How to know the ferns

A practical field guide introduces readers to identifying, locating, and understanding common ferns, presenting clear descriptions of names, habitats, and growth habits. It defines technical terms and summarizes fern fertilization, development, and notable families, then explains how to use the book. A step-by-step guide leads into grouped species accounts that combine concise morphological descriptions with habitat notes. Pen-and-ink illustrations and photographs accompany plates that emphasize diagnostic features and typical sizes. The volume closes with indices to Latin and English names and technical terms to aid quick reference.
