sessilefruit arrowhead, Sagittaria rigida

Yesterday's Michigan Botany Club outing seemed to be a success. It certainly was for me, with three new plant images. Arrowheads grow in shallow water along streams and lakes. They're very variable. I had to bring some of this one home and consult a manual. Most arrowhead species have leaves with lobes at the base, but sometimes not. This one, and a few others lack lobes, but sometimes will have them. It almost seems like they do this just to make things more fun. These particular flowers were ragged late season remainders, after an early morning rain. But I guess it made the image a little different. and hopefully, more interesting.
This species grows in AR, CA, CT, DE, IA, IL, IN, KS, KY(E), MA, MD(E), ME(T), MI, MN, MO, NE, NH, NJ, NY, OH(P), PA, RI, TN(S), VA, VT, WA, WI, WV, MB, ON, PE, QC, and SK. Watkins Lake State Park, Jackson Co MI, 8/19/17.
