A new species of Pleurothallis from subsection Macrophyllae-Fasciculatae is described and illustrated. The new species is compared with Pleurothallis folsomii from Panama. Pleurothallis celsia is most similar to a group of species with small, yellow flowers but it can be recognized mainly by its lip, which is widely ovate, the surface and margin pi...

... and ecoloGy: Pleurothallis celsia was discovered and described as an epiphyte of secondary vegetation along the edge of the roads (Fig. 3) in the western slope of the Western Cordillera, near a hydroelectric dam within the National Natural Park Farallones de Cali, where the species might be very well protected, due to the access for the general public being highly restricted (Moreno et al. 2020). (Fig 4A) belongs to a group of species with similar, concolorous yellow flowers that mainly differ by the number of veins in the sepals and the shape and indumentum of the petals and lip. The new species is morphologically most similar to Pleurothallis folsomii (Fig. 4B) from Pan-ama as mentioned in the diagnosis, but is also similar to Pleurothallis carduela (Luer) J.M.H.Shaw (Shaw 2016) (Fig. 4C) from Ecuador (Luer 2005), a species that is characterized by having a 7-veined dorsal sepal (vs. ...

... The number of orchid species is estimated to range from approximately 25,000 to 33,000 [2,[6][7][8][9], belonging to 704-850 genera, according to various sources [6,9,10]. Furthermore, new orchid discoveries worldwide continue to increase these numbers [11][12][13][14]. In Europe, the number of species ranges from approximately 163 [3] to around 645 [15]. ...

Orchidaceae is one of the largest and most diverse families of flowering plants in the world but also one of the most threatened. Climate change is a global driver of plant distribution and may be the cause of their disappearance in some regions. Forest orchids are associated with specific biotic and abiotic environmental factors, that influence their local presence/absence. Changes in these conditions can lead to significant differences in species distribution. We studied three forest orchids belonging to different genera (Cephalanthera, Epipactis and Limodorum) for their potential current and future distribution in a protected area (PA) of the Northern Apennines. A Habitat Suitability Model was constructed for each species based on presence-only data and the Maximum Entropy algorithm (MaxEnt) was used for the modelling. Climatic, edaphic, topographic, anthropogenic and land cover variables were used as environmental predictors and processed in the model. The aim is to identify the environmental factors that most influence the current species distribution and the areas that are likely to contain habitats suitable for providing refuge for forest orchids and ensuring their survival under future scenarios. This will allow PA authorities to decide whether to invest more resources in conserving areas that are potential refuges for threatened species.

Eight new species of Lepanthes from the Farallones National Natural Park in Colombia are described and illustrated. These species are morphologically compared with the most similar species to corroborate their identity. Additionally, each of the eight new species is dedicated to a Colombian woman who has made history in several fields in the country, especially in areas traditionally dominated by men. These women serve as a source of inspiration for future generations and highlight the importance of diversity and inclusion in science and conservation. The article aims not only to contribute to the taxonomic knowledge of Colombian flora, but also to emphasize the crucial role that women have played and continue to play in Colombian society and the world.

Colombia is a major biodiversity hotspot, having one of the richest orchid floras in the world. The country spans over a million square kilometers of land, hosting a multitude of different ecosystems thanks to the complexity of its mountainous systems and influences from neighboring countries in Central and South America, as well as the Atlantic and Pacific coastlines. Prior studies found an estimated 3591–4270 species of orchids occurring in Colombia, making it the most species-rich plant family in the country. About 35% of those orchids are members of the Pleurothallidinae subtribe, the largest group in the family and also that with the highest rate of species discovery. Here we record 1862 species of pleurothallids for the country, a significant increase from the 1286–1529 range estimated just a few years ago. We expect Pleurothallidinae to represent close to half the Colombian orchid flora. Colombia hosts roughly one-third of all currently known taxa in the subtribe, and close to 60% of these species are found nowhere else in the world. These are clear indicators that the country is a highly important center of pleurothallid diversity and a key target for their conservation. The most species rich genera in the country are Stelis (521 species), Lepanthes (377 species), Pleurothallis (248 species) and Masdevallia (171 species). Country-level distribution is given for each accepted species. The closest floristic affinity is found with Ecuador, with which Colombia shares over 76% of the non-endemic Pleurothallidinae species, followed in the distance by Venezuela and Peru, with just above one-quarter of the non-endemics being shared. Numerous new country records are presented in the catalogue, many of which are illustrated with color photographs. We provide a full list of homotypic synonyms for each accepted taxon, as well as an annotated list of excluded taxa and newly proposed synonyms. Heterotypic synonyms are not listed, unless they are based on Colombian material. Typification for each accepted species is presented, with lectotypes, neotypes and epitypes being selected whenever necessary and available, as well as information regarding published illustrations.
