ture : the terminal one often bifid, or trifid, and those next to 

 it more or less decurrent; general length from 4 to 6 inches. 



Stipes from 6 to 12 inches long, round, and smooth. 



Fructification in a single line, of remote, large, round 

 spots, half-way between the margin and rib. 



Involucre not discovered. 



II. P, flagellijerum. R. Icon. Roxb. 14, t. 99. Aspidium 

 flagelliferum. R. Wall. Cat. p. 67, No. 2234. 



Shoots creeping under ground, stipes hairy ; fronds sub- 

 alternately pinnate, proliferous at top ; leaflets broad, ensi- 

 form, crenate, and crenulate, smooth. Fructifications in one 

 row, on each side, half-way between the nerve and margin. 

 Involucre reniform. 



Nat, of Bengal, Fructifying time the rainy season. 

 Root fibrous, and from the base of the stipes, where they 

 unite, spring many, very long, slender runners. 



Stipes a little woolly, particularly while young, and near 

 the base, dark chesnut colour, furrowed on the anterior 

 side ; whole length, frond included, from 2 to 3 feet. 



Fronds pinnate, terminating in an incurved, somewhat gem- 

 ma-like knob, which strikes root, and produces other plants 

 where it rests on the ground. 



Pinncs alternate, sessile, ensiform, with enlarged bases, 

 the lower pairs, (and they extend down to near the base of 

 the stipe,) broader, shorter, and sterile, with their margins 

 slightly serrate. The superior pairs fertile, longer, narrower, 

 and crenulate ; all are smooth on both sides. 



Fructifications in a single row of distinct dots on each side 

 of the nerve. 



Involucrum reniform. 



12. P, ferrugineum, R. 



Stipes and nerves clothed with much brown, scaly pubes- 

 cence ; fronds (S-5 feet high,) alternately pinnate; leaflets
