Viola sacculus Skottsberg (1916: 266)

Type (lectotype, designated here):— [ ARGENTINA. Chubut: / CHILE. XI Region:] Patagonia andina, sandy meseta no. om Valle Frias / Patagonia , meseta al NE del río Cisnes , ca. 1000 m, 17 November 1908, C. Skottsberg 585 (S07-16851 [digital image!]; isolectotype, S11-34267) .

Protologue citation:—“Andines und subandines Patagonien, in der alpinen Region. Terr. Chubut, Meseta nö. vom Valle Frias, c. 1000 m (Bl. 2, 17.11.08); Terr. Sta. Cruz im Pass zw. dem Koslowsky- und Fenix-Tal, c. 1100 m (Bl. 2, 8.12.08); Schutthalden in den Gebirgen w. vom Rio Zeballos, 1400–1450 m; Nordseite des Zeballos-Passes, 1400– 1500 m.”

Distribution:—Native of Argentina and Chile. In Argentina it is known for the provinces of Chubut, Neuquén, Río Negro, and Santa Cruz.

Notes:—Of the several syntypes mentioned by Carl Skottsberg, we designated as the lectotype the specimen with the barcode number S07-16851, which is complete, agrees with the protologue, and has a label handwritten by Skottsberg with its location and identification. There is another specimen at S with the barcode number S11-34267, which is identified as collected on the same date by Skottsberg, and also bears the same number 585, but the locality given is “Patagonia, meseta al NE del Rio Cisnes, c. 1000 m.s.m.” Since “Río Cisnes” is the alternative name for “Río Frias” we interpret this collection as represent an isolectotype of the species. The Frías river (or Cisnes river) communicates Argentina with Chile through the Río Frias-Río Cisnes international border crossing. According to the report of Skottsberg (1911) in his book “The wilds of Patagonia” it is difficult to state whether this collection was made on the Argentine or the Chilean side of the Andes since he and his fellow travelers were exploring the valleys from one side to another during several days.

= Viola patagonica Becker (1925b: 356)

Type (lectotype, designated here):— ARGENTINA. Neuquén: In pratis alpinis, prope Laguna Blanca, Patagonia Andina Central , ca. 1000 m, January 1898, C.L. Spegazzini s.n. (LP 011391!; isolectotypes, BAF!, SI 003769!) .

Protologue citation:—“Patagonia: in fissuris rupium prope “ Laguna Blanca” (Patagon. central. andin.), leg. C. Spegazzini I.1898; etiam in pratis alpinis ± 1000 m. s. m.)”.

Notes:—When describing this species, Wilhelm Becker (1925b) did not mention where the type was located. We selected the specimen at LP as lectotype since it fully agrees with the protologue, is a well preserved collection, and has a label with the identification made by Becker in 1924. Isolectotypes are housed at BAF and SI.
