São Paulo: “In campis Batataes, June 1834, Riedel 2300 (Neotype, here designated: LE! in 2 sheets, isoneotypes: B!, G!, K!, P!), syn. nov.

Herzog (1924) described P. chiquitensis on the basis of field observations, but he stated in the protologue that only fragments (parts of an inflorescence, Herzog 114) is the holotype at L. However, the original description and type specimen are insufficient to distinguish the species unambiguously without additional evidence. Thus, on the basis of article 9.7 of the ICBN ( McNeill et al. 2006), we hereby designate an epitype. Paepalanthus chiquitensis is the most widespread and variable species in section Diphyomene , therefore several formerly described species are treated here as synonyms.

Sano (2004) proposed Paepalanthus giganteus as a new name for the later homonym Paepalanthus speciosus (Bong.) Koern. In the protologue, Sano (2004) indicated the collection Riedel 2300 in LE as the holotype of the basionym. However, this material was collected 4 years after the species publication and thus cannot be the holotype. As Bongard (1831) did not clearly indicate a type specimen and no original collection belonging to the same species has been found in LE, we consider the original material lost and designate the specimen cited by Sano (2004) as a neotype for the species.
