Abstract

The rediscovery of Erigeron morelensis, not collected since 1898, is reported. Between 2021 and 2022, E. morelensis was recorded at two sites in the northwestern canyons of Cuernavaca, Morelos, Mexico, which are subjected to degradation pressure. The morphological description is updated and complemented, and a key for E. sect. Erigeridium is included. Data about the known distribution, ecology and habitat of the species are provided. Based on the IUCN criteria, it is recommended that the species be listed as Critically Endangered (CR).
