|discussion=<p><i>Sisyrinchium septentrionale</i> is widespread but apparently not common in western Canada. In central Canada it intergrades with <i>S. mucronatum</i>, to which it appears closely related (see discussion, p. 367). It is confused also with <i>S. montanum</i> but can be distinguished by its very slender, very long outer spathe and nongibbous inner spathe. Fresh material will show lighter blue flowers and outer tepals with rounded apices.</p>
