Excerpt from North American Species of Agrostis The present paper is an attempt to classify our knowledge concern ing one of our most perplexing genera of grasses. It deals chiefly with those species found north of Mexico, but includes a few notes on the Mexican species. The preparatory study naturally divided itself into two rather distinct lines - the classification of the species, or taxonomy, and the history of the Species, or nomenclature. Each line presents difficulties, a few of which are discussed below. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
