Frequency:
Status: Native
Description:
Rhizome erect or procumbent, c.4 mm in diameter, scales brown, lanceolate, margin paler sometimes toothed. Fronds not proliferous, tufted, erect to suberect. Stipe short, up to 60 mm long, chestnut to dark chestnut brown; scales shining, narrowly triangular, with rust-red central region and broad light margins, c. 5 mm long. Lamina 8-19 × 2-5 cm, pinnatisect to pinnate (sometimesshallowly 2-pinnatifid), elliptic to obovate in outline, herbaceous, inrolled when dry; basal pinnae gradually decrescent. Pinnae attached to the rhachis with the base prolonged down to the rhachis towards the lamina apex, becoming free from the rhachis with a somewhat flared auriculate-heartshaped base at the frond base, ovate-oblong, margins uneven or with rounded incisions, apex rounded at the tip, undersurface very sparsely covered with scales; scales like stipe scales, deltate to lanceolate, up to 1.5 mm long. Rhachis somewhat winged apically, not winged between widely spaced pinnae basally; scales like stipe scales, 4 mm long. Sori linear, 3-6 mm long becoming confluent at maturity, visible, exindusiate.
Notes: Untill recently this species was included within the broad concept for A. cordatum which in Zimbabwe was only found in Nyanga area. A. capense itself is restricted to South Africa, A. cordatum and A. phillipsianum occur in Zimbabwe.
Confusion possible with A. cordatum which has a more incised lamina, petiolate pinnae, a rhachis that is not winged and sori that are obscured by dense scale covering. A. capense can be distinguished from A. phillipsianum: A. capense has a rhachis that is only winged apically (throughout in A. phillipsianum), the pinnae are adnate apically & petiolate basally (adnate throughout in A. phillipsianum) and the sori are less long.
