West Clear Creek Wilderness bisects the Mogollon Rim in Arizona, and is nested between the Colorado Plateau and Basin and Range physiographic provinces. Between 2013 and 2016, a floristic inventory vouchered 542 taxa and reviewed 428 previous collections to produce a total plant inventory of 594 taxa from 93 families and 332 genera. The most species rich families were Asteraceae, Poaceae, Fabaceae, Brassicaceae, Rosaceae, Plantaginaceae, Cyperaceae, and Polygonaceae. Carex, Erigeron, Bromus, Muhlenbergia, and Oenothera were the most represented genera. Nonnative taxa accounted for seven percent of the total flora. Stachys albens was vouchered as a new state record for Arizona. New county records include Graptopetalum rusbyi (Coconino), Pseudognaphalium pringlei (Coconino), Phaseolus pedicellatus var.grayanus (Coconino), and Quercus rugosa (Coconino and Yavapai). This study quantified and contrasted native species diversity in canyon versus non-­‐canyon floras across the Southwest. Analyses based on eighteen floras indicate that those centered about a major canyon feature show greater diversity than non-­‐canyon floras. Regression models revealed that presence of a canyon was a better predictor of similarity between floras than was the distance between them. This study documents the remarkable diversity found within canyon systems and the critical, yet varied, habitat they provide in the southwestern U.S.
