3. Cleveaceae Cavers View in CoL

Rubasinghe et al. (2011) demonstrated that Athalamia Falconer (1848: 375) and Clevea Lindberg (1868: 289) , previously treated as synonyms, should be recognized as distinct genera, raising the number of genera in the Cleveaceae to four. As a consequence, the genus Athalamia sensu stricto was recognized to contain a single species and the genus Clevea , three species, including the generitype, C. hyalina ( Sommerfelt 1833: 234) Lindberg 1868: 291 ) [≡ Athalamia hyalina (Sommerfelt) S.Hattori in Shimizu & S. Hattori (1954: 54)]. Unfortunately, Rubasinghe et al. (2011) overlooked the earlier name Fimbriaria nana Lindenberg (1829: 109) . which Grolle (1981: 325), after study of the type specimen, concluded should be synonymized with Athalamia hyalina . Fimbriaria nana Lindenberg was published in 1829, four years earlier than Marchantia hyalina Sommerfelt (1833: 234) , published in 1833. The epithet “ nana ” was blocked for use in the genus Athalamia , however, due to the existence of Athalamia nana (Shimizu & S.Hattori 1953: 34) S.Hattori in Shimizu & S. Hattori (1954: 56), but in the genus Clevea the epithet “ nana ” is available for use and the new combination Clevea nana (Lindenberg) Crandall-Stotler & D.G.Long is therefore made to replace C. hyalina , as mandated by Article 11.4 of the ICN ( McNeill et al., 2012). Given the long history of use of the epithet “ hyalina ” for this taxon, whether in Clevea or Athalamia , a proposal to conserve Clevea hyalina (Sommerfelt) Lindberg over Clevea nana (Lindenberg) Crandall-Stotler & D.G.Long is in preparation. However, until conservation has been actually approved, the correct name for this taxon is Clevea nana (Lindenberg) Crandall-Stotler & D.G.Long.
