• Resumen

  • During botanical explorations in the highlands of NW Mexico, two new Salvia L. species were discovered in the state of Chihuahua: S. reginae J. G. González & J. H. Vega and S. spellenbergii J. G. González. The first one is morphologically similar to S. concolor Lamb. ex Benth., from which it differs by having smaller floral bracts, a longer upper corolla lip, stamens parallel to the dorsal corolla line, longer filament and connective, the latter ornate with an antrorse tiny acute tooth, longer thecae, longer and exserted styles, and bigger mericarps. Salvia spellenbergii resembles S. fruticulosa Benth., S. goldmanii Fernald and S. pruinosa Fernald; however, it can be distinguished from these because of its shorter petioles, smaller leaf blades, usually fewer floral nodes, fewer flowers per floral node, and regularly shorter calyces. Both species are described and illustrated. Tables with morphological comparisons, illustrations, conservation assessment, and a distribution map are also presented.
