niinating at the apex of the teeth-like segments, veinlets 

 six seven or eight pairs uniting and sending out a flexuose 

 vein which terminates at the sinuses of the teeth, sori 

 small on each veinlet in two lines close to the costules 

 forming transverse hands of brown dotted lines, involucres 

 cordato-reniform. (Tab. CCXLI. A.) — Klfs. En. Fil. 7;.

 — This is a striking Fern, with hirge pinna; spreading almost horizontally, and 

 these have a remarkably banded ajjpearance from the transverse lines of brown 

 sori, which though arranged in two lines one on each side of, but close to the 

 costule, yet in age unite as it were into one, and extend almost from one margin to 

 the opposite, but rarely are the small teeth or segments soriferous.
