Résumé
Rio Mayo Valley in Sonora, Mexico, is an area highly convenient for biological studies. A Sub-tropical zone between the Lower Sonoran and Upper Sonoran life zones is an important feature of this area » Plant collections in the valley have been made by many explorers. The most faithful record is the Gentry collection representing about 3200 specimens. His publication, Rio Mayo Plants, also, is the first one regarding geography, vegetation, plant census, succession and plant uses. This study was undertaken to provide a means for the identification of the species cited by Gentry in his work through the Rio Mayo Basin. Keys are given to separate all taxa : 131 families, 532 genera, 1245 species, and 94 subspecific categories. An appendix is included to bring up-to-date the nomenclature for the taxa.

Mots clés : Gentry, Howard Scott. — Río Mayo plants.. ; Botany — Mexico — Mayo River Valley. ; Plants — Classification. ; Plants — Identification.
