THE FERNS OF SOUTH AFRICA 
rachis, and mid-ribs set with soft, spreading, hair-like, yellow- 
ish scales, very abundant below. Pinnae one to one and a 
half inches long, plain, deltoid, hardly equal-sided, cut to or 
near the rachis into entire oblong lobes, having a broad 
attachment, or the lower ones pinnatifid with one to four 
pairs of lobes ; upper pinnae less divided, more or less con- 
fluent. Texture firmly herbaceous; pinnae glabrous on both 
surfaces, and edged by the narrow, white, membranous, in- 
tramarginal, and early reflexed, entire, but often undulated 
indusium. I cannot distinguish from this the Natal specimens 
in which the scales of the stipe are adpressed, more rigid, and 
brown, and the pinnules rounded at the base or almost stalked. 
These are the P. Bojeri of Buchanan’s List and of Wood’s 
Natal Ferns , but Christensen places P. Bojeri Hk. under P. 
qnadripinnata. 
This is a badly understood and most confusing plant. 
I find difficulty in drawing a line between it and P. viridis , 
var. glauca. Buchanan found the same difficulty, while Lady 
Barkly and Pappe and Rawson included both here, and the 
Graaffreinet specimens identified as this at Kew approach 
var. glauca very closely. The paleaceous stipe and rachis, 
less divided, less triangular, and more plain frond, characterise 
this plant, which appears to be rather rare though widely 
spread. The connection with P. qnadripinnata is much more 
distant, but P. namaquensis is very close.
