Fronds clustered; stipe short, brittle, usually broken, base or lower portion scaly, upper portion pubescent; lamina 1-pinnate-pinnatifid, lanceolate, gradually tapering to both ends, herbaceous, covered with multicellular glandular hairs; pinnae lanceolate, sessile, articulate to rachis; ultimate segments hemielliptic. Veins free, pinnate, not reaching laminar margin. Sori small, consisting of 4-10 sporangia, submarginal, at veinlet endings, orbicular; indusia inferior, subspherical, sometimes not fully developed, thinly membranous; false indusia formed by pale, thin, reflexed laminar margins. Spores ellipsoid, monolete, wall surface folded, granular. x = 37, 41.
