Novelties on the distribution of Lepechinia flammea (Lamiaceae), rediscovery of L. glomerata in Jalisco, Mexico, and their phylogenetic position within Lepechinia

Abstract

The recently described Lepechinia flammea was originally known only from the Sierra Madre del Sur in Guerrero, Mexico. However, a new population of this species was uncovered in Jalisco during recent botanical explorations. Additionally, it was more recently described in Oaxaca as L. oaxacana , a name that in this work is synonymized with L. flammea . Meanwhile, L. glomerata , the most morphologically similar species to L. flammea , was rediscovered in Jalisco. Morphological notes on L. flammea , an extended description of L. glomerata , and photographs and distribution maps for the two species are provided. We also explore the relationships of these two species within Lepechinia , and show they are closely related to the more broadly distributed L. nelsonii .
