course of the veins, and rising from them. This genus is an 
incongruous mixture of groups of plants, all connected by the 
nature of the sorus, but otherwise each group is more closely 
related to some indusiate genus, or to Polypodium, in which the 
sorus though ex-indusiate is round. These groups have been 
made genera by various authors, and in a natural classification 
must be separated ; but I follow Hooker and Baker in adopting 
the wider genus and the sub-genera used by them in “ Synopsis 
Filicum.”

Plate CXXIII. Natural size, small. 
Crown erect, stout, tufted, naked, but the undeveloped young 
fronds are clothed with green scales. Frond herbaceous, ovate- 
lanceolate, two-pinnatifid, villose in all parts, one to two feet long, 
three to six inches broad, with a stipe three to twelve inches long, 
which is villose with short deflexed hairs, and at first slightly 
paleaceous. Pinnae alternate, lanceolate, two to four inches long, 
one-half to three-quarter inch broad, the lower slightly reduced, 
all cut to near the mid-rib into oblong, obtuse, oblique, crenate
