Manual of Grasses for North America
Considerable interest has been expressed in a compact treatment of the grasses of North America. The new manual is our response. It includes all the illustrations, plus a few more, that are found in the two FNA grass volumes, but at a reduced size. Similarly, it includes updated version of all the maps.
The saving in space comes from eliminating the citations and species descriptions, using abbreviations in the descriptions of the other taxa, creating a single index, and in adopting a space conserving design. The ecological notes have been retained, with some modification.
The taxonomic treatment in the Manual differs in few places from that in the FNA grass volumes. Both Hopia and Zuloagaea are recognized, as are the three infraspecific taxa of Phragmites. In addition, Finots treatment of Trisetum has been adopted, with some modifications. Additional illustrations have been prepared to reflect these changes and to accommodate the additional taxa of Sporobolus, Eragrostis, and Rytidosperma that have been found in the U.S. since publication of FNA 24 and 25.
