L.E.Bishop, Amer. Fern J. 68(3): 80. 1978 . = Grammitis serrulata (Sw.) Sw., J. Bot. (Schrader) 1800 (2): 18. 1801 . = Xiphopteris serrulata (Sw.) Kaulf., Enum. Fil. 85. 1824. Range: —Greater and Lesser Antilles; central Mexico south to Bolivia (CO, LP, SC) and Brazil ; tropical Africa; Madagascar ; Mascarene Islands. Ecology: —Common but frequently overlooked; epiphytic and less commonly saxicolous, reproducing asexually by proliferous roots and forming colonies, in humid forests, growing among mosses, often along forest margins; 500–1800(2850) m. This is ecologically the most tolerant species among grammitids. It is also the only species of grammitid that we have managed to cultivate (M. Kessler, pers. obs.). Notes: —Sterile blades and sterile portion of fertile blades serrulate. Most easily confused with Stenogrammitis jamesonii (Hook.) Labiak , but that has reddish, forked blade hairs, especially on costae and veins, and grows above 2500 m .
