Description: |
Rhizome creeping, c. 2 mm thick; scales grey-brown, lanceolate, entire, up to 2 mm long. Fronds spaced apart, erect, pinnatifid, sub-coriaceous to coriaceous. Stipe light-brown to black, up to 6 cm long, scattered with minute, pale brown scales, very narrowly winged. Lamina up to 17 × 1.7 cm, narrowly linear-elliptic in outline, glabrous, decrescent below, pinnatifid to the midrib into entire rounded oblong to quadrate lobes; midrib black, venation obscure. Sori 1-4 per lobe, intramarginal, set with castaneous hair-like paraphyses, exindusiate. |
Notes: | Can be separated from other species by its large size, widely creeping rhizome and fronds which are incised almost to the midrib. |
Derivation of specific name: | flabelliformis: fanshaped; unclear reference as the fronds are linear. |
