... This discovery is significant as it expands our understanding of the botanical diversity within this park. Despite Altos de Campana National Park being one of the botanically well-documented parks in Panama, as noted by Ortiz et al. (2019), our study reveals that there are still regions within this park that hold undiscovered plants. ...
Matisia Bonpl. is a genus of Malvaceae (Matisieae) that is distributed from Nicaragua to Brazil. Twelve species of Matisia have been recorded in Panama. In this article, we add two species to the Panamanian flora, Matisia gentryi Fern.Alonso and M. tinamastiana A.Estrada & Cascante, and provide for both species full descriptions , images, a distribution map, taxonomic notes, and conservation status. Additionally, we provide an identification key for Matisia in Panama and propose the synonymization of Matisia sect. Tuberculatae Fern.Alonso under Matisia sect. Matisia. Fernández-Alonso JL, Campos-Pineda E (2023) Matisia gentryi and M. tinamastiana (Malvaceae), two species newly recorded from Panama and an updated key to Matisia species in this country.

... Considering previous records on Santa Rita Colon-Panama by Ricklefs et al. (1969) and Roubik & Ackerman (1987). Few flora studies have been carried out in Colón and no formal study have been performed in Santa Rita, where it is believed there is high endemism (Lewis 1971;Ortiz et al. 2019). ...
Santa Rita is a town located in the province of Colón, Panama. This area is threatened by various human activities that not only threaten the landscape and its vegetation, but also the integrity of the pollinators that live there. Considering this, we collected samples of bees from the Euglossini tribe in a fragmented area of Santa Rita, to get an idea of the population status in which these bees could be found at the site. Sampling was carried out one day during the dry season and one day in the rainy season of 2017. We collected 179 males belonging to 20 species, belonging to the three genera Euglossa (14 spp.), Eufriesea (4 spp.), and Eulaema (3 spp.). We know that these results are not enough to determine if Euglossini bee populations are stable or have decreased, but they give us a basis on the abundance and richness of the recorded species.
... In addition, some areas remain little explored in Panama, or it has been difficult to determine species diversity with certainty. For example, recent explorations in BPPS continue revealing new records in the genus, such as Sobralia purpurella Dressler & Bogarín (2011: 309) (Ortiz et al. 2019). ...
In Panama, the Orchidaceae comprise 187 genera, of which one of the most conspicuous is Sobralia. The flowers of Sobralia are mostly ephemeral but colorful, often fragrant, and of variable sizes. Despite being a prominent group, its taxonomy is still underdeveloped in most neotropical countries. To continue with taxonomic studies in the Orchidaceae of Panama, we investigated a species of Sobralia, which differs from any recorded species of the genus. We documented the species with digital images and compared it with morphologically similar taxa. This paper describes and illustrates a new Sobralia from the Bosque Protector Palo Seco in the Fortuna area, Panama. Sobralia rinconiana differs from all other species recorded in Panama by the combination of a large plant size that reaches up to 120 cm high and the larger and broader, elliptical-lanceolate leaves (30–35 × 14–16 cm). Sobralia rinconiana is most similar to S. carazoi but differs in the spreading flowers with reflexed petals and the infundibuliform, cream-yellow lip, the wider, longer sepals and petals, and the longer, suberect column. The accurate estimate of the number of Sobralia species in Panama is still uncertain. Its diversity may increase as new areas are explored or species complexes are resolved.
... 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.
... 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]. ...
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.
... As a result of comprehensive revision of herbarium specimens and recent explorations in poorly explored areas of Panama identified by Ortiz et al. (2019), we recognized two new endemic species of Dieffenbachia, which we describe in this paper. These taxonomic novelties increase the number of Panamanian species to 23, nine being endemic to the country. ...
Dieffenbachia (Araceae) currently comprises 57 species described from Mexico, through Central America, the West Indies, Trinidad to South America. Our comprehensive revision of herbarium specimens and recent explorations in remote areas of Panama, identified two new endemic species of Dieffenbachia: D. batistae O. Ortiz & Croat and D. mortoniana O. Ortiz & Croat. Descriptions, taxonomic comments, conservation notes and photographs of the new species are provided.
... During recent botanical explorations conducted in poorly explored areas identified by Ortiz et al. (2019), specimens of G. sessilis S.A. Mori (sect. Grandibracteata) were collected, which represent the first records of the species in Central America. ...
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.
... Actually, Panama has 436 described species in 26 genera (but it is estimated that there are more than 600 species) and contains 12% of the described species of Araceae in the world (Ortiz et al. 2018). Although it seems that the Panamanian aroid flora is reasonably well known, the knowledge of this group of plants is still poor in several parts of the country, mainly in the Caribbean slope and in the isolated mountains of the Darién Province (Croat 1986b;Ortiz et al. 2018Ortiz et al. , 2019. ...
Ninety-four species belonging to 12 genera of Araceae are recorded on Cerro Pirre (Darién Province): Adelonema Schott (two); Anthurium Schott (39), Chlorospatha Engl.
