Containing the latest taxonomic knowledge, these works bring readers up to date on the flora of Colorado. The wide variations in altitude, due to the range of mountains, basins, and plains within the botanical region, provide habitats for an equally significant variation in species. Distinguished in their scientific field, the authors have spent decades examining the flora and and understanding the differences between species. This work reflects an intimacy with the subject as well as with the history of field botany and its future. Supplementary materials include drawings of plants, suggested readings, an index to common and scientific names, and references.
