Description |
Rhizome creeping, c.5 mm diameter; rhizome scales dark brown, subentire, with a long hair tip, up to 4 mm long, linear-lanceolate. Fronds spaced apart. Stipe up to 26 cm, as long or longer than lamina, dark brown to black, glabrous at age. Lamina 2-pinnate to 3-pinnatifid, 15-25 cm × 10-14 cm, ovate to triangular in outline, basal pair of pinnae longer than those above. Pinnae ovate to triangular. Pinnules obcuneate to oblanceolate, 4-14 mm broad, apical margin irregularly serrate and incised, dark green glabrous above, below paler and glabrous distally and with scattered, black hair-like scales near base and secondary rhachises. Rhachis black proximally, matt green distally, with scattered dark scales and hairs. Sori numerous, linear, set along the veins, indusium entire. |
Notes | Confusion possible with A. aethiopicum complex. A. sebungweense has an almost triangular frond, a longer stipe and a thin and more widely creeping rhizome; sori born on the side margins not on the tips of the ultimate lobes. |
Derivation | sebungweense: named after the Sebungwe region in Zimbabwe. |
Habitat | Dry, deciduous woodland, in deep ravines; on earth banks in deeply shaded, seasonally moist situations along perennial or seasonal streams. |
