refers, Bedd.F. B. I. t. 21, but it was taken from muitisecta; the two 

 varieties, however, differ very slightly, if at all. 



GENUS XXVI.— CRYPTOGRAMME. (R. Br.) 



{Kryptos, hidden ; gramme, a line.) 



Sterile and fertile fronds usually different from the same root ; 

 sori terminal on the veins, at first separate, subglobose, afterwards 

 confluent, the continuous indusium formed of the changed margin 

 of the frond, rolled over them till full maturity. (Differs from Pellaea 

 rather in the dimorphic fronds than in anything else.) 



1. Cryptogramme crispa. (R. Br.) Glabrous, tufted, scales 

 at base of stipe, lanceolate, acute, pale-brown ; fronds 2-4 inches 

 long, i|— 2 inches broad, oblong, 3-4-pinnatifid ; ultimate segments of 

 the barren frond obovate-cxmeate, deeply pinnatifid, those of the 

 fertile frond pod-shaped, \-% inch long-; texture thickly herbaceous, 

 both surfaces naked, R. Br. in Richardson 's Appen. to Franklin's 

 \st Journal, p. 54. Hook. Syn. Fil. p. 144. C. Brunoniana (Wall.), 

 Bedd. F. B. I. t. 164. Allosorus crispus, Bernh. 



Himalayas, Kumaon to Kashmir, 10,000-15,000 feet; Sikkim, 

 10,000-14,000 feet, head of Lachen Valley. 



(Also in Arctic and Alpine Europe, Asia, and North America.) 



GENUS XXVIL— PELL^EA. (Link.) 



(Pellos, dark coloured, the colour of the fronds.) 



Sori intramarginal, terminal on the veins, at first dot-like or 

 decurrent on the veins, but soon running into a line ; involucre or 

 indusium formed of the more or less changed edge of the frond, 

 quite continuous, sometimes very narrow ; veins free. (Differs from 

 Cheilanthes in the continuous indusium.) 



§ Veins clearly visible ; indusium broad.
