Notes on Lophozia VI. Taxonomy and distribution of Lophozia and Schistochilopsis (Lophoziaceae) in North America north of Mexico

摘要

The North American hepatic flora includes 24 species of Lophozia distributed among five subgenera and five species of Schistochilopsis. Lophozia pacifica Bakalin is described as new to science, based on retuse leaves clearly decurrent on the dorsal side of the stem and fusiform-cylindrical perianth. Lophozia sect. Heteromorphae R. M. Schust. and L. sect. Savicziae Bakalin are synonymized with L. sect. Lophozia. Lophozia sect. Longidentatae R. M. Schust. is synonymized with Lophozia sect. Excisae R. M. Schust. New combinations are proposed: Lophozia subg. Obtusifolium (H. Buch) Bakalin comb. nov., Lophozia subg. Sudeticae (Schljakov) Bakalin comb. nov., Schistochilopsis sect. Heterogemmae (Jorg.) Bakalin comb. nov., Schistochilopsis incisa var. opacifolia (Culmann) Bakalin comb. nov.
