Since the spring of 1942 numerous collections of bryophytes in the vicinity of Cedar Rapids have added several interesting and rare species to the known flora of Linn County. Most of these species are rather infrequent in the remainder of the state. From the vantage point gained with but a few years of collecting it can be said that forests and swamps on Lindley fine sand and fine sandy loam seem to be the most favorable bryophyte habitats at this time. Prairie bogs and the moist, rock-strewn, forested ravines at the Palisades State Park are also excellent collecting areas. Perhaps these habitats are so productive of interesting species because they are of little economic use and are consequently relatively undisturbed. The prairie bog south of Coggon was visited in the company of Dr. Conard of Grinnell College for the purpose of collecting Atrichum crispum. Several years ago Dr. Conard made the only Iowa collection at this station. This species seems to be increasing in abundance, which increase may be due to the greater moisture of the last few years. In this paper eleven mosses and five liverworts are reported as new to Linn County. One moss, Helodium Blancowii, is new to Iowa.
