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...

Palynological characteristics of 30 Salvia taxa in sections Hymenosphace and Aethiopis from Turkey were investigated by light and scanning electron microscopy. S. aethiopis (sect. Aethiopis) has the smallest pollen while S. blepharochlaena (sect. Hymenosphace) has the largest pollen. The basic shape of the pollen grains in most taxa is suboblate, oblate-spheroidal, or prolate-spheroidal to spheroidal; however, subprolate pollen grains are occasionally are found in S. cassia of sect. Aethiopis. Hexacolpate pollen is dominant in all studied taxa, but heptacolpate and octacolpate pollen grains are mixed together in S. palaestina (heptacolpate, 20%) and S. candidissima subsp. candidissima (heptacolpate, 2% and octacolpate, 40%). The exine sculpturing is bireticulate (the common type) or reticulate-perforate. The bireticulate and the reticulate-perforate sculpturing patterns can be divided into subtypes according to the number of primary lumina. Taxonomic implications of the pollen data are also discussed.

“…Resupination is especially well known in orchids, but a number of families of the Lamiales also have some resupinate-flowered species (Clark & Zimmer 2003;Clark et al 2006;Endress 2012). In the Lamiaceae, Salvia jurisicii, from Balkan Peninsula has resupinate flowers, where the pedicels twist through 180° as the flowers open (Schmucker 1929;Turrill 1929;Hill 1939;Classen-Bockhoff et al 2004). Two Mexican species of Salvia, S. gravida and S. vazquezii also have resupinate flowers.…”

“…the pollen is deposited on the dorsal surface of the pollinator. In many Salvia species pollen deposition is facilitated by a hinged staminal lever mechanism (Classen-Bockhoff et al 2004). However, in species of the Ocimeae subtribe Hyptidinae, the central anterior corolla-lobe is boat-shaped, concave, laterally compressed and with an elastic hinge at its base, such that at early anthesis, the declinate stamens are trapped within it and held under tension by the hinge.…”

Resupinate Dimorphy, a novel pollination strategy in two-lipped flowers of Eplingiella (Lamiaceae)

et al. 2017

Th is work provides a summary of the typical fl oral structure of subtribe Hyptidinae (Lamiaceae), in which both style and stamens are declinate within or near the concave anterior corolla lobe. Cross-pollination is facilitated by protandry, acting in conjunction with the explosive release of the stamens and pollen. In contrast, we report that in the three species of the genus Eplingiella we found individuals with either resupinate or non-resupinate fl owers, which represents a novel fl oral dimorphism. In these species of Eplingiella, the style occupies a position towards the posterior corolla lip and opposes the declinate stamens. Th us, in non-resupinate fl owers the pollinating bee receives pollen on its ventral side and makes contact with the style on its dorsal side, whereas in resupinate fl owers, the bee receives pollen on its dorsal side, and contacts the style on its ventral side. Both fl oral morphs seem to be required to achieve cross-pollination. In the two populations studied, each of the two morphs is present and in similar proportions, providing a novel means of promoting cross-pollination and reducing selfi ng. Th e situation in Eplingiella is compared to some other examples of fl oral polymorphism, but appears to be a unique pollination strategy, here termed Resupinate Dimorphy.
