    This is our largest and most widely spread species and probably our most common one. It is well characterized by its cylindrical, tight sheaths, which are as broad as long or sometimes a little broader or narrower than long, its persistent teeth, and very numerous, rounded ridges. It may be found on sand banks, in poor soil, in swamps and bogs; generally near water. Mr. C. K. Dodge has collected it near Port Huron, Mich., and near Sarnia, Ontario.
