For a long time this very handsome species of Osmunda was 
considered peculiar to the United States and Canada, where it 
undoubtedly has its maximum. It is now found to extend it-

to Mexico, Guatemala, New Granada, and Brazil, retaining its 
ordinary character, that is, the dimorphous fronds, in the fertile 
ones wholly fertile (or, comparatively rarely, two or three of the 
lowest pair of pinne sterile); in this respect bearing the same
