S. calycantha of Michigan Flora.

Most often in forests of spruce, fir, and birch, of tamarack, of cedar, or even of northern hemlock-hardwoods, especially in openings or hollows, along trails, etc.; also on gravelly shores and borders of ponds and marshes.

This is our only species in the genus characterized by ciliate leaf margins without any other pubescence; it is also our only one that regularly lacks petals (a very few of the specimens from Isle Royale have petals barely equaling the sepals).
