(3047) Proposal to conserve the name Ctenitis against Atalopteris (Dryopteridaceae)

(3047) Ctenitis (C. Chr.) C. Chr. in Verdoorn, Man. Pteridol.: 544. 3 Apr 1938 (Dryopteris subg. Ctenitis C. Chr. in Rosenvinge, Biol. Arbejder Tilegnede Eug. Warming: 77. 3 Nov 1911), nom. cons. prop. Typus: Dryopteris ctenitis (Link) Kuntze) (Aspidium ctenitis Link). (=) Atalopteris Maxon Moran in Davidse Mickel Dong Duan Viveros Proctor, l.c.; Tryon Mickel PPG I, l.c.; Viveros Duek in Adansonia, ser. 2, 11: 722. 1971; Tryon Proctor, l.c.: 415–416; Sánchez in Brittonia 69: 489. 2017, in Revista Jard. Bot. Nac. Univ. Habana 42: 12. 2021). Only Kramer Regalado & al., accepted). The current proposal is made with the aim of maintaining nomenclatural stability. We therefore recommend that the name Ctenitis should be conserved over Atalopteris. This arrangement would prevent the disruption that would result from making more than a hundred new combinations if the name Ctenitis is not conserved against Atalopteris. We are grateful to John McNeill, Werner Greuter, and Rosa Rankin for their advice to solve nomenclatural and typification issues.
