“…Lepechinia tiene una sinopsis (Epling 1948), un estudio sistemático contemporáneo (Hart 1983) y una serie de publicaciones que han fundamentado su estatus filogenético y que han ayudado a esclarecer su circunscripción (Drew & Sytsma 2011, Drew et al 2014. Dentro de la última década, se han descrito tres especies mexicanas (Martínez-Gordillo & Lozada-Pé-rez 2009, Henrickson et al 2011, Turner 2013c) y se han aportado notas sobre la distribución y filogenia de algunas especies en particular (González-Gallegos et al 2015).…”

ResumenAntecedentes: Lamiaceae es una de las familias con mayor riqueza de especies en México. Sin embargo, aún se carece de un estudio detallado sobre su diversidad en el país y de una revisión taxonómica global y actualizada. Como resultado, el aprovechamiento y conservación de los integrantes de esta familia es limitado. Preguntas: ¿Qué avances se han logrado en el estudio y entendimiento de la riqueza, endemismo y distribución de las Lamiaceae mexicanas? ¿Qué estrategias deben ejecutarse para consolidar el conocimiento de la familia en el país? Taxon: Lamiaceae Sitio de estudio: México Métodos: Se hizo una revisión exhaustiva de las Lamiaceae mexicanas en la literatura, bases de datos y herbarios. Se sintetizó el estado de su conocimiento. Se aplicaron análisis cuantitativos para evaluar su riqueza, endemismo y distribución geográfica. Resultados: México cuenta con 33 géneros y 598 especies, de las cuales el 66.2 % son endémicas. El género más diverso es Salvia, con 306 especies. El estado más diverso es Oaxaca, mientras que Jalisco alberga el mayor número de especies endémicas. Conclusiones: En México, Lamiaceae es la octava familia más diversa y el número de sus especies representa el 5.5 % de la familia a nivel mundial, por lo que el país puede considerarse uno de los centros de diversificación más importante. Debido a lo anterior, y al endemismo elevado que presenta, México es crucial para la conservación in situ de la familia. Si bien se ha logrado un avance considerable de su conocimiento y en la actualidad hay un repunte en su estudio, es necesario diversificar los campos de investigación. Palabras clave: distribución geográfica, endemismo, Lamiaceae mexicanas, riqueza florística. AbstractBackground: Lamiaceae is one of the most species-rich families in Mexico. However, a detailed treatment on its diversity and an updated comprehensive taxonomic review for the country are still lacking. As a result, the use and conservation of the members of Lamiaceae is limited. Questions: Which advances have been achieved on the study and understanding of the Mexican Lamiaceae in terms of richness, endemism and distribution? Which strategies should be applied to enhance the knowledge of Lamiaceae in Mexico? Taxon: Lamiaceae Study site: Mexico Methods: A thorough review of Mexican Lamiaceae in the literature, databases and herbaria was conducted. The state of knowledge of the family was summarized. Quantitative analyses were performed to assess its richness, endemism and geographical distribution. Results: Mexico embraces 33 genera and 598 species of Lamiaceae, with an endemism proportion of 66.2 %. The most diverse genus is Salvia, with 306 species. Oaxaca is the state encompassing the highest richness, whereas Jalisco harbors the highest amount of endemic species. Conclusions: In Mexico Lamiaceae is the eighth most species-rich family, with a number of species equivalent to 5.5 % of all Lamiaceae worldwide; hence the country is one of the most relevant diversification centers for the family. The high species richne...

“…Subtribe Salviinae possesses mainly bireticulate pollen except for Lepechinia and Chaunostoma, which have perforate pollen. The perforate exines of Lepechinia and Chaunostoma of Salviinae support that these genera are sister to all other genera within Salviinae (Epling 1948;Moon et al 2008a). According to molecular topologies, Salvia is not a monophyletic group (Walker et al 2004;Walker and Sytsma 2007) and pollen characters provide further evidence for this finding (Moon et al 2008a).…”

The pollen morphology of subtribe Menthinae sensu Harley et al. [In: The families and genera of vascular plants VII. Flowering plantsÁdicotyledons: Lamiales (except Acanthaceae including Avicenniaceae). Springer, Berlin, pp 2004] and two genera of uncertain subtribal affinities (Heterolamium and Melissa) are documented in order to complete our palynological overview of the tribe Mentheae. Menthinae pollen is small to medium in size (13-43 lm), oblate to prolate in shape and mostly hexacolpate (sometimes pentacolpate). Perforate, microreticulate or bireticulate exine ornamentation types were observed. The exine ornamentation of Menthinae is systematically highly informative particularly at generic level. The exine stratification in all taxa studied is characterized by unbranched columellae. Orbicules are consistently absent in Menthinae. Our palynological data are interpreted in a phylogenetic context at tribal level in order to assess the systematic value of pollen characters and to evaluate the existing molecular phylogenies for this group. Pollen morphology suggests Heterolamium as a close relative of subtribe Nepetinae and supports the molecular affinity of Melissa to subtribe Salviinae.

“…The other characters mentioned can be considered plesiomophic since they are extensively distributed in the family. Epling (1948) acknowledged the lack of synapomorphies for the genus, and instead argued that Lepechinia formed a cohesive lineage based on a "chain" of characters, with the remark that "The only consistent alternative to recognizing one genus…is to recognize eight".…”

“…Most of these taxa occupy temperate forests at high elevations, dwelling in pine-oak, oak, and/or montane cloud forests, though there are some exceptions such as L. mexicana and L. leucophylloides, which grow in more arid conditions. Epling (1948) divided the genus into eight sections. Section Glomeratae Epling was defined to include only one species, Lepechinia glomerata.…”

“…This section is distinctive within Lepechinia due to its sessile flowers arranged in hemispherical glomeruli, which are axillary and long pedunculed, and are subtended at the base by two showy floral bracts. Lepechinia glomerata was described based on specimens from a single collection [Mexia 1804 (MICH, UC, US); Epling, 1948], which was made at San Sebastián del Oeste, Jalisco, in 1927. Since the initial collection, no other specimens have been cited from the same area, even though a floristic survey was conducted and published for that region (Reynoso et al, 2006).…”

La recién descrita Lepechinia flammea fue registrada originalmente solo de la Sierra Madre del Sur en Guerrero, Méxicoco. Sin embargo, durante exploraciones botánicas recientes, una nueva población de esta especie fue descubierta en Jalisco. Por otra parte, fue descrita en Oaxaca como L. oaxacana, nombre que aquí se relega a sinonimia de L. flammea. Además, se redescubre en Jalisco a L. glomerata, la especie más similar en su morfología a L. flammea. Se proveen notas morfológicas de L. flammea, se amplía la descripción de L. glomerata, y se proporcionan fotografías y mapas de distribución de las especies. También se exploran las relaciones de ambas dentro de Lepechinia, además de mostrarse que están más relacionadas con L. nelsonii, una especie de mayor distribución.
