This tabic shows the four hundred and ninety-three species of Eastern North America, 

 divided into eighty-nine genera, and distributed thus : one hundred and fifty-two species, 

 or thirty and one-half per cent, belong exclusively to Eastern North America ; three 

 hundred and forty-one species or sixty-nine per cent, are common to Eastern North 

 America and Europe, and only forty-two species or eight and one-half per cent, belong 

 to Eastern North America, Europe, and Western North America. But to give a satis- 

 factory view of the distribution of our North American mosses, this table must be completed 

 by a similar one of the Californian species.
