MOSSES AND LIVERWORTS.
G. H. GRAHAM, M.A.
THE Geological Survey of Canada has published comprehensive lists of the Bryophyta—P art VI on the Mosses, VII including the Liverworts—and these contain a good representation of Southern Ontario forms, and especially of the Lake Erie and Eastern Lake Ontario Districts. As Toronto lies between the two it probably comprises in its flora a majority of the species found in both. If this be the case the following list contains little more than a third of the mosses and liverworts growing within easy collecting distance of the city.
The author is under special obligation to Professor Coleman for the list of interglacial mosses from Scarborough and the Don.
