Vetensk. Acad. Handl. 1817 (1): 72, t. 3, f. 3. 1817. = Blechnum delicatum Maxon & C.V.Morton, Bull. Torrey Bot. Club 66: 41. 1939 . Range:— Colombia to Guianas and Argentina ; in Bolivia in BE, CH , CO, LP, PA, SC. Ecology:— Common; terrestrial in humid and semihumid forests, usually in open sites such as roadsides or forest edges; to 1400(–2100) m. Notes:— Variable in size, pubescence of petioles and rachises (glabrous to densely glandular-pubescent), and pinna shape (pinnae as long as broad to>5 times longer than broad); a possible species complex, or hybridization may be occurring with other species. Long-petioled, gland-bearing plants with short pinnae have been called Blechnum delicatum ( type from Bolivia ), but are here considered to fall within the range of variability of B. asplenioides .
