DOWNLOAD EBOOKThis second volume of the magnificent compendium exhaustively describes and classifys the ferns, fern allies, and gymnosperms of North America. Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.
