Quesnelia is subdivided into two subgenera: Quesnelia subg. Quesnelia and Quesnelia subg. Billbergiopsis. The purpose of this work was to conduct a taxonomic study of Quesnelia species from Paraná state (southern Brazil) along with morphological and taxonomic analysis of in vivo material and specimens in herbaria collections. Three taxa were found: Quesnelia humilis, Q. Imbricata and Q. testudo. This work presents identification keys, morphological descriptions, geographical distribution, comments, illustrations and the conservation status of the studied taxa.
