摘要

Campuloclinium riedelii is reported for the first time in the southernmost part of the intertropical zone, extending its known distribution. Two populations were detected in swampy areas of Santo Tomé and Ituzaingó departments of Corrientes province, Argentina. This study analyses the global distribution and conservation status of the species, classifying it as Near Threatened (NT) according to the IUCN guidelines. Campuloclinium riedelii is found in a few populations restricted to swamps within anthropic areas. Future studies should focus on population trends and habitat stability to reassess its conservation status. This study provides new information, including a detailed morphological description, phenological observations, distribution patterns and an ecological assessment. It contributes to the understanding of the habitat and ecological requirements of Campuloclinium riedelii, offering previously undocumented data. Additionally, a taxonomic key is included to distinguish this species from others growing in Argentina.
