  • Pollination Ecology, Breeding System, and Conservation of Butia lallemantii Deble & Marchiori (Arecaceae): A Useful Dwarf Palm Tree from the Pampa
    Oscar Perdomo, Rafael Becker, Rodrigo Bustos Singer
    Plants, 2024
    The Dwarf Palm, Butia lallemantii Deble & Marchiori, is an endangered species endemic to the Pampa biome and typically grows in sandy and rocky soils. Given its economic, ecological, and cultural relevance, it is crucial to understand the ecology and biology of this species to encourage its preservation and highlight its significance for the Pampa. This study aims to investigate whether this palm relies on animal vectors for pollination, analyze its breeding system, and propose strategies for its conservation and sustainable use. We conducted field observations on pollination ecology, identified floral visitors, and designed six breeding system experiments to test cross-compatibility, self-compatibility, and apomixis. Additionally, we conducted a literature review to propose conservation strategies. Butia lallemantii is pollinator-dependent and self-compatible. The flowers are mostly melittophilous and offer pollen and nectar for floral visitors. The main pollinators are native Meliponinae and Halictinae bees and the introduced Apis mellifera. This study represents the first comprehensive and complete examination of the breeding system and pollination process on Butia palms. This palm can provide materials for industries, but urgent actions are needed to preserve the remaining populations through effective policies and strategies. Furthermore, this palm should be integrated into diversified agroecosystems to evaluate its adaptability to cultivation.
  • Conservation assessment of five new records for the Orchidaceae of Colombia
    Oscar Perdomo, Alejandro Zuluaga, Edwin Trujillo-Trujillo
    Check List, 2024
    Following the IUCN criteria, we assess the risk of extinction for five orchid species recorded for the first time from Colombia: Acianthera viridis (Luer & Hirtz) Luer, Dichaea lankesteri Ames, Epidendrum lavendulum Hágsater, Masdevallia ariasii Luer, and Stenia stenioides (Garay) Dodson & R.Escobar. We propose a preliminary global Red List categories of Endangered, Least Concern, Endangered, Vulnerable, and Least Concern, respectively, for these species. The main threats of these orchids are habitat degradation, small and degraded AOO and EOO, and a small number of known populations. The Caraño river basin, where these species occur in Colombia, is an important site for orchid conservation. Consequently, strategies are needed to ensure its preservation.
  • Campylocentrum luzmariae (Vandeae, Orchidaceae), a new species from the Andean cloud forest of Colombia
    OSCAR PERDOMO, RODRIGO B. SINGER, EDLLEY M. PESSOA
    Phytotaxa, 2024
    The Andean forests of Colombia harbor high plant biodiversity, especially orchids. Here, we propose and describe a new species of Campylocentrum from the cloud forests of the eastern Andean slopes of Caquetá, Colombia. The new species resembles C. alvesii, from which it differs by the longer lip with obtuse lateral lobes, and C. asplundii, from which it differs by inflorescences shorter than the leaves, trilobed lip, and strongly recurved spur.
  • Epidendrum chloronanum (Orchidaceae): first record for the flora of Colombia
    Javier Cuellar, Nilmar Gómez, Edwin Trujillo-Trujillo, Oscar Perdomo
    Revista De La Academia Colombiana De Ciencias Exactas Fisicas Y Naturales, 2024
    Orchidaceae es un grupo de plantas de gran diversidad. Una quinta parte de sus especies se encuentran registradas en Colombia, principalmente en la cordillera de los Andes. En el departamento de Caquetá se han reportado más de 400 especies, 70 de ellas del género Epidendrum. Reportamos por primera vez la especie Epidendrum chloronanum en los bosques de niebla de la vertiente oriental de la cordillera Oriental de los Andes, en el departamento de Caquetá. Categorizamos la especie como de “preocupación menor” en el país según los criterios de la Unión Internacional para la Conservación de la Naturaleza – UICN. Por último, proponemos algunas estrategias de conservación in situ, ex situ y circa situm que pueden aplicarse para proteger esta especie.
