Arctoa (2013) 22: 35-40 LIVERWORTS OF THE ILYCH RIVER VALLEY (KOMI REPUBLIC) ПЕЧЕНОЧНИКИ РЕКИ ИЛЫЧ (РЕСПУБЛИКА КОМИ) MICHAEL V. D ULIN1 МИХАИЛ В. ДУЛИН1 Abstract An annotated list of liverworts of the Ilych River is provided. It includes 83 species and two varieties of one subspecies, of which 24 species and one variety are new to the study area. Cephaloziella elegans and Cephaloziella arctogena are first cited for the flora of the Republic of Komi. Five new sites are identified for species included in the Red Book of the Komi Republic: Arnellia fennica, Cephalozia macounii, Heterogemma laxa, Lophozia ascendens, Oleolophozia perssonii. The distribu- tion range and ecology of rare taxa, formerly known for the republic at individual points are extended. Резюме Приводится аннотированный список печеночников долины р.Илыч, включающий 83 вида, 2 разновидности и 1 подвид, из них 24 вида и 1 разновидность являются новыми для территории исследования. Cephaloziella elegans и Cephaloziella arctogena впервые указываются для флоры Республики Коми. Выявлены новые местонахождения пяти видов, включенных в Красную книгу Республики Коми: Arnellia fennica, Cephalozia macounii, Heterogemma laxa, Lophozia ascendens, Oleolophozia perssonii. Расширено представление о распространении и экологии редких таксонов, приводившихся ранее для территории Республики Коми из единичных точек.
