Synonyms: Allosorus capensis (Thunb.) Pappe & Rawson
Allosorus coriifolius (Kunze) Pappe & Rawson
Pteridium aquilinum (L.) Kuhn var. lanuginosum (Willd.) Kuhn
Pteris capensis Thunb.
Pteris coriifolia Kunze
Common names: Bracken (English) Rugombwe (Shona) Uhombwe (Shona)
Frequency: Locally abundant
Status: Native
Description:
Rhizome widely creeping, subterranean, 5-10 mm in diameter; scales brown, very fine, up to 1 mm long. Fronds widely spaced, stiff, hard, erect, pubescent fronds, 0.5-1.75 m tall, often forming large, dominant colonies in suitable habitats. Stipe up to 0.5 m long, underground portion swollen and covered with fine, brown hairs, above-ground portion pale-green, glabrous. Lamina 3-pinnatifid to 4-pinnate, triangular in outline. Pinnae standing out from the rhachis horizontally at nearly right angles; basal pinnae half as long as the frond; pinnae in the upper half 3-pinnatifid. Pinnules deeply incised, joined to the costules, with apices that are not long and narrow. Sori linear, continuous, situated just inside the inrolled margins; pseudo-indusium continuous.
Notes: The rhizomes of this fern are fire resistant and after periods of frost or drought, the dried, brittle fronds may persist for some time. New fronds will develop soon after the start of the rains, showing the typical "fiddleheads" of the unfolding fronds. It forms extensive colonies.
Derivation of specific name: aquilinum: of an eagle; either because the spreading pinnae resemble the wings of an aegle or a reference to the shape of the vascular bundle in the stipe.
capense: of the Cape
Habitat: In open scrub, forest edges, confined to high rainfall areas.
Altitude range: (metres) Up to 2400 m
Worldwide distribution: This subspecies is widespread in tropical Africa & South Africa, also in Madagascar, Mauritius and RĂ©union. The species as a whole is one of the most cosmopolitan fern species.
