(yfappa, a line, alluding to the linear fructification.) 
PLATE OF GENERA, FIG. II. 
The three genera, Grammitis, Ceterach, and Scolopendrium, equally claim this 
plant ; the first, because the sori are linear and scattered, — the second, because 
they are concealed by scales, — and the third because they are between transverse 
veins; and as the scales which surround the Sori are whiter and more joined 
together than on other parts of the plant, they may be taken for covers, as sotne 
Botanists have considered them ; in this case the plant evidently belongs to the 
last genus.

Des. — Root perennial, fibrous, black, tufted. Fronds many from 
the same root, herbaceous, 3 to 6 inches high, blunt, of a thick 
texture, dark green above, covered with brown scales beneath. 
Lobes confluent at their base, round, entire, alternate at the lower 
part of the frond, flat only when young, afterwards curved inwards 
towards the main rib, thereby exposing more the fructification. 
Thecae all the summer, at first concealed by the scales, afterwards 
bursting through them in oblong, transverse masses, without covers, 
but surrounded by very delicate, white, membranous scales.
