“…In Table 1, we show the differences between N. asuncionesis, N. hispida sensu lato, N. origanifolia from northern Mexico based on descriptions in Hitchcock (1933a, b), Hickman (1993), Pérez Calix & Carranza-González (2005), Shreve & Wiggins (1964), and N. demissa, due to the closeness suggested in the Taylor (2012) As shown in the Table 1, the differentiation between N. asuncionensis and these other taxa is expressed mainly on geographic and habitat criteria, the presence of tiny, rather inconspicuous, capitate glandular trichomes beneath the more obvious non-glandular hairs, the small size of the corolla, the larger seeds, and the compact cushion-like growth form, or pulvinatiform. Some other traits shared with some taxa are the tricolored corolla and the infolded/revolute condition of the leaf margin to some degree, but in N. asuncionensis, this last character is extreme as it is not possible to lift and open the foliar blade without ripping it.…”

Background: Although most of the Nama taxa grow on sandy substrates, none of them is restricted to the coastal dune environment. A small population of a unique looking taxon was found on the Pacific coast of the Baja California peninsula, which is here presented as a new species. Question and/or Hypothesis: In the morphological analysis in the individuals of a putative new taxon, some peculiarities stand out, such as a suffruticose herbaceous perennial growth form with erect and compact branching, featuring a small cushion, unlike the rest of the known species, which are rather procumbent, or erect in form. It also has revolute leaf margins in the blade. Studied Species: Nama asuncionensis sp. nov. (Namaceae) and morphologically similar species. Study Site: Central Pacific coast of Baja California, Mexico. Method: Through bibliographic consultation, review of herbarium specimens, and photographs, a comparative morphological analysis was carried out with other Nama species of the peninsula and mainland Mexico. Results: Based on the comparative analyses, Nama asuncionensis is here presented and illustrated as a new species. Conclusions: Nama asuncionensis is a micro-endemic species restricted to the Pacific coastal environment of the peninsula. We propose that this new taxon be included in the Eunama section of the genus based on its morphological characteristics, including a membranous loculicidal dehiscent capsule, free styles, and sepals divided to the base. This taxon seems to be limited to a narrow coastal strip, with high relative humidity, where it develops its fresh leaves and flowers during the mild season.

Antecedentes y Objetivos: México presenta gran diversidad de flora vascular dada su conformación geográfica, orográfica y climática. Sin embargo, muchos sitios tienen inventarios florísticos incompletos o inexistentes. Es el caso del Área Natural Protegida Parque Nacional El Potosí que, a pesar de ser establecido en 1936, carece de un inventario actualizado de su flora vascular. El objetivo de este trabajo fue generar dicho inventario como un referente de los bosques templados en la Sierra Madre Oriental. Se resaltan las especies endémicas para México, para el estado de San Luis Potosí y regiones adyacentes, así como aquellas que se encuentran en alguna categoría de riesgo. Métodos: Se condujeron recolectas botánicas en un gradiente de 1800 a 2390 m s.n.m., entre junio 2017 y septiembre 2018. Además, se tomaron datos sobre el hábitat, fenología y forma de crecimiento, y se comparó el índice de biodiversidad taxonómica del área de estudio respecto a otras regiones con bosques templados en el estado de San Luis Potosí. Resultados clave: Se registran 354 especies de plantas vasculares en 228 géneros de 83 familias. Las familias con mayor riqueza de especies son Asteraceae, Fabaceae, Fagaceae, Lamiaceae y Polypodiaceae. La biodiversidad taxonómica del área es similar a la reportada en otras regiones con bosques templados en San Luis Potosí. El área incluye 99 especies endémicas de México, seis exclusivas de San Luis Potosí y zonas adyacentes, además de seis especies bajo alguna categoría de riesgo según la NOM-059-SEMARNAT-2010, 16 dentro de los apéndices de la CITES y 14 en alguna categoría de riesgo en la Lista Roja de la IUCN. Conclusiones: La riqueza de especies, su endemismo y diversidad, además de la presencia de especies amenazadas, resaltan la importancia que tiene el Parque Nacional El Potosí como región prioritaria para la conservación de los bosques templados en la Sierra Madre Oriental.

The plant diversity has been and is the main theme of very diverse and different projects due to the need to know and use plant resources in a sustainable way; several factors have been identified that threaten this diversity, such as: the destruction of habitats, environmental pollution, overexploitation of resources, the introduction of exotic species and climate change. Although many and very diverse studies have been carried out on the diversity and vegetation of the country, the biodiversity of many regions and of various groups of plants is still unknown; as are the phanerogams of Oaxaca, which constitute 89.4% of the 255 families reported for the country (Espejo-Serna et al., 2004;Villaseñor, 2004). The 1841 genera represent 69% of the 2677 ocurrung in Mexico and the 8228 species in the state represent 37.3% of the 22397 in the country (Villaseñor, 2004), which shows the great diversity present in the state of Oaxaca. García-Mendoza ( 2004) reported for the state 223 families, 1712 genera and 7804 species of phanerogams, being the angiosperms, the best represented with 217 families, 1700 genera and 7752 species. In an update of these data, García-Mendoza & Meave (2011) reported 228 families, 1841 genera and 8228 species, of which 667 are endemic to Oaxaca. In Villaseñor (2016), 226 families, 1783 genera and 9411 species were reported. The importance of documenting the plant richness in many places is, therefore, cannot be postponed, if we also consider the accelerated destruction of ecosystems and the incomplete knowledge of their components. That is why the objective of this work was to develop an inventory of the phanerogamic flora of the municipality of San Juan Colorado, district of Jamiltepec, located in the south-western part of the state of Oaxaca.Between 2014 and 2017, several botanical collection trips were made to various locations in the municipality, giving preference to the best-preserved areas.Likewise, the specimens deposited in the ENCB, MEXU and UAMIZ herbaria were reviewed to detect the material from the study area. To identify or collate the determination of the specimens, specialized literature was used in each of the study groups. The supporting material collected during the study was deposited in the Herbario Metropolitano (UAMIZ) and duplicates were distributed to institutions in the pedicelo, sobrepuesto, con 2 lóculos, polen con dos alas prominentes como sacos en cada grano; megastrobilos (conillos) en grupos pequeños en el ápice de las ramas, escamas ovulíferas numerosas, leñosas, abiertas en corto período para recibir el polen y cerradas inmediatamente después de la polinización; óvulos 2 por escama. Fruto un cono, simétrico u oblicuo, con numerosas escamas abiertas o cerradas, el umbo dorsal o terminal a la escama variable en grosor, con una cúspide que termina en una espina aguda o gancho, persistente o decidua; semillas similares a nueces, aladas o sin ala, testa suave o endurecida.Género con cerca de 94 especies, para México se han citado 47 especies,
