内容简介：
Missouri's diverse landscapes, geology, and climate have endowed the state with a rich and varied grass flora. From tallgrass prairies to forested Ozarks to Mississippi lowlands, the state boasts an array of grasses that can be classified into six subfamilies of the Poaceae, eighteen tribes, and eighty-seven genera.Significant changes have been made in grass classification since the first edition of The Grasses of Missouri was published in 1961, resulting in an increased emphasis on phyletic criteria. Recognizing the recent advances in classification and changes in nomenclature, this newly revised edition serves as a compilation of the native and naturalized species and subspecific taxa found in Missouri.Covering more than 275 species and subspecific entities, The Grasses of Missouri is an indispensable research tool for identifying grasses, complete with working keys, descriptions, and line drawings.
