Abstract Stauffer, F., L. Ramella, E. Ferreira & L. Noblick (2016). Lectotypification of names proposed by J. Barbosa Rodrigues in the publication “Palmae novae Paraguayenses”. Candollea 71: 105–115. In Spanish, English and Spanish abstracts. DOI: http://dx.doi.org/10.15553/c2016v711a13 In the frame of the treatment of the family Palmae to be published in the Flora del Paraguay, lectotypes are designated for the following names described by J. Barbosa Rodrigues in the publication “Palmae novae Paraguayenses”: Attalea guaranitica Barb. Rodr., Bactris anisitsii Barb. Rodr., Cocos paraguayensis Barb. Rodr. and Cocos sapida Barb. Rodr. The latter is here proposed as a new synonym of the widely distributed South-eastern Brazil - Southern Cone palm Syagrus romanzoffiana (Cham.) Glassman. The fate of the important palm collection gathered by Barbosa Rodrigues is here discussed and notes on the palms described in the publication are added in order to better define their taxonomic identity.
