GENUS XXVL—CRYPTOGRAMME. (i?. Br.) 
i^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.) 
I. 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-cuneate, deeply pinnatifid, those, of the 
fertile frond pod-shaped, -|-f inch long ; texture thickly herbaceous, 
both surfaces naked. B. Br. in Richardson^ s Appen. to Franklin^ s

(Also in Arctic and Alpine Europe, Asia, and North America.) 
GENUS XXVII.— PELL^A. {Link?) 
{Pellos^ dark co^.oured; 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 dearly visible; indusium broad.
