Africa and African Islands ; growing in deep shady ravines. 
Kaff. — Omzamcaba (Drege). 
Natal. — Abundant at Umpumulo, 2000 to 3000 feet (Buch.), Inanda, 
Maritzburg, and midland districts (Wood).

Plate LXXXI1. Natural size. 
Crown erect, tufted. Frond herbaceous, glabrous, widely 
lanceolate, one to two feet long, three to six inches broad, with a 
green, herbaceous, flattened, glabrous rachis, and a naked, 
channelled stipe, six inches long. Frond proliferous below the 
terminal pinnule. Pinnae twenty to thirty pairs, one and a half to 
two and a half inches long, one-half to three-quarter-inch broad at 
the base, and tapering to a rather blunt point, cut uniformly to the 
broadly winged mid-rib into eight to twelve pairs of regular, close, 
bluntly oblong, simple pinnules, one line broad, one to three lines 
long ; the lower pinnule on the upper side broader, sub-flabellate, 
2-3-4-fid, or pinnatifid. Sori oblong on the upper side of the vein 
but not marginal ; mid-rib together with its wings one line broad. 
Pinnae longest at the middle of the frond. Baker suggests that it 
may be a Dareoid form of A. erectum, while Pappe and Rawson 
and Wood remark on its growing in company with A. Dregeanum, 
to which it is closely related. Kunze mentions a form with 
falcate pinnae.
