Wildlife Ecology and Management. Field guide to Intermountain sedges. US Department of Agriculture, Forest Service, Rocky Mountain Research Station. Ogden, UT. 282 p. Each species is described on one page and illustrated on the opposite page.
Descriptions contain synonymy, and morphological, habitat and distribution information.
Illustrations combine line drawings with colour macrophotographs. The colour photographs show details of the inflorescence and a set of scales, perigynia and achenes. The photographs were taken by the senior author and they are excellent. The book has an extensive terminology section that is fully illustrated. It also has dichotomous keys to all 114 species, plus a few more uncommon species that are not treated in the description section.
