|discussion=<p><i>Koenigia islandica</i> is among the smallest of terrestrial flowering plants and one of few annual species in arctic and alpine floras. Some other species exhibit a similar bipolar distribution (e.g., <i>Anemone multifida</i> Poiret, Osmorhiza chilensis Hooker & Arnott, and <i>Carex macloviana</i> D’Urville).</p>
