“…The vast richness and uniqueness of the Sierra de Xilitla has attracted the attention of various collectors that have conducted sporadic botanical explorations in the area. As a result, in the last 57 years, 17 plant species have been described from this area (McVaugh 1963, Lundell 1964, Matuda 1966, Landry & Wilson, 1979, Hunziker 1980, Rollins 1993, Rzedowski, 1994, Rzedowski & Guridi-Gómez, 1998, Zamudio 2001, Pérez-Calix & Patiño-Siciliano 2009, Carrillo-Reyes et al 2010, Galván & Zamudio, 2013, Bedolla-García & Zamudio 2015, 2017, Vázquez-García et al 2015Zamudio et al 2018), which highlight the need to conduct exhaustive systematic botanical explorations in the region. In particular, for the genus Salvia Linnaeus (1753: 23) the recent botanical explorations conducted in Sierra de Xilitla have led to the description of two new species: S. carranzae Zamudio & Bedolla (2015: 36), and S. guevarae Bedolla & Zamudio (2017: 6).…”
