coastal sedge, Carex exilis

I suppose one reason I like Ives Preserve so much is that it's a great place for sedges. When I first started figuring out what grows there, I was forced to figure out sedges. Turns out they are great puzzles. Like all puzzles, you need to learn the rules and techniques. Once you do, sedges are an endless supply of medium difficulty puzzles. This one turns out to be coastal sedge, and it's a bit of a different puzzle. Mostly it hangs out in the north, in CT, DE, MA, MD, ME, MI, MN, NH, NY, RI, VT, WI, LB, NB, NF, NS, ON, PE, QC, and on SPM. But then it jumps to AL, GA, MS, and NC. An unusual range, probably involving mountains? Mackinac Co MI, 5/27/17. Sedge family, Cyperaceae.
