DESCRIPTIONS OF THE SPECIES 
217 
Stipe and rachis nearly black, naked, shining ; rachis slightly 
margined. Not unlike P. concolor , but distinctly pinnate 
throughout.

Ind. 244. 
Pellaea deltoidea. Bkr. Syn. Fil. 146; Sim, Ferns of S. Afr ., 1st ed., 94. 
Cheilanthes deltoidea. Kze, Linnaea , 10, 535 ; Hk. Sp. 2, 106, 147 ; 
Pappe and Rawson, 36; Kuhn, Fil. Afr. 70. 
Kuhn also gives as a synonym to this species Pellaea 
robusta Hk., which I have maintained as a separate species. 
West. — Little Namaqualand only; growing among fissures of the 
rocks near Silver Fontein (Drege); and collected there since by 
Rev. Mr Whitehead, and more recently by Sir H. Barkly; Lange 
Kloof, 400 ft (R. Schl. 8039); Hopefield, 150 ft (R. Schl. 5333); 
crevices between Dabaigabis and Griindoven, 4200 ft (Dr H. H. W. 
Pearson, 3176). 
Cape Colony. — (Burchell, 2033, Syn. Fil.). 
Var. LAXA, Sim (Plate 105, Fig. 2), much larger than the 
type ; crown tufted, set with red lanceolate scales. Fronds 
quite deltoid, three inches long and broad, with two pairs of 
opposite, one-sided, deltoid pinnae, and a short terminal pinna, 
and with a naked, shining, brown stipe, three to five inches 
long. Pinnules similar to those of the type, but larger in all 
parts, more rounded, and with a distinctly cuneate, almost 
stalked base. Texture thinly herbaceous ; indusium narrow. 
Collected by Mr Bolus in Namaqualand in 1883. It differs 
from D. deltoidea mostly in size, and may be a shade-grown 
form. It also resembles Adiantopsis capensis , but the indusium 
is quite continuous.
