Drepanocladus polygamus looks rather intermediate between Drepanocladus aduncus and Campylium chrysophyllum. Like Drepanocladus aduncus, it has inflated alar cells. Like Campylium chrysophyllum, the leaves can spreading or channeled. The laminar cells are longer as in D. aduncus. The leaves are not usually falcate secund in D. polygamus, although straight leaved specimens of D. aduncus do occur.
Many thanks to the J.M. Holzinger Moss Herbarium of the University of Minnesota for loaning us this specimen which was collected by P.C. Standley and determined by A.J. Grout.
