Stipe up to 25 cm long, pale to greyish brown, minutely pubescent to subglabrous. Lamina up to 1.6 × 0.54 m, narrowly elliptic to lanceolate in outline, deeply 2-pinnatifid, apex tapering to a point with a deeply pinnatifid terminal segment, basal pinnae 1 or 2 pairs reduced. Pinnae narrowly lanceolate, ultimate lobes oblong, slightly falcate, apex rounded, margin entire, basal acroscopic lobe enlarged and sometimes overlapping the rhachis; sparsely hairy on both surfaces, more so along the costa and costules; veins 2-3 pairs meeting below the sinus and a single vein joining in the sinus. Rhachis thinly set with long hairs. Sori round, up to 20 per lobe; indusia small, hairy, up to 1 mm wide.
Notes: Christella dentata has 1 pair of veins meeting below the sinus and a single vein joining in the sinus, 1 or 2 pairs gradually reducing basal pinnae. Pneumatopteris unita has an erect rhizome and 4 to 5 pairs of veins meeting below or at the sinus.
C. buchananii look for: creeping rhizome, 2 or 3 pairs of gradually reducing pinnae, 2 or 3 pairs of veins meeting below the sinus.
