|discussion=<p><i>Carex microglochin </i>subsp.<i> microglochin</i> is usually rare to occasional in subarctic North America and scattered in the cordilleran region. It can be locally abundant (e.g., Brooks Range, Alaska) or even dominant (e.g., western Newfoundland) despite its very spotty geographic range. It was reported from Montana by W. E. Booth (1950) and F. J. Hermann (1970); no verifying specimens have been found. Many authors, including cyperologists (e.g., E. R. Guaglianone 1996), have agreed that the populations found in Argentina, Chile, and the Falkland Islands constitute a vicariant here treated as <i>C. microglochin</i> subsp. fuegina Kükenthal [C. oligantha W. Boott, not Steudel; <i>C. microglochin</i> var. oligantha Kükenthal], differing from <i></i>subsp.<i> microglochin</i> primarily in having fewer flowers per spike and slightly longer perigynia with longer stipes. H. Roivainen (1954) asserted that both taxa (as <i>C. microglochin</i> and C. oligantha) occur in Tierra del Fuego.</p><!--
--><p><i>Carex microglochin </i>subsp.<i> microglochin</i> is an inconspicuous but interesting little plant, distinctive in having a well-developed rachilla very similar in appearance to the exserted style of <i>C. pauciflora</i>. The long-pointed perigynia, which mature quickly and detach easily, are probably dispersed by animals (M. L. Fernald 1926; D. B. O. Savile 1972).</p>
