Abstract
A discussion in gymnosperms as a group is somewhat meaningless so far as discerning trends or ascertaining general principles. It is now generally recognized (1, 2) that g3niinosperms as a class probably never existed, and that gymnospermy should be regarded as a way of life rather than suggesting that the plants possessing naked seeds are somehow closely related. So before surveying the occurrence of Polyploidy in gymnosperms, it might be appropriate to indicate the kinds and degree of relationships of plants that are loosely included in the group.
