LARA-CABRERA, Sabina I.; BEDOLLA-GARCIA, Brenda Y.; ZAMUDIO, Sergio  e  DOMINGUEZ-VAZQUEZ, Gabriela. Diversity of Lamiaceae in the state of Michoacán, Mexico. Act. Bot. Mex [online]. 2016, n.116, pp.107-149. ISSN 2448-7589.

Lamiaceae is one of the most diverse families in Mexico; however, no recent data on distribution and richness were available for Michoacán. Fourteen genera and 105 native or naturalized species were recorded, following a thorough review of bibliographical sources and herbarium specimens at CIMI, EBUM, ENCB, IEB and MEXU. Salvia is the most widely represented genus, followed by Stachys, Hyptis and Scutellaria. Five endemic species of Salvia were found and one more for Stachys, as well as two new records for Scutellaria. Most of the species are located in the Mexican Volcanic Arc province, in temperate environments where conifer, oak and mesophyllous forests prevail. Fewer representatives were found in the Sierra Madre del Sur province for most of the genera, except Vitex; mainly within the Balsas and Tepalcatepec river depressions. Those genera with North American Laurasian affinities were located in the conifer forests of the Mexican Volcanic Arc and the Sierra Madre del Sur, whereas Hyptis and Vitex of South American Gondwanan affinity were most frequent in the tropical dry forests of the Sierra Madre del Sur. Michoacán is among the most diverse Mexican states with respect to Lamiaceae; however, these numbers may increase following a significant collection effort for the noticeably neglected Sierra Madre del Sur region.
