| Description: |
Rhizome short, erect, up to 10 mm in diameter, producing underground stolons that give rise to new plants at their tips; rhizome scales dark brown with pale brown margins, lanceolate, margin (sub)entire, up to 9 mm long. Fronds tufted, erect to arching, herbaceous. Stipe dark brown, up to 60 cm long, densely set with short, brown hairs and with narrow scales at the extreme base. Lamina 15-45 cm × 15-50 cm, roughly pentagonal to triangular in outline, 3-pinnate to 5-pinnatifid; lower pinnae basiscopically developed, 2/3-3/4 the length of the lamina, upper pinnae less divided. Pinnules shortly petiolate, deltate-lanceolate in outline; ultimate segments oblong-lanceolate, decurrent, rounded, venation free, both surfaces lightly set with short hairs up to 1 mm long. Rhachis, costae and costules thinly pubescent. Sori small, less than 1 mm in diameter, marginal, discrete; indusium small, lunate, (sub)entire, membranous. |
| Notes: | Could be confused with C. multifida or C. pentagona, but these species are (sub)-glabrous, do not have underground stolons and do not occur in forests. |
