|discussion=<p>Sisyrinchium mucronatum can be a difficult species to identify, especially in the north. Herbarium specimens seem to indicate that morphologically it may approach S. septentrionale in central Canada, and narrow specimens of S. montanum in the northeast. Fresh material, however, reveals that S. septentrionale tends to have much paler flowers with no emarginate apices and much longer outer spathes, and that S. montanum usually has much wider stems, leaves, and bracts, and the outer tepals have emarginate to retuse apices. Southeastern populations of S. mucronatum tend to be more scabrous while northwestern populations have less purple in the spathes.</p>
