CORNEJO-TENORIO, Guadalupe  and  IBARRA-MANRIQUEZ, Guillermo. Diversity and distribution of the genus Salvia (Lamiaceae) in Michoacan, Mexico. Rev. Mex. Biodiv. [online]. 2011, vol.82, n.4, pp.1279-1296. ISSN 2007-8706.

This paper presents the richness and distribution by municipality of Salvia species in the state of Michoacán, floristic and ecological data are included. Based on herbarium specimens deposited in CIMI, EBUM, ENCB, F, IEB, INIF, MEXU, and MO, as well as collecting trips, 64 native species of Salvia were recognized in the study area. Endemic species to Mexico and Michoacán reached 67.2% and 6.2%, respectively. Salvia iodantha Fernald and S. mexicana L. were species with most herbarium specimens (140 and 134, respectively). The vegetation types with most species (40) were Pinus-Quercus and Quercus forests. The highest number of species occurred between 1 500 and 3 000 m. The municipality with the most Salvia species recorded was Morelia (34 species). Perennial herbs and shrubs were the most common growth forms (86%). Blue and/or purple flowers are displayed by 76.5% of species. Flowering occurs year-round, with a peak in October. We suggest that in the near future increases floristic exploration of genus Salvia in Michoacán, especially in their protected areas and in the Sierra Madre del Sur.
