Abstract

Ferns have been objects of interest to botanists and cultivators; they have therefore been studied more than many of the flowering plants. Their simple structure and the apparently well-defined limitation of species has rendered them easier for purposes of study than many of the groups of Phaenogams. The purpose of this paper is to make a small contribution toward our knowledge concerning the spore characters of the different genera and species of North American ferns.
