Dennstaedtia glauca (Cav.) C.Chr. ex Looser, Rev. Hist. Geog. Chile 69: 184. 1932.

Range:— Peru, Bolivia (CO, LP), Chile, and Argentina ( Yañez et al. 2014).

Ecology:— Fairly common; terrestrial in semihumid forests, especially high-elevation forests dominated by Polylepis Ruiz & Pav. , Alnus Mill. , Weinmannia L., or Podocarpus L’Hér. ex Pers. ; 1700–3600 m.

Notes:— Tryon & Stolze (1989) and Yañez et al. (2014) pointed out that slightly pubescent specimens of Dennstaedtia cicutaria could be misidentified as D. glauca , given the similarities in relation to the degree of division of the lamina. They mentioned that a useful character to differentiate both species is the position of the sori: in D. glauca , they are displayed at the margin of the foliar lobes, while in D. cicutaria they are located at the sinuses. Additionally, in the latter species, the petioles are brownish to black and bear abundant roots, whereas in D. glauca the petioles are stramineous and no or very few roots are present.
