Guide to Eastern Ferns by Edgar T. Wherry

Hardcover. Condition: Very Good. 1942. The Science Press. Second Edition. Illustrated.

This guide has been prepared to fill a need for an aid in the identification of the ferns and fernallies of the region from Pennsylvania and New Jersey to Virginia, of convenient size for field use, and, though non-technical, free from errors and misidentifications such as occur in several current fern books. The data as to each species are presented under five headings: History; Features, especially those not brought out by the drawings; Habitat, ascertained by extensive field work; Range, as known to date; Remarks, comprising methods of distinguishing similar species, and corrections of certain errors often made.
