| Description: |
Rhizome erect, up to 7 mm diameter; scales up to 6 mm long, lanceolate, attenuate, pale brown. Fronds tufted, not proliferous or occasionally proliferous at the base of the lamina. Stipe up to 23 cm, stipe and rhachis matt brown, glabrous. Lamina 15-40 cm × 4-15 cm, 2-pinnate to 4-pinnatifid, narrowly lanceolate-elliptic in outline, lower pinnae variously reduced. Pinnae glabrous, incised into rhombic pinnules that are divided into 2- to 3-fid or linear acute lobes. Sori linear to oblong (oval when dehisced), not marginal, 2-6 per pinnule, indusium entire. |
| Notes: | Differs from similar species by having oval, not marginal sori and gradually decrescent basal pinnae. It can be distinguished from A. varians by having a more dissected lamina and more rounded lobe margins.
Burrows, J.E. (1990) and Crouch N.R. et al. (2011), distinguish 2 varieties: var. lobatum is 2-pinnate (to 3-pinnatifid), has 2-5 pairs of basal pinnae reduced and is not gemmiferous; var. pseudoabyssinicum is 3-pinnate to 4-pinnatifid, basal pinnae are not reduced and is often gemmiferous on the stipe. |
| Derivation of specific name: | lobatum: lobed; this fern has a separate acroscopic lobe on each pinnule |
