Abstract

We describe 4 new records of Habenaria dutrae Schltr., a threatened orchid species that is endemic of Rio Grande do Sul state, Brazil. The new record, from Pontal da Barra, increases the distribution of H. dutrae by approximately 180 km south and represents the southernmost known location for the species. We also re-evaluate the conservation status of the species including the new records, finding it to be Endangered under criteria B2ab(iii); D.
