Summary Two divergent opinions have been expressed on the typification of Trichomanes L. Some authors select T. scandens L. as the type on the basis of the first designation of a lectotype by J. Smith in 1875, and according to the taxonomic treatment of the genus after the date of its publication by Linnaeus. Other authors designate T. crispum L. as the type on the basis of the elements studied by Linnaeus up to the time in which the genus was validly published and of the indications to be found in his publications which enable us to ascertain his intent in establishing the genus. The arguments in favour of either lectotypification are thoroughly examined and the nomenclatural consequences of the designation of T. scandens or T. crispum are envisaged. The conclusion is reached that the examination of Linnaeus's publications offers sufficient elements for an objective lectotypification of Trichomanes on T. crispum.
