Festuca uninodis Hackel (1906: 524) View in CoL

Type:— ARGENTINA. Tucumán: Tafí del Valle, ‘Cerro Muñoz, región de la Puna’, 4150 m, 29 January 1903, M. Lillo 3025b [Herb. T. Stuckert 15, 372] (holotype W 19160004765!, isotypes CORD 00001663!, LIL 44217!, US 341298!).

Festuca stuckertii Saint-Yves (1927: 304) View in CoL . Type:— ARGENTINA. Tucumán: Tafí del Valle, ‘ Río Blanco , Barrancas , 2600 m s.m.’, 26 December 1908. M. Lillo 8873 (holotype G 00099480!; isotypes BAA 00000178 [Col. Typus 1338]!, CORD 00001661 !, LIL 44100 !). Syn. nov.

Taxonomic notes:— Festuca stuckertii View in CoL has been considered as valid for the flora of Argentina taxon. Türpe (1969) mentioned that F. stuckertii View in CoL is clearly characterized by bi-nodes culms, the anatomical structure of their blades with semi-locked vascular bundles, and its florets and anthers are larger than F. weberbaueri View in CoL . Also, Catalán & Müller (2002) considered F. stuckertii View in CoL and F. weberbaueri View in CoL as similar species by their morphology, but they also differ to F. stuckertii View in CoL by their bi-nodes culms, auricles absent, and its midribs of the blade with girder sclerenchymatous present. However, morphological and anatomical characteristics of the taxon to which it was compared, F. weberbaueri View in CoL , are similar to F. fiebrigii View in CoL (Ospina et al. in press). All morphological and anatomical characteristics cited by Türpe (1969) and Catalán & Müller (2012) indicate that F. stuckertii View in CoL has been mistakenly recognized as a species different from F. uninodis View in CoL . The specimens determined here as F. stuckertii View in CoL and the specimens re-determined following the criteria of Türpe (1969) and Catalan & Müller (2012) have characters forming a continuum with specimens of F. uninodis View in CoL . Therefore, F. stuckertii View in CoL is proposed here as a new synonym under F. uninodis View in CoL .
