Epiphytic, clustered. Rhizome short, about 1 cm diameter; scales brown, subulate, 3.5–12 mm long, 0.5–1.5 mm wide. Sterile fronds ovoid, 20–35 cm long, 8–25 cm wide, convex, forming an almost hemispherical mass, at first with sparse minute whitish stellate hairs, later ± glabrous. Fertile fronds narrowly wedge-shaped, 25–35 cm long, 2–4 times dichotomously divided into rounded to acute narrow lobes up to 2.5 cm wide, ± glabrous above, densely covered with minute white stellate hairs beneath. Soral patches generally 4 or 8 per frond, situated near but not at the apices of the ultimate segments and often also around the ultimate sinuses. Fig. 1.
