| Description: |
Rhizome short, creeping, c.5 mm in diameter; rhizome scales lanceolate, brown to rust-coloured with dark brown central stripe, apex slowly tapering to a point, margin entire, up to 3 mm long. Fronds tufted, erect to arching, deep green, herbaceous to thinly coracious. Stipe dark brown to blackish, shining, up to 44 cm long, about as long as the lamina, grooved in the upper part, practically hairless but set with hairlike scales towards the base. Lamina varying in size, shape and dissection; up to 50 cm × 24 cm, lanceolate to ovate to broadly triangular in outline, mostly 2-pinnate to 3-pinnate, rarely more divided; lower pinnae the largest and occasionally somewhat basiscopically developed. Pinnules variable, oblong-lanceolate, apex rounded to pointed, base cordate to hastate, margin entire to minutely crenate, venation free, distinct, both surfaces hairless or slightly hairy on the veins. Rhachis and secondary rhachis dark brown to black, shining, broadly grooved, hairless or with hairlike scales, always pubescent in the axils. Sori marginal; indusium continuous, subentire. |
| Notes: | Could be confused with C. quadripinnata which is more divided (lamina 4-pinnatifid to 5-pinnate), has strongly developed basiscopically basal pinnae and veins that are obscure on the upper surface. C. virides var. glauca has a rhachis that is deeply grooved with a lighter coloured wing, the secondary rhachis and petiolules are hairless or set with filiform appressed scales. |
| Derivation of specific name: | viridis: green, alluding to the green colour of the fronds |
