Correspondence 1 indicates that the author citation should be Saxifraga stolonifera W. Curtis (1774), and that Saxifraga stolonifera Meerb. (1775) is a later homonym and thus illegitimate. [Therefore, author citation corrected to Saxifraga stolonifera W. Curtis, from Saxifraga stolonifera Meerb. previously in this Index, 24 May 2011.]
