New or Otherwise Interesting Mosses from Alberta

Abstract

Twenty-eight taxa of mosses are added to the 530 previously known taxa of bryophytes from Alberta. A recent compilation of the bryophyte taxa reported from Alberta (Bird, 1966), following the up-to-date nomenclature of Crum, Steere and Anderson (1965), enumerated 530 taxa. The present account adds 28 taxa and presents new data for five previously reported species. Voucher specimens have been deposited at UAc and CAN. Buxbaumia indusiata Brid.
