Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 10 Sep 2007 e-mail from Richard Moe see Comment 1
Editorial Comments 1 Correspondence 1 indicates that, according to International Plant Names Index, the epithet should be spelled "langsdorffii" [and, indeed, the only name close to this in Authors of Plant Names is Georg Heinrich von Langsdorff (1774-1852), for whom this taxon might have been named]. [Therefore, spelling of epithet corrected to "langsdorffii", from "langsdorfii" previously in this Index, 21 Sep 2007.]
