Studies of surface-water pH and bryophyta assemblages in 440 plots from five peatland regions across northern North America show a very distinct, two-fold division into fens with pH of 6.76-7.00, in which Amblystegiaceae are prominent, and bogs with pH of 4.01-4.25, in which Sphagnaceae are dominant. The relevance of the data to past and current views on peatland classification is explored.
