Festuca fimbriata Nees (1829: 472)

Type:—BRASIL [ URUGUAY]. [Montevideo]: ‘ Habitat ad Monte-video’, s.d., F. Sellow s.n. (holotype B 10 0002567 !; isotypes B 10 0002568!, HAL 0107005!, LE 00000731!, LE 00000732 (ex B)!, US 557541 (ex B)!, US 1441522 (ex B)!, US 1126679 (fragm. ex W)!, W 18890252147 !).

Festuca ampliflora Döll (1878: 116) . Lectotype:— BRASIL. State of Minaru [Minas Gerais]: ‘Habitat in prov. Minarum’, February 1846, A. F. Regnell III 1409 (first-step lectotype S, designated by E.B. Alexeev (1984a), second-step lectotype S S04-1260! designated here, isolectotypes S S04-1259!, P 00625301!).

Taxonomic notes:— Döll (1878: 116) cited in the protologue of F. amplifora two syntypes ‘Habitat in prov. Minarum (Widgren) e. Gr. ad Caldas (Regnell III n.1409)’. Later, Alexeev (1984a: 348) indicated as lectotype the specimen ‘Herb. Brasil. Regnalli III, nº 1409, prov. Minas Geraes, Caldas, II 1876, Widgren (S)’. This is here considered a first-step lectotypification. Many inconsistencies between Alexeev´s publication and Regnell and Widgren´s collections considered as type material were found, because many specimen deposited in S and their duplicates deposited in other herbaria did not have consistent in the label data and the name of the collector that has been attributed to each of the different specimens. In addition, the specimen chosen as lectotype by Alexeev is not clearly indicated as one of these collections found (S, US, W), which differ in the collector and date of collection that have been attributed as type materials of the name F. ampliflora . Alexeev´s lectotypification needs to be clarified. A specimen at S (S04-1260) is chosen as the second-step lectotype for F. ampliflora , because its label bears the same date, collector, number of collection, and type-locality cited in the protologue, and it is the most complete specimen.
