Sedge is found on rather dry soils where C. curta is found on (very) wet soils. It is a rare sedge on Iceland. It is most common in the south-western fjord region and in the north. Elsewhere only in a few localities.
It is a member of the sedge family (Cyperaceae). The Icelandic name of this species is Línstör.
