Novedades nomenclaturales en la tribu Stipeae (Poaceae, Pooideae) para la Flora Argentina

during the revision of the stipeae (poaceae) for the argentinean flora and in accordance to the latest phylogenetic studies in the tribe, it became necessary to transfer some recently described taxa from the genus stipa to nassella, jarava or pappostipa. as a result, 12 new combinations are here proposed: jarava ichu var. pungens, nassella brachyglumis, n. macrotricha, pappostipa arenicola, p. choconensis, p. colloncurensis, p. frigida var. longifolia, p. jucunda, p. kieslingii, p. mapuche, p. marqueziana and p. zulmae. a key to identify the genera of stipeae in argentina is also included.
