Male plant a little reduced, showing antheridial receptacles. 3. Longitudinal section of antheridial receptacle magnified. 4. Female plant reduced showing the stalked receptacles which characterize this family. These receptacles vary in the family from the shape shown in this figure to almost perfectly conical and entire. 5. Section of a part of a female receptacle magnified, showing two sporogonia. The seta of one has elongated, pushing the capsule out from the outer fringe (involucre) and the inner fringe (perianth). At the base of the seta is a little collar representing the base of the broken calyptra. (From Bryologist, 4:34-35, 1901.) CONOCEPHALUM AND MARCHANTIA. C. coNicuM (L.) Dura, and M. polymorpha L. are the only two species of this family common enough to be often collected by amateurs. They are both large, 2-5 inches or more in length, grow on moist banks, and are somewhat similar in.
