ORTHOTHECIUM DIMINUTIVUM DISCOVERED AT SCOTT'S FALLS IN ALGER COUNTY, MICHIGAN

摘要

Scott's Falls is already a famous bryophyte site, with the intriguing Schis-tostega pennata (Hedw.) Web. & Mohr adorning the ceiling of the cave behind the falls and on adjacent ledges (Crum 1976). Now another interesting find―the first occurrence east of the Rockies for Orthothecium diminutivum, a relatively rare moss even in its native western distribution of Colorado, Utah, Oregon, and Washington.
