This systematic treatment will help students, naturalists, botanists, ecologists, agronomists, range scientists, and other interested readers identify and learn about this unique and economically important plant family. The book describes over 300 native, introduced, naturalised, and adventive species. Comprehensive coverage, useful keys, and detailed species descriptions in Grasses of Colorado will make this volume the standard reference for years to come. Robert B Shaw provides overviews of Colorado's physiography and ecoregions and introduces the grass plant in plain, enjoyable text. He includes a checklist of Colorado grasses, a bibliography, and a glossary of terms that may be unfamiliar to non-specialists.
