Rhizome erect, c. 3 mm thick; scales brown, 1-5 mm long, margins entire. Fronds tufted, proliferous near the apex, the apical segment above the proliferating bud has less than 5 lobes. Stipe up to 17 cm, greyish-brown, sometimes narrowly winged, subglabrous. Lamina 16-39 cm × 3.5-6 cm, 2-pinnate to 3-pinnatifid, narrowly lanceolate to oblong in outline.
