Sisyrinchium mucronatum A. A. Reznicek

 Wet meadows, fields, and ± open ground; definietely a calciphile and most abundant in moist calcareous flats and open fen-like thickets near the north end of Lake Huron. Rare in dry to moist calcareous habitats inland, like gravelly riverbanks.

Ordinarily a distinctive, delicate, wiry plant with small capsules and purplish spathes; plants occasionally approach S. montanum in stature, but may be placed here by smaller capsules and slightly narrower stems and foliage. The plant is rather dark green when dry (though usually slightly glaucous); the leaves and stems in Michigan specimens apparently are entirely smooth. The spathes are often ± geniculate at the base, while in S. montanum they are normally straight.
