Status: | Native |
Description: |
Rhizome short, creeping, up to 4 mm in diameter; rhizome scales brown with pale margins, awl-shaped, margin (sub)entire, up to 3.5 mm long. Fronds tufted, erect, rigid, herbaceous to coriaceous. Stipe dark brown to almost black, up to 42 cm long, shallowly grooved, glabrous but with brown narrow scales at the extreme base. Lamina 5-32 cm × 2.5-28 cm, ovate-deltate in outline, 3-pinnate to 5-pinnatifid; lowest pinnae together almost as long as the lamina, basiscopically developed. Pinnules triangular-oblong to deltate-lanceolate in outline, cut to the midrib into oblong-ovate, rounded, crenate lobes, venation obscure, free, both surfaces subglabrous. Rhachis and secondary rhachises castaneous to black, hairless. Sori small, round, marginal, discrete; indusium small, semicircular, pale, erose to lacerate, membranous. |
Notes: | Could be confused with C. bergiana or C. pentagona. C. bergiana is lightly hairy, has underground stolons and is a forest species. 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.
Two subspecies may be distinguished depending on whether the indusium is erose (subsp. multifida, not in Zimbabwe) or lacerate (subsp. lacerata, in Zimbabwe). |
Derivation of specific name: | multifida: with many divisions, referring to the finely divided lamina. |
Habitat: | Rock crevices and around boulders in grassland, margins of sheetrock, forest margins in high rainfall areas. |
Altitude range: (metres) | 430 - 2500 m |
