Information
Plants terrestrial. Rhizome massive, erect to suberect, to 300 mm long, to 25 mm in diameter, set with roots, closely spaced stipe bases and hairs, hairs ferrugineus, acicular, pluricellular, uniseriate, to 6 mm long. Fronds crowded, caespitose, arching, to 6 per plant, to 2.2 m long; stipe proximally castaneus, stramineous to greenish higher up, adaxially shallowly sulcate, to 930 mm long, to 10 mm in diameter, initially densely set with hairs, hairs rigid, ferrugineus, pluricellular, uniseriate, apical cell acicular, to 10 mm long; lamina proximally anadromous, catadromous higher up, oblong-ovate to elliptic, basal pinnae reduced, 1-pinnate-pinnatifid, to 1.3 m long, to 700 mm wide, with up to 12 petiolated pinna pairs; rachis stramineous to greenish, adaxially shallowly sulcate, sulcus not confluent with that of the pinna-rachis, closely set with hairs similar to those on the stipe, to 3 mm long; pinnae petiolate, petiole to 4 mm long, alternate, overlapping, lanceolate to elliptic-acuminate, pinnatifid, incised to nearly the same depth from the apex to the base, to 430 mm long, to 200 mm wide; pinna-rachis stramineous, adaxially shallowly sulcate, pronounced abaxially, winged along the entire length, closely set with pale hairs similar to those on the rachis; segments adnate, narrowly lanceolate to oblong-acuminate, to 105 mm long, to 26 mm wide, lobed, lobes entire to crenate, to 14 mm long, to 7 mm wide, adaxially and abaxially set with acicular hairs along the veins and segment margins, pluricellular hairs, to 1 mm long. Venation catadromous or isodromous, evident, reticulate, secondary rachis, costal and costular areola elongate, rarely with a free included veinlet, free vein branches end in or near the margin. Sori semi-circular to lunate, confined to the segment and lobe sinuses, along a C-shaped near-marginal vascular commissure, to 3 mm in diameter; indusium a poorly modified reflexed margin, to 0.3 mm wide, entire; receptacle paraphysate, paraphyses simple, pluricellular, uniseriate, apical cell oblong to elliptic, to 0.4 mm long; sporangium long-stalked, simple, 3-seriate below the capsule, capsule globose to ovoid in lateral view, with (13-)14(-15) indurated annulus cells, epistomium (3-)4(-6)-celled, hypostomium (4-)5(-7)-celled. Spores 64 per sporangium, brown, ellipsoidal, monolete, echinate. Figure 27C & D.
Habitat
Ecology: Terrestrial, in leaf litter on seasonally moist evergreen forest floor, deeply shaded. Not edaphically bound, but in Swaziland it is restricted to soils derived from the Barberton sequence. Nanophanerophyte, mesophyte; fronds mesomorphic. Vegetative reproduction by the shortly branched rhizome. Seasonal pattern apparently pronounced with new growth restricted to the rainy season.
Range
Distribution: Rare in Swaziland and known from the north-western corner of the country only, occurring at an altitude of ±1 520 m. Widespread in sub-Saharan Africa and the western Indian Ocean region.
