Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 Treatment submitted for The Jepson Manual [Ed. 2] by Mihai Costea see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Polygonum lapathifolium L. is to be treated as Persicaria lapathifolia (L.) A. Gray in The Jepson Manual [Ed. 2].
Correspondence 2 24 May 2006 e-mail from Jeff Greenhouse see Comment 2
Editorial Comments 2 Correspondence 2 indicates that Persicaria lapathifolia was published by Samuel Frederick Gray (Gray in Authors of Plant Names) in A Natural Arrangement of British Plants 2:270 (1821), based on Polygonum lapathifolium L. (Species Plantarum 1:360. 1753). [Therefore, author citation corrected to Persicaria lapathifolia (L.) Gray, from Persicaria lapathifolia (L.) A. Gray previously in this Index, 30 May 2006.]
Correspondence 3 31 Aug 2012 e-mail from Dave Keil see Comment 3
Editorial Comments 3 Correspondence 3 indicates that the correct author citation is Persicaria lapathifolia (L.) Delarbre. [According to International Plant Names Index, Persicaria lapathifolia (L.) Gray (Nat. Arr. Brit. Pl. 2: 268. 1821) was published about 21 years later than Persicaria lapathifolia (L.) Delarbre (Fl. Auvergne (Delarbre) ed. 2: 519. 1800). In fact, the combination Persicaria lapathifolia was made correctly, in 1800, by Delarbre, who cited "Polygonum lapathifolium. Linn." as basionym. Therefore, author citation corrected to Persicaria lapathifolia (L.) Delarbre, from Persicaria lapathifolia (L.) Gray previously in this Index, 4 Sep 2012.]
