The definitive reference book on ferns of Canada. Scientifically oriented, it of course includes ferns of areas outside of Ontario. Inclusion of western species may cause confusion if you're trying to use this book for fern identification. It may be out of print. 430 pages.
An excellent book, the definitive reference for Canada, but not for beginners.

NOTE: Although this book is free, I found it very difficult to get a copy. It has been out of print for some time, but now (2006) it is available again from
PubliCentrale in Canada. However, if you want to have it shipped outside Canada, they will request you to pay about $20 shipping costs, but without any other means of paying tthis than exceedingly expensive international bank transfers, so you'll end up paying some $50 for your free copy, none of which is beneficial to the publisher to continue this wonderful service.
I found it the best way to obtain this book is to have someone living in Canada to order it and then have it shipped to you.
