Viola evae Hieronymus ex W. Becker (1922a: 182)

Type:— ARGENTINA. La Rioja: Sierra Famatina, Cueva de Pérez , 26–28 January 1879, G. Hieronymus & G. Niederlein 370 (holotype, B [destroyed]; lectotype, designated here G 00354840 [digital image!]; isolectotypes, CORD 00003347 [digital image!], CORD 00003348 [digital image!], K 0005350089 [digital image!], SI 003777!) .

Protologue citation:—“Exs.: G. Hieronymus et G. Niederlein, Flora Argentina no. 370: Cueva de Perez, Sierra Famatina, Prov. de la Rioja , fl. 26–28. I. 1879 (Herb. Mus. bot. Berol.).”

Distribution:—Endemic of Argentina; it is known for the provinces of La Rioja and Salta.

Notes:—Wilhelm Becker cited as type of this species a collection deposited at the herbarium of Berlin (“Herb. Mus. bot. Berol.”) but this specimen was destroyed (Robert Vogt pers. comm.; Hiepko 1987). We therefore selected the specimen with the barcode number G 00354840 as lectotype because it is an abundant and complete specimen, agrees with the protologue, presents a label with clear handwritten field notes by Georg Hieronymus, and in particular because it includes a label with the identification made in 1927 by Becker.

≡ Viola flos-evae Hieronymus , nomen nudum, pro syn.

Notes:—The collection G. Hieronymus & G. Niederlein 370 consisted at least of two specimens labeled as “ Viola flos-evae Hieron. n. sp. ” deposited at CORD and SI plus three specimens labelled as “ Viola evae Hieron. n. sp. ” deposited at B, G, and K. Georg Hieronymus dedicated his new species to his wife, Eva, but he died in 1921 without ever having formally presented the taxon in print under any epithet. Wilhelm Becker examined the specimen at B in 1922 or before (and later at G in 1927), and described and published it validly as Viola evae Hieronymus ex W. Becker. Subsequently, Benkt Sparre in 1950 and Luis Ariza Espinar in 2010 examined the specimens at CORD and correctly labelled them as “ Viola evae Hieron. ex Becker ”.
