Plants epiphytic. Rhizome 3– 5 mm wide, short-creeping to erect; rhizome scales 5– 9(–13) mm long, linear-lanceolate, orange to dark brown, denticulate to ciliate, base truncate to slightly cordate or stalked, apex filiform to tortuous. Sterile leaves 20 – 36(– 50) cm long, approximate; phyllopodia present, not obscured by the petiole-base scales; petiole 8 –15(– 21) cm long, 1/3 –1/2 the length of the sterile leaves; larger petiole scales 3– 5 mm long, dense, spreading, lanceolate to oblanceolate, orange to dark brown, sometimes mottled or darker at the point of attachment, ciliate, base truncate, sometimes short-stalked, apex acute; smaller petiole scales 0.5 –1 mm long, dense, oftentimes hidden by the larger ones, oblanceolate to round, orange to dark brown, or mottled, ciliate, base truncate to stalked, apex acute; lamina 11– 24(– 30) by 3– 5 cm, oblanceolate to lanceolate, coriaceous, base broadly cuneate to obtuse, apex obtuse; veins 1–2 mm apart, at an angle of 75– 80° with respect to the costa; adaxial laminar scales 1–2 mm long, scattered, oblanceolate, white to light brown, ciliate, base cordate to truncate, apex acute; abaxial laminar scales 0.5 –3 mm long, from absent to scattered, when present slightly elevated above the surface of the lamina and never imbricate, lanceolate to round, orange to dark brown, sometimes mottled with lighter margin, ciliate, base truncate to short-stalked, apex acute; abaxial costal scales 0.5 –2.5 mm long, dense, pointing forward to the apex, not elevated, lanceolate to round, dark brown, sometimes mottled, ciliate, base cordate to truncate, apex acute; marginal scales 0.5 –1 mm long, dense, oblanceolate, orange, ciliate, base truncate, short-stalked, apex acute. Fertile leaves longer than the sterile leaves; petiole 3/5 –5/7 the length of the fertile leaves; petiole scales same as the ones of the sterile leaves; lamina 9 –15 by 1.5– 2 cm, narrowly-elliptic to linear-lanceolate, coriaceous, base truncate, apex obtuse; adaxial laminar scales 0.5 –1.5 mm long, dense, oblanceolate to round, orange to dark brown, sometimes mottled, long-ciliate, base truncate to cordate, apex acute; abaxial costal scales 0.5 –1.5 mm long, dense, pointing forward to the apex, slightly elevated, oblanceolate to round, orange to dark brown, sometimes mottled, long-ciliate, base truncate to short-stalked, apex acute; intersporangial scales 0.5 –1.5 mm long, scattered, not obscuring the sporangia, lanceolate to oblanceolate, orange, sometimes mottled, long-ciliate, base truncate, apex acute to filiform. Spores papillate, without ridges.

Notes — Elaphoglossum novogranatense can be distinguish- ed by its epiphytic habit, short-creeping to erect rhizomes, appressed, dark brown abaxial costal scales, and papillate spores. The abaxial lamina surface is always visible, prominently veined, and either glabrous or sparsely scaly. Elaphoglossum novogranatense is similar to E. glabrescens , from which it can be distinguished by its appressed, dark brown adaxial costal scales, and the presence of intersporangial scales. In contrast, E. glabrescens has appressed to spreading, orange to dark brown, sometimes mottled with lighter margin or darker at the point of attachment costal scales, and lacks intersporangial scales.

See E. aschersonii for a comparison with that species.

The specific epithet refers to New Granada ( Nueva Granada), a former name for Colombia, after which the species is named.
