The Flora of the Four Corners Region details the vascular plants that grow In the San Juan River drainage where the boundaries of four states meet. A terrain of rugged wildlands, diverse topography, and ever-changing local climates, the region possesses one of the highest rates of plant endemism in North America. Among the 2303 taxa recorded, 41 are considered to be endemic, or near endemic, to the region, and this significant genetic variation is related to the ecological diversity of the area. Plant identification guides, dichotomous keys and descriptions, line drawings, watercolor paintings, color pencil artwork, and photographs make Flora of the Four Corners Region the first for this unique area.
