THE FERNS OF SOUTH AFRICA 
below into a broad petiole, or adnate. Barren fronds are very 
thin, and with rounded decurrent lobes, and the margin is 
crenate even when fertile. Involucre very wide, of same 
texture as the frond, except the margin, which is scarious 
and undivided, or at least not regularly lobed. Baker re- 
marks: “differs from P. profuse d by its naked rachis and 
very broad indusium”; but it seems to me to be more nearly 
connected with the cut forms of P. auriculata Link. 
In Journal of Botany the indusium is described as crenate, 
but in Annals of Botany this is omitted. The specimens I 
have examined are neither crenate nor regularly lobed, as P. 
auriculata always is.

West. — At foot of Kamiesberg, Namaqualand, where it was discovered 
by Sir Henry Barkly, and again collected by Mr Bolus; Karree- 
bergen, 2000 ft (R. Schlechter, 8205). 
(In the Transvaal Mus. Herbarium is a specimen eight 
inches high from Piquimier’s Kloof (R. Schlechter, 4951) 
labelled P. lancifolia Baker, which has evidently been grown 
in shade and is young, the lobes rounded and sharply toothed ; 
it is an unusual form of Adiantopsis capensis (Thbg) Fee.)

Plate 92, Lower pinnae, nat. size, b Pinnule, magnified. 
Crown tufted, paleaceous. Fronds three to four-pinnate, 
deltoid, four to eighteen inches long and broad, on a naked, 
shining, brown, furrowed stipe, of equal length, paleaceous at 
the base. Pinnae deltoid, but with larger pinnae on the lower 
side; secondary pinnae also deltoid with larger pinnules on 
the lower side. Pinnules sessile, divided to near the rachis 
into two to five pairs of oblong or obtuse toothed lobes with 
a larger terminal one, or sometimes again pinnate and having 
lobed pinnules. Sori intramarginal, with a narrow mem- 
branous indusium. Pinnules narrowed when fertile, and not 
toothed as they are when barren. Whole frond glabrous, or
