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.
