Abstract:—Cryptanthus is a genus endemic to eastern Brazil from Rio Grande do Norte to Rio de Janeiro and Minas Gerais.After a long search at libraries and European herbaria, a correction is presented to the author designation of aspecies as well as some input about synonymy and morphological variation. Cryptanthus zonatus (Vis.) Beer hasbeen cited by several authors but there is a mistake that has been copied for years. Roberto de Visiani, botanistand director of the Botanical Garden of Padua (Italy) from 1837?1878, published in 1847 on the last page of aindex of plants from the institution a monospecific genus called Pholidophyllum Vis. Under this new genus, he provided a short description of P. zonatum Vis. and P. zonatum ß fuscum Vis. For both taxa, Roberto de Visianialso indicated as synonyms two names which had never been published but were used for cultivated specimens at?Orto Botanico Patavino?. Both names are nomen nudum, indicated and first published as such by Visiani and notby Otto & Dietrich, as cited later in major works in Bromeliaceae. In 1854, Roberto de Visiani published a shortand poorly known paper which was found at the library of University of Padua. In this publication, he proposeda new combination for both taxa, under the genus Pholidophyllum, established by him 8 years previously. Twoyears after that, Beer in his major work about Bromeliaceae and unaware of the recent publication by Visiani,also proposed the same new combinations. No type is clearly indicated in the protologue of both taxa, except forthe indication that the short descriptions were based on cultivated specimens from the botanical garden (?OrtoBotanico?) in Padua. Living specimens had possibly been sent from the Botanical Garden of Genova to Robertode Visiani (at ?Orto Botanico Patavino?) and to Antonio Bertoloni (at ?Horto Botanico Bolognese?). The Bromeliaceae collection at herbaria PAD, where the original collection from Roberto de Visiani is deposited, and BOLO,which also holds some specimens studied by him, were carefully searched and no specimens of Cryptanthus (orunder the name Pholidophyllum or Tillandsia) were found. A correction on the name of the authors as well as a new synonym for C. zonatus are proposed here.