  • Extinction risk categorization and first record for Colombia of Cycnoches suarezii (Orchidaceae, Catasetinae)
    Alejandro Lizcano, Danny Sánchez-Cortez, Edwin Trujillo Trujillo, Oscar Perdomo
    Acta Botanica Mexicana, 2024
    Antecedentes y Objetivos: La subtribu Catasetinae (Orchidaceae) está compuesta por 354 especies pertenecientes a ocho géneros, Catasetum, Clowesia, Cyanaeorchis, Cycnoches, Dressleria, Galeandra, Grobya y Mormodes, distribuidos en el Neotrópico. El género Cycnoches abarca 34 especies, 11 de las cuales están registradas para Colombia. En el presente artículo reportamos a C. suarezii por primera vez para este país, establecemos su categoría de riesgo de extinción siguiendo los lineamientos de la UICN, y planteamos estrategias para su protección y conservación. Métodos: Las poblaciones que reportamos se encontraron durante expediciones botánicas en el piedemonte Andino-Amazónico, en los municipios El Doncello y Florencia, ambos en el departamento Caquetá. La categorización del riesgo de extinción se basó en el criterio B de la UICN, que considera datos de distribución, número de registros y estado de conservación del hábitat. Finalmente, realizamos una revisión de experiencias de conservación desarrolladas con otras orquídeas para proponer estrategias para la protección de C. suarezii y su hábitat. Resultados clave: Presentamos el primer registro de C. suarezii para Colombia mediante dos poblaciones halladas en los municipios Florencia y El Doncello, departamento Caquetá. Con este registro, la riqueza del género en Colombia se incrementa a 12 especies. Proponemos la categoría En Peligro (EN) a nivel global debido al bajo número de poblaciones, el deterioro de su hábitat por causa de la deforestación, la cual supera 20% de la Extensión de Presencia (EOO) en las últimas dos décadas. Conclusiones: Cycnoches suarezii se suma a la orquideoflora de Colombia y el piedemonte Andino-Amazónico del departamento de Caquetá. Proponemos estrategias in situ, ex situ y circa situm para su conservación y la de su hábitat.
  • First documented records and status conservation categorization of Dressleria dodsoniana and Galeandra minax (Orchidaceae; Catasetinae) from Colombia
    Albeiro Rojas-P, Edwin Tujillo Trujillo, Oscar Perdomo
    Revista Peruana De Biologia, 2023
    Registramos la presencia de Dressleria dodsoniana y Galeandra minax en Caquetá, Colombia, basados en dos poblaciones encontradas en la vertiente oriental de la Cordillera Oriental de los Andes y en el piedemonte Andino-Amazónico, respectivamente. Estas especies han sido previamente reportadas para el país en documentos impresos y en bases de datos, pero, sin la mención de ejemplares de herbario, siendo los registros fotográficos la única evidencia para su registro. Nuestros reportes resaltan la necesidad de confirmar la identidad y ocurrencia de las especies con la inclusión de colecciones botánicas en herbarios. Categorizamos ambas especies para Colombia como Críticamente Amenazadas (CR), debido principalmente, al deterioro de su hábitat y por el conocimiento de una única población registrada.
  • MASDEVALLIA LEONOR-BAEZIANA (PLEUROTHALLIDINAE): A NEW SPECIES FROM THE ANDEAN-AMAZONIAN FOOTHILLS OF CAQUETÁ, COLOMBIA
    Oscar Perdomo, Edwin Trujillo Trujillo, Adam Karremans
    Lankesteriana, 2023
    We describe and illustrate a new species of Masdevallia from the Andean-Amazonian foothills of Caquetá, Colombia. Masdevallia leonor-baeziana belongs to Masdevallia subsect. Saltatrices, within the M. constricta group. It is most similar to M. constricta, but it can be distinguished by the shorter sepals and sepaline tails that do not surpass the tube length, and the shorter, sigmoid-ovate lip. We proposed categorizing the species as Critically Endangered (CR) based on the B and D IUCN red list criteria.
  • On the distribution and conservation of Sievekingia hirtzii Waldvogel (Orchidaceae, Stanhopeinae): first records from Colombia
    Natalia Rodríguez-S, Albeiro Rojas-P, Alejandro Lizcano, Edwin Trujillo Trujillo, Oscar Perdomo
    Check List, 2023
    We newly report two populations of the orchid Sievekingia hirtzii in the Andean–Amazonian foothills of Caquetá, Colombia. Following the B criterion of the International Union for the Conservation of Nature, we propose the categorization of this species as Endangered, due to its small Area of Occupancy and Extent of Occur-rence, the limited number of populations, and habitat fragmentation and degradation caused by the expansion of agriculture. Additionally, we propose actions for in situ and ex situ conservation of this orchid, including habitat protection and cultivation in botanical gardens.
  • Checklist of Orchidaceae from Caquetá, Colombia
    Tatiana Arias, Jeisson Chaux-Varela, Maria del Pilar Camero, R. Alexis Calderon-Álvarez, Anyi Carolina Trujillo, et al.
    Phytokeys, 2023
    A checklist of Orchidaceae from Caquetá, Colombia is presented here. We recorded 98 genera and 418 species, exceeding a previous inventory by 276 species. The checklist is conservative in the number of genera and species by including only taxa that were fully and reliably identified and that are either linked to a corresponding herbarium voucher, a living collection specimen or a photo taken in the field and published in iNaturalist by one of the authors or a collaborator. The documented species diversity in the region could dramatically increase in the next few years with additional collecting efforts in the eastern slopes of the Andes nested in Caquetá. About 9% (418/4600) of all Orchidaceae species recorded for Colombia are reported for this area, showing the important contribution to orchid diversity of Andean-Amazonian foothills of Caquetá.
