The Ferns of South Africa. 
40. Pellaea leltoidea. Bkr. 
Plate XXXIV. Fig. 1. Nat. size. Fig. 2, var. laxa, nat. size. 
Crown tufted, abundantly set with rusty red scales. Frond 
widely deltoid, subcoriaceous, glabrous, distinctly bi-pinnate ; 
pinnae about three pairs, with lobed or pinnatifid pinnules, or the 
large lower ones on the lower side of the lower pinnae again pinnate. 
Frond one to one and a half inches long, one and a half to two 
inches broad, each lower pinna about as large as the rest of the 
frond above them, but much larger on the lower side than on the 
upper. Segments oblique, three lines long, one to two lines 
broad, bluntly triangular from about halfway down, below which 
they are narrow T ed with a curve into a broad base ; the triangular 
part fertile, with a continuous, rather narrow indusium of the same 
texture as the frond, but having a thinner, scarious lobed margin. 
Stipe and rachis nearly black, naked, shining ; rachis slightly 
margined. Not unlike P. geraniaefolia, but distinctly pinnate 
throughout. 
Pellaea deltoidea. Bkr. Syn. Fil. 146. 
Cheilanthes deltoidea. Kze. Linnaea, 10,535 ; Hk. Sp. II. 106, 147 ; 
Pappe and Rawson, 36 ; Kuhn, Fil. Afr. 70. 
Kuhn also gives as a synonym to this species Pellaea robusta, 
FLk., which I have maintained as a separate species. 
Little Namaqualand only ; growing among fissures of the 
rocks near Silver Fontein (Drege), and collected since by Rev. 
Mr. Whitehead, and more recently by Sir H. Barkly. 
Cape Colony, Burchell, 2033 (“ Syn. Fil.’’). 
Var. laxa, mihi (Plate XXXIV., 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 oppo- 
site, 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 C. deltoidea
