“…Currently, about 15 percent of the known vascular plant species reported for Panama are considered to be endemic [ 47 ]. An oak species composition analysis recovered nine areas of montane oak endemism in the region between Panama and Mexico that are separated by valleys with a climate that is unsuitable for oaks [ 48 ].…”

Four new species of Russula subsection Roseinae from tropical montane forests in western Panama

Species of the genus Russula are key components of ectomycorrhizal ecosystems worldwide. Nevertheless, their diversity in the tropics is still poorly known. This study aims to contribute to the knowledge of the diversity of Russula species classified in subsection Roseinae based on specimens recently collected in tropical montane rainforests in western Panama. A five gene multilocus phylogeny based on the nuclear markers ITS nrDNA, MCM7, RPB1, RPB2 and TEF-1α was constructed to identify the systematic position of 22 collections from Panama. Four new species, Russula cornicolor, Russula cynorhodon, Russula oreomunneae and Russula zephyrovelutipes are formally described and illustrated. None of the four species are sister species and they are more closely related to North American or Asian species. Two of the newly described species were associated with the ectomycorrhizal tree species Oreomunnea mexicana, while the other two species were associated with Quercus species. All four species are so far only known from mountains in western Panama.

“…Panamá es uno de los países con mayor diversidad biológica a nivel mundial (Olmedo y col., 2018;López y Mainieri, 2019), con 8 de las 200 ecoregiones reconocidas alrededor del mundo y con 21 veces más especies de plantas por km 2 que Brasil (ANAM, 2010). Alrededor de 10000 especies de plantas vasculares se han descrito en el país (Correa, Mireya y Stapf, 2004), sin embargo, esta lista ha incrementado en los últimos años con reportes de especies descritas y nuevos rangos de distribución para Panamá (Flores, Ibanez y Correa, 2016;Flores, Black e Ibáñez, 2017;Flores y col., 2018;Ortiz y col., 2019).…”

El almendro (Terminalia catappa L.) en Panamá es de uso maderable, nutricional, medicinal, entre otros. Se sabe poco sobre los compuestos secundarios presentes en las diferentes partes de esta especie vegetal. Este trabajo tuvo como objetivo realizar la caracterización fitoquímica de la hoja verde (HN), fruto verde (FV) y maduro (FM) del almendro. El muestreo se llevó a cabo entre los meses de mayo a junio del 2017. Se colocaron las HN, FV y FM del almendro por separado en tratamiento de extracción directa con etanol al 95% durante un día. El extracto etanólico fue obtenido por filtrado de gravedad y concentrado en un rotavapor al vacío (BUCHI Rotavapor™ R-210). Se realizó un tamizaje fitoquímico para determinar los tres principales grupos de compuestos secundarios (compuestos fenólicos, compuestos nitrogenados y terpenos). También se realizó un análisis de Espectroscopía Infrarroja (FTIR) y Espectroscopía Ultravioleta-Visible (UV) para saber cuáles eran los grupos funcionales presentes. Se utilizó Past 4.02 para generar una gráfica de abundancia relativa de los compuestos secundarios presentes, y se aplicó el índice de Whittaker para evaluar el porcentaje de diferencia en la composición fitoquímica de las diferentes partes vegetales. Con estos datos se logró identificar que la caracterización fitoquímica semicuantitativa es variable para cada parte, presentando mayor abundancia de compuestos nitrogenados (alcaloides) y compuestos fenólicos (taninos, flavonoides). No se observó presencia de glicósidos cardiotónicos, ni de gomas y mucilagos. Esta información resalta que T. catappa L. es un potencial recurso para la salud, siendo de gran valor etnobotánico, farmacológico y para la industria alimenticia en Panamá.

Background and Aims: Gustavia sessilis is a neotropical tree, belonging to the Lecythidaceae family, until now known from the Colombian Chocó region only. In this paper, we report G. sessilis for the first time for Central America. Methods: Central American specimens of G. sessilis were collected in 2019 from the Darién Province (eastern Panama). Plant identifications were confirmed by comparing collected specimens with those identified earlier and housed in the MO, PMA, SCZ and UCH herbaria. Type specimens were examined by consulting the JSTOR Global Plants database. The estimations of the conservation status were made based on the criteria of the IUCN.Key results: The record of G. sessilis for Central America is presented, based on a collection made from eastern Panama (Darién Province). Photographs, taxonomic comments, and conservation notes are provided. Additionally, a key for the Central American Gustavia species is included.Conclusions: The distribution of G. sessilis now ranges from Bahía Piñas, Darién Province, Panama to the Condoto river, Chocó region, Colombia, highlighting the importance of the Chocó Panama-Colombia region for the conservation of biodiversity, since it could act as a natural corridor for species. Taking into account the small number of records and the restricted natural range of this species, we recommend considering G. sessilis as an endangered species.
