Resumen:
Salt glands were observed in two species of Pappophorum, belonging to the tribe Pappophoreae (Chloridoideae, Poaceae). Glands resemble those described in other genera of the Gramineae; they comprise two cells, a large basal one and smaller upper one. Gland density per unit surface was much higher in P. philippianum, a facultative halophyte, than in P. pappiferum, a glycophyte. The relevance of the recretion process for the elimination of accumulated Na in these two species is considered. The evolutionary significance of the presence of glands in Pappophoreae and other members of the Chloridoideae is discussed.
