128 POLYPODIUM FORTUNI. 



ceolate, attenuated both at the base and apex, subcoriaceous in 

 texture, slightly wavy or undulated, and with the margins some- 

 what recurved, entire or subsinnate on the margin, smooth, 

 punctulate, with small transparent dots. 



Length of frond about twelve inches; colour bright green. 



The sori round, prominent, uniserial near the costa, and 

 formed on the upper part of the frond. 



Rhizoma creeping, scaly, and slender, with the fronds lateral 

 and articulated. 



The transparent dots in the fronds indicate the thickened 

 apices of the short free veins (veinlets) which branch out from 

 the sides of the series of net-work meshes in which the larger 

 veins are united. 



For plants of this species I am indebted to Mr. Sim, of 

 Foot's Cray; and for fronds to Mr. Henderson, of Wentworth. 



It does not yet appear in any of the Nurserymen's catalogues, 

 excepting Mr. Sim, of Foot's Cray. 



The illustration is from a frond kindly forwarded by Mr. 

 Henderson, of Wentworth.
