Gymnosperms of the United States & Canada
by Elray S. Nixon, illustrated by Bruce Lyndon Cunningham
What is a gymnosperm?
The word gymnosperm literally means “naked seed” (gymno=naked, sperm=seed). Gymnosperms have their seeds exposed unlike flowering plants, the angiosperms, which have their seeds enclosed in an ovary (i.e., fruit). The word angiosperm derives its meaning from angio=vessel, sperm=seed.
Pine trees are the most often cited example of a gymnosperm. But what about the other gymnosperms? How do we know when we see one? Do all gymnosperms have cones? These questions and many others are answered in Gymnosperms of the United States & Canada. Abundant illustrations, easy-to-follow keys, and clear descriptive text make this guide a great resource when learning about the gymnosperms in your area.
