I t is with much reluctance that we dissent from the views
of Bruch and Schimper concerning this moss, which we assume
to be identical with their Phascum pachycarpon, while it
exactly corresponds with original specimens of Dr. Greville s
P. crassinervium, and with his admirable figure and description,
