Meniscium nesioticum (Maxon & C.V.Morton) Pic.Serm, Webbia 23(1): 180: 1968.

= Thelypteris nesiotica (Maxon & C.V.Morton) C.V.Morton, Contr. U.S. Nat. Herb. 38: 29–30. 1967.

Range:— Colombia east to the Guianas and south to Brazil and Bolivia (CO, SC).

Ecology:— Rare; terrestrial in humid forests, sometimes as a rheophyte along stream margins; to 1100 m.

Notes:— Meniscium nesioticum is subdimorphic to dimorphic, with acrostichoid sporangia (between the veins and occupying the entire abaxial surface of the blade); elsewhere in Meniscium this condition is known only in M. macrophyllum Kunze , which so far has not been found in Bolivia. There is also a similarity to M. lanceum (A.R.Sm.) R.S. Fern. & Salino , which has erect, tangled, dense hairs on the costae abaxially.
