POLYPODIACEiE. 123 



longer, firm, smooth, and nearly round, with a shallow groove in front, of 

 a dark brown colour at the base, upwards of a straw colour. Fronds 

 about a foot long, broad-ovate and pinnate, with from 6 to 8 small 

 obtuse lobules at base extending down to the stipe. Pinnce coria- 

 ceous, from 12 to 14 in number, 5 inches and upwards in length, and 

 from 8 to 10 lines broad, lance-linear, acuminate, adnate; inferior base 

 subauriculate and decurrent; the margin a little thickened, beautifully 

 and regularly punctate. Fertile pinnce long-linear, obtuse, with a 

 somewhat cartilaginous and lacerated indusium; the two lines of sori 

 becoming confluent. Veins immersed. 



This species very closely approaches the L. elongata of Blume ; but 

 his description is so short, that we cannot venture to refer our plant 

 to it.
