How to Know the Ferns

The book introduces the vascular cryptogams—ferns, horsetails and club mosses—explaining their structure, life cycles, and distinguishing features. It reviews fossil evidence and past relatives such as seed-bearing fern-like groups and Bennettiteæ to outline evolutionary connections. Subsequent chapters provide concise descriptions and illustrated identifications of many fern groups, highlighting frond forms, sori and reproductive structures. Practical guidance is offered on field collecting, preservation, and the culture and cultivation of ferns for amateur naturalists and gardeners.
