Cypripedium acaule or Pink Lady's Slipper orchid, is a seasonal beauty. I usually think of them as wetland plants, but this one was growing in sandy soil on a bluff above the Pere Marquette river. Most wild orchids are protected in Michigan.
I teach economics at Kalamazoo College. My wife is also an economist. We were on sabbatical in Europe for the 2014-15 academic year. (Salamanca, Spain, followed by Oxford, UK.) We were in Uruguay for the 2006-7 academic year.
