Fronds monomorphic, tufted, 14-100 cm tall, erect, rigid, herbaceous to coriaceous. Stipe up to 42 cm long, dark brown to almost black, shiny, shallowly grooved, glabrous but with brown narrow scales at the extreme base. Lamina 3-pinnate to 5-pinnatifid, ovate-deltate in outline, lowest pinnae together almost as long as the lamina, basiscopically developed, 5-58 × 2.5-32 cm; pinnae in 5-12 pairs, oblong-ovate in outline, 2-19 x 1-12 cm; pinnules in 6-8 pairs, triangular-oblong to deltate-lanceolate in outline, 0.5-4.5 x 0.4-1.7 cm; ultimate segments oblong-ovate in outline, apex rounded, margin crenate, 0.2-1.5 x 0.1-0.7 cm, both surfaces subglabrous; venation visible or obscure, free; rhachis and secondary rhachises castaneous to black, hairless.

C. pentagona differs in having reddish-brown rhizome scales, a lamina that is less dissected (3- or 4-pinnatifid), pentagonal in outline and with visible venation.
