Description:
Species Description - Rhizome decumbent to erect, stout, 1-2 cm thick (excluding scales), densely clothed with loosely matted, light orange-brown, linear scales up to 2.5 cm long or more, these attenuate at apex, flat or crispate, with distantly ciliate margins. Fronds closely clustered at apex of rhizome, pendent; stipes very short. Sterile fronds up to 80 cm long or more; stipes not sharply differentiated from blades, seldom more than 1 cm long, with weakly defined phyllopodium; blades elongate-linear, metallic blue-green, 1.5-3(-4) cm broad near the middle, narrowed-attenuate at both ends; veins immersed, mostly 2- to 3-forked, with scarcely enlarged tips reaching the cartilaginous margins; tissue thick, coriaceous, opaque, very minutely punctate-scaly on both sides, the scattered scales pale brown, stellate-glandular, and deciduous. Fertile fronds infrequently produced, very much smaller than the sterile ones, with blades 10-16 cm long, 1.5-5 cm broad.
