Including S. hastile of Michigan Flora.

Dry often sandy open fields, railroad embankments, oak-hickory forests; grassy, sometimes moist banks, shores, and pastures, even marshy ground. The Keweenaw Co. record mapped in Michigan Flora, based on an 1886 collection by O. A. Farwell, is so far out of range as to be suspect and is not mapped here.

Sisyrinchium hastile E. P. Bicknell is placed here by Cholewa & Henderson (2002). It is known only from the type (O. A. Farwell 867 in 1896, NY, BLH, GH, Belle Isle, Wayne Co.), which lacks mature flowers or fruit. The specimens have the stems slender, wiry, terete or compressed and somewhat 2-edged, but not winged (except at base); inner spathe bracts 2–3 cm long; and anthers over 2.5 mm long. Other specimens of S. albidum from Michigan are quite different and have the stems flattened and winged, inner spathe bracts usually shorter, and anthers up to 2.5 mm long. Possibly, S. hastile is better referred to S. capillare E. P. Bicknell, in which case it presumably was a short-lived waif.
