A quarterly devoted to ferns.

"The Bryologist...devoted to the study of North American mosses," included in v. 6-7.

This detailed account of ferns and fern-allies was first published in 1967 as the first volume in the series The Illustrated Flora of Illinois. Eminent botanist Robert H. Mohlenbrock has now revised Ferns to include twenty-five additional taxa of ferns that have since been discovered in Illinois. In addition, numerous nomenclatural changes have occurred for plants already known in the state.

Vols. 4- include Annual report of the American Fern Society, 1913-
