I have seen no South African specimen, but the description 
and figure are from Ceylon specimens kindly forwarded to 
me from Kew.

Plate 94. Fig. 2. Nat. size, b Pinnule, magnified, c Barren pinna, 
nat. size. 
Crown tufted, stout, paleaceous, with linear brown scales, 
usually burned or withered off. Fronds ovate pointed, one inch 
broad, two to four inches long, on a stout stipe one to two inches 
long, and having four to six pairs of deltoid sub-opposite 
pinnae ; the lower the largest, half-inch broad, three-quarters 
to one inch long, shortly stalked, equal sided, erecto-patent, 
ascending and cut to the rachis into several lobed, trifid, or 
pinnatifid pinnules, having a shortly cuneate base, and wide 
attachment, or sometimes shortly stalked. Barren pinnae 
longer, thinly membranaceous, crenate. Rachises and stipe 
stout, brown, and shining, with scattered, small, stiff, brown, 
lanceolate, but not hair-like, scales, which are more abundant 
towards the base. Texture firmly herbaceous; frond glabrous 
on both surfaces ; indusium continuous, narrow, folding back 
early. Baker describes this as “ about midway between P. 
involuta and P. consobrina in cutting and general aspect.”
