same habitat or across habitats in the region and a small population size. Porroglossum parsonsii should probably be categorized as Critically Endangered on the IUCN Red List as it has a restricted distribution (area of occurrence ,500 km2, criterion B; IUCN, 2012), with a small number of individuals (,50, criterion D), and there is an inferred past population reduction based on the reduction of habi- tat in the landscape, although the landscape still has high structural connectivity and habitat availability. A full Red List assessment will require additional information on pop- ulation dynamics, and further surveys in the surrounding areas are required to identify whether there are any additional populations. Porroglossum parsonsii is traded at a price of USD 18–20 per plant (based on the websites Equaflor-A, 2019, and


Ecuagenera, 2023), with the origins of these traded plants being unknown. We speculate that individuals were taken from the wild (either from the localities we report here or from others nearby) and grown in nurseries, as mentioned in the holotype. Illegal collection of native species is one of the greatest threats to orchid diversity (Wraith & Pickering, 2018), although the full impact of this on abundance in the wild is unknown (Hinsley et al., 2018; Morton et al., 2021). However, frequent illegal collections from orchid populations have led to local reductions in the number of adult individuals and could affect phenological cycles (Emeterio-Lara et al., 2021). We recommend that Santuario de Fauna y Flora de


Iguaque integrates P. parsonsii into its strategic plan for the conservation of threatened species (Díaz, 2020). This
