Tectaria pascoensis A.Rojas, Revista Biol. Trop. 49(2): 480. 2001.

Range: — Peru and Bolivia (CO, LP).

Ecology: —Rare, known from two Bolivian collections (Kessler 11443, LPB, UC; Kessler 13235, LPB, UC); terrestrial in humid montane forests; 1250–2400 m.

Notes: —This is the largest species of Tectaria so far known in Bolivia, with an erect caudex, fronds attaining perhaps 2 m (specimens seen incomplete), petioles to nearly 1 cm wide, proximal pinna pair to ca. 50 × ca. 30 cm, lowermost lateral pinnae incised nearly to the costae, strongly decurrent, basiscopic lobe (pinnule) the longest, 25+ cm long, ca. 10 cm wide, incised to ca. 4/5 its width; costae, costules, and costulets abaxially with dense, short-glandular hairs ca. 0.1–0.15 mm, costae, costules, and veins adaxially glabrous; sori in two ± regular rows between main lateral veins of pinna lobes; indusia dark brown, round-reniform, ca. 1 mm diam., glabrous or nearly so. Perhaps most closely allied to T. lizarzaburui , although Rojas-Alvarado (2001) compared it to T. athyrioides (Baker) C.Chr. , from Nicaragua to Panama.
