mostly in size, and may be a shade grown form. It also resembles 
Cheilanthes capensis, but the indusium is quite continuous. 
41. Pell/ea robusta. Hk. 
Plate XXXIV. Fig. 3. Nat. size, b pinnule, magnified. 
Crown procumbent or shortly creeping, very stout, paleaceous, 
with rusty scales. Frond ovate oblong, bluntly pointed, glabrous, 
coriaceous, three-pinnate, one inch broad, two inches long, on a 
very stout, naked, channelled stipe, an inch long or more, with 
lanceolate red scales at the very base only. Pinnae six to eight 
pairs, close and overlapping ; the lower not larger than the upper 
side ; deltoid, with a distinct green rachis, bearing three to four 
pairs of pinnules, the upper cuneate three-lobed, and the lower 
divided to the mid-rib into five to seven ovate or three-lobed 
segments, which are one line long, and not more than a half line 
broad when single. Sori mostly confined to the triangular part of 
the lobes, continuous, comparatively broad, and almost meeting 
above ; same in texture as the frond. Kuhn makes this synony- 
mous with Pellasa deltoidea, but Baker maintains both species. 
Both are found only in Namaqualand, but the specimens I have 
seen are very distinct from one another and from everything else. 
Baker mentions its resemblance to the northern Cryptogramme 
crispa, Br., which, however, has the fertile and barren fronds 
different, while here they are alike. 
Pellsea robusta. Hk. Sp. 2, 147 ; Hk. and Bkr. S\n. Fil. 149. 
Cryptogramme robusta. Pappe and Rawson, 32. 
Allosorus robustus. Kunze, Linnsea. Vol. 10, 502. 
Between rocks near Goedeman’s Kraal, Namaqualand (Drege). 
Common throughout Namaqualand (Lady Barkly, Bolus). 
42 Pell^ea pectiniformis. Baker. 
Plate XXXV. Fig. 2. Natural size. 
Crown procumbent or shortly creeping, with abundant lanceo- 
late, reddish scales. Frond simply pinnate, six to twelve inches 
long, one to three inches broad, on a stout stipe four to six inches 
long, which is scaly at the base, and like the rigid rachis clothed
