 elevation. Its simple (undivided) fronds, Gin. to 

 Sin. long and ljin. to 2in. broad, are produced from 

 a wide- creeping rhizome densely clothed with rough, 

 dull brown scales, and borne on firm, erect stalks 

 3in. to Gin. long. They have their edges prettily 

 undulated, and are sharp-pointed at their summit, 

 while they are rounded or rather narrowed or 

 auricled at their base. The large and conspicuous 

 sori (spore masses) are disposed in a row. near the 

 midrib, and situated one between each main vein. Fig. 44 is reduced from
