The moss flora of the Douglas Lake region of northern Michigan has been thoroughly studied during the past 50 years. From the time the first bryology course was taught at UMBS by George E. Nichols in 1920 through to the present course taught by Howard A. Crum, a large collection of the mosses occurring in this region has been made. A detailed list of this flora has been published by Crum (1964; 1965), with additions by Miller and Crum (1966) and Crum and Miller (1967). No publications are known which deal with the chromosome numbers of mosses of the area. The present paper reports counts on six species collected in the Douglas Lake region and adjacent counties.
