Sisyrinchium is a genus that can be challenging. Different references treat the genus very differently. Some exclude S. strictum, and would definitely call this S. angustifolium, even though its stem width is at the lower limit of the species. But the stems are also at the widest limit for S. strictum in other treatments, and the spathe and bract below the flower are close to the same length. Could this be the rare S. strictum, two counties east of its known range? We will never be sure because some photographer didn't get a specimen and probably can't find his way back. So other features remain unknown. Either way we get to see a blue-eyed-grass. S. strictum occurs in MI and WI. S. angustifolium is in AL, AR, CT, DE, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN< MO, MS, NC, NH, NJ, NY, OH, OK, PA, RI, SC, TN, TX, VA, VT, WI, WV, LB, NS, ON, and QC. Wayne Co MI, 7/3/20.
