[IV Region:] los Patos, Coquimbo provintia, 1240 ft , February 1843 , C. Gay s.n. (P 00756163 [digital image]!). Protologue citation :—“Esta muy pequeña violeta que dedico al Señor Domeiko, profesor de química y mineralogía en el instituto de Coquimbo , se cria en los llanos húmedos de las cordilleras de los Patos á una altura de 1240 pies.” Distribution :—Native of Argentina and Chile . In Argentina it is known for registers in Mendoza and San Juan provinces. Notes :—We selected the specimen with the barcode number P 00756163 as lectotype since it agrees with the protologue and is a complete specimen. Considering the spelling “domeikoana ” presented by Gay (1845) and the incorrect orthographical rendering of it by later authors, we clarify here that the exact spelling of the specific epithet according to the author of the species in the original publication and following the International Code of Nomenclature (Art. 60.1; the original spelling of a name or epithet is to be retained […]) is “domeikoana ” with “i”, and not with “y” as “domeykoana”. Few sources of basic reference spell the epithet correctly (e.g. The International Plant Names Index 2012 ). However, it is still published with “y” in many influential works and by many sources (e.g. Marticorena & Quezada 1985 ; Rossow et al. 2003 ; Sanso et al. 2008 ; The Plant List 2013 ).
