Sterile lamina up to 6.5 × 5.7 cm., triangular in outline, deeply pinnatifid above becoming pinnate at the base, the lowest pinnae with basiscopically developed lobes; pinna lobes oblong in outline, apex rounded to pointed, margin entire to crenate, thinly pilose on both surfaces with pale flexuous hairs; venation obscure. Fertile lamina up to 10.7 × 7.6 cm., triangular in outline, pinnate above to pinnatifid below, the lowest pinnae with basiscopically developed entire to sinuate lobes; middle pinnae pinnatifid into oblong to triangular obtuse entire lobes thinly pilose on both surfaces with pale flexuous hairs.
