Books

 * Good field guide for the northeastern US, with dichotomous keys. Species descriptions vary in length; rarer taxa tend to get a rather brief description.
 * The authoritative manual for plant identification in the northeastern US.
 * Species descriptions and cultivation for a number of North American ferns.
 * fill in title and author parameters for the appropriate genus or species sub-article
 * Comprehensive floristic account of pteridophyte taxa in North America (excluding Mexico).
 * A manual on the cultivation of ferns in North America. Includes short species-specific accounts and growing conditions for a large number of species, both native and foreign species cultivated in the US and Canada.
 * Keys and guide to, description of, and brief cultivation information for all ferns and fern allies of North America (exclusive of Mexico). Taxonomy obviously somewhat dated (pre-molecular systematics).
 * Regional flora. Some taxonomy questionable. Good for information on certain hybrids and forms and varieties of the ferns described.
