Ebook: The Pteridophytes of Mexico

The pteridophytes of Mexico include 1008 species and 16 additional varieties or subspecies, a total of 1024 taxa in 124 genera. Keys, descriptions, distribution maps, and cited specimens are given for all species. Nearly all taxa are illustrated with line drawings. This treatment fills the gap between two other recent large floras, those for North America north of Mexico and for Mesoamerica, and spans the most diverse and latitudinally largest pteridophyte flora in the world. It weds the world’s richest dryland pteridoflora of northern Mexico and western United States with the rich wet forests of Mesoamerica, South America, and the West Indies.
