Paspalum comprises one of the most important grass genera for animal fodder, not only because of the number of species but also because of its economic importance as one of the main components of the grasslands and prairies of the Americas.
Presented here is the study of the 129 species found in austral South America. This figure represents approximately a third of the recognized species of the genus, and many of them are endemic to the region.
Building on the pioneering work of Agnes Chase, who established the majority of the informal taxonomic groups that are accepted here, this book is a landmark in the investigation of these South American members of the genus, discussing infrageneric and species relationships. Information is provided on the history of the genus, chromosome numbers, general characteristics of foliar anatomy, and economic importance, and an infrageneric classification of the species occurring in austral South America is given. In addition, a key to the identification of all 129 species, detailed descriptions, and line drawings of the different taxa are provided.
