Viola comberi W. Becker (1928: 136)

Type:— ARGENTINA. [Neuquén:] Cerro Colohuincul, between San Martín de los Andes and Lago Huechulaufquen , 2100 m, December 1926, H.F. Comber 882 (holotype, K [missing]; lectotype, designated here E 00322371 [digital image!]) .

Protologue citation:— “Argentina , 40º S:Cerro Colohuincul,between San Martin de losAndes and Lago Huechulafquen, 2100 m., Dec. 1926, H. F. Comber 882 (type in Herb. Kew.)”.

Distribution:— Endemic of Argentina; known only for the southwest of Neuquén province.

Notes:—The type collection of this species at K is actually lost (Mariel Sanso and Cecilia Xifreda pers. comm.). Therefore, we selected as lectotype the specimen with the barcode number E 00322371, which is in perfect condition and fully agrees with the protologue of Viola comberi .

Rossow (1988) erroneously synonymized Viola comberi under V. cotyledon . These two taxa are quite distinct as V. comberi is a species with small corollas less than 1 cm long, which are yellow with purple veins, while V. cotyledon has bigger corollas more than 1 cm long, whitish to purplish. We consider V.comberi as an independent species although similar to V. coronifera , both with yellow flowers of similar size.
