Ferns and Fern Allies of Canada, first published in 1989, is a comprehensive, illustrated guide for identifying all the species of ferns and fern allies known to occur in Canada. Each species is described, with information on its appearance, diagnostic features, habitat, and range; 159 maps illustrate known distributions across Canada. Keys are provided to each genus and species. An extensive glossary, list of references and index are also included. This new reprint edition includes all the original text in a slightly smaller field guide format and illustrations have been enlarged for improved usefulness. Although slightly dated in terms of family assignments of some species, the overall nomenclature for the book's genera and species remains very similar to that in popular usage today, making Ferns and Fern Allies of Canada an excellent reference and field guide for anyone studying ferns in North America.
