Description: |
Rhizome shortly creeping, up to 3 mm in diameter, rhizome scales whitish to pale brown, up to 3mm long, linear to narrowly lanceolate in outline with entire margins. Fronds tufted, erect, slightly dimorphic with fertile fronds a bit longer and narrower than sterile fronds. Stipe 1.5-3.6 cm long, strawcoloured, sparsely set with hairs and pale brown scales. Lamina herbaceous, 6-18 cm long, narrowly elliptic to narrowly oblong or oblanceolate in outline, pinnate to deeply 2-pinnatifid; secondary rhachises narrowly winged. Pinnae above sparsely to densely hairy, below sparsely to densely set with hairs and slender thread-like; pinnule distal margins irregularly crenate to finely incised. Rhachis densely set with whitish hairs and a few larger, lanceolate scales. Sporangia marginal, under a partially reflexed pinnule margin; exindusiate. |
Notes: | The other Mohria species have an upper lamina surface that is more glabrous, the hairs and scales are mostly confined to the secondary rhachises. |
