Kessler, Michael, Moran, Robbin C., Mickel, John T., Matos, Fernando B. & Smith, Alan R., 2018, Prodromus of a fern flora for Bolivia. XXXV. Dryopteridaceae, Phytotaxa 353 (1), pp. 448-450 : 448-450

Elaphoglossum cardioglossum Mickel, Brittonia 37(3): 266. 1985. ( Fig. 52A )

Range: — Peru ( Mellado & León 2007) and Bolivia (LP).

Ecology: —Local, but fairly common where it is found; terrestrial and epiphytic in humid forests; 3000–3200 m.

Notes: —The veins tend to be relatively widely spaced, about 2 mm apart. The scales on the abaxial blade surfaces are brown to dark brown, not whitish as in many other species of sect. Undulata. The rhizomes are long and creeping, but internode distances can sometimes be short, only several mm apart. Elaphoglossum cardioglossum differs from Peruvian E. pascoense R.M.Tryon only by the narrower dark brown scales on the blades abaxially (vs. broader white scales darkened only at the point of attachment).
