[III Region:] Río Frío , February 1854 , R.A. Philippi s.n. (SGO 000003287 [digital image!]; isolectotype , HAL 0117794 [digital image!]) . Protologue citation :—“Fissurae rupium trachyticarum prope Rio Frio (24º50’ lat. mer. et 10600 p.s.m.) panca specimina obtulerunt.” Distribution :—Native of Argentina and Chile . In Argentina it is known for the provinces of La Rioja and San Juan. Notes :—We selected the specimen with the barcode number SGO 000003287 because it agrees with the protologue and is located at the herbarium where Rudolph A. Philippi deposited most of his type specimens when he settled in Chile , although he sent further material to many other herbaria ( Stafleu & Cowan 1983 ). = Viola molfinoana W. Becker (1926b: 351) . Type ( lectotype , designated here) :— ARGENTINA . San Juan : [Calingasta,] Cordillera del Espinazito , Valle Hermoso , in arenosis, 14–16 February 1897 , F. Kurtz 9732 (CORD 003356 [digital image!]; isolectotypes , B [destroyed], BAF 6336!, CORD 003357 [digital image!]) . Protologue citation :— “ Argentina : prov. San Juan, cordillera del Espinalito, valle Hermosa, 2900 m in arenosis II. 1897 , Kurtz Herb. Argentinum no. 9732 ( typus ); herb. W. Bckr. et Inst. de Bot. et Farmacol. Buenos Aires .” Notes :— According to the protologue, the type of Fritz Kurtz 9732 was deposited at “Herbarium Argentinum” (currently CORD; http://museobotanico.unc.edu.ar/historia), with duplicates ( isotypes ) deposited at B (the Wilhelm Becker Viola herbarium, “herb. W. Bckr. ”, which was acquired by the Botanical Museum Berlin-Dahlem, B , in 1929 [ Hiepko 1987 ]) and BAF (the herbarium of the Faculty of Pharmacy and Biochemistry of the University of Buenos Aires , referred to by Becker as “Inst. Bot. et Farmacol. Buenos Aires ”). The collection at CORD consists of two sheets, each one with an original label, from which we selected the specimen with the barcode number CORD 003356 as lectotype since it fully agrees with the protologue, it is an abundant, complete, and well preserved specimen, and has a label handwritten by Kurtz. The material from B is destroyed (Robert Vogt pers. comm.), but other isolectotype is housed at BAF .
