Abstract
The seven species ofGeocalycaceae (Hepaticae) in North America west of the hundredth meridian are discussed, keyed, and provided with distribution maps. Chiloscyphus polyanthus is reported new to Arizona and Saskatchewan, Geocalyx graveolens new to Colorado, Northwest Territories, and Saskatchewan, Lophocolea bidentata new to Northwest Territories, L. heterophylla new to Alaska and Arizona, and L. minor new to Arizona. The family Geocalycaceae was established by Klinggriiff (1858). It is characterized by dioicous, autoicous, or paroicous gametangia; lateral and ventral intercalary or terminal branching; succu- bous or obliquely inserted leaves; bilobed under- leaves; rhizoids restricted to the base of underleaves or scattered over the ventral surface of stem; lateral (Lophocoleoideae) or ventral (Geocalycoideae) fer- tile branches; slenderly spicate androecia; large, re- duced, or vestigial female bracts; perianth reduced or absent, or with a rhizoidal perigynium (Geoca- lycoideae), or wide mouthed (Lophocoleoideae); and ovoid to cylindric capsule with 2-5 layered walls (Engel 1982; Fulford 1976; Schuster 1980; Smith
