Festuca argentinensis (Saint-Yves) Türpe (1969: 254)

Basionym: Festuca scirpifolia var. argentinensis Saint-Yves (1932: 138) . Lectotype:— ARGENTINA. Catamarca: Tinogasta, “Reales Blancos”, 4000 m s.m., 2 February 1930, R. Schreiter 6119 (first-step lectotype BAB and LIL, designated by Türpe (1969: 255); second-step lectotype LIL 44139!, designated here; isolectotype MVFA 0000358 (ex LIL)!).

Taxonomic notes:—In the protologue of Festuca scirpifolia var. argentinensis, Saint-Yves (1932: 139) cited the following syntypes: ‘ Argentine. Prov. De Jujuy, Leg Parodi 1931; Alra Pampa. 14-II común in suelos húmidos, Nº 9602; La Quiaca, 12 II abundante en toda le región Nº 9612; 15 II comun en los mallines Nº 9648; et 13 II comun en las vegas, Nº 9657; Humahuaca, 17 II comun en las vegas, forma grandes matas No 9656 (herb. Parodi et herb. St.- Y.); Catamarca: Reales Blancos, 400 m. leg. Schreiter II 1930 Nº 6119 (herb. Schreiter, herb St.-Y.); and ‘ Chili. Dep. Illapel: Cajón de los Pelambres 2900 m. leg. Looser Nº 2151 (herb. Par., herb. St-Y.)’. Later, this taxon was recognized at the species level, as F. argentinensis , by Türpe (1969: 254) who designated ‘ R. Schreiter 6119 (BAB y LIL) as typus speciei ’. This is here considered as a first-step lectotypification because the author mentioned two collections of a single gathering (one deposited in BAB and the other deposited in LIL) but did not specify one of these as the type specimen. The R. Schreiter 6119 collection was not found in BAB, while other specimens of this gathering were found in LIL and MVFA. The specimen at LIL (LIL 44139) is chosen here as the second-step lectotype for the name F. argentinensis because it bears Schreiter´s handwriting, the original material was deposited in LIL, and it is the most complete specimen.
