Linnaeus (1975a) described Pectis and included within it two species, P. ciliaris and P. linifolia. In 1913 Britton and Brown designated P. ciliaris as the lectotype for Pectis. This lectotypification was accepted by the editors of Index Nominum Genericorum (Plantarum) (Farr et al., 1979). I will present evidence below that the lectotypification of Pectis by Britton and Brown was superfluous and that Pectis was actually lectotypified over 90 years earlier by Cassini.
