262 THE FERNS OF LORD HOWE ISLAND. 



longae et 15 cm. latae, virides, breviter acuminatae, rhachidibus et 

 costis in superiore latere dense tomentosis, siibtus muricatis, pune- 

 tis cum apice rotundo brunneo nitenti; pinnulae creberrimae, ad 

 10-12 cm. longae et 1-1-25 cm. latae, in pinnulas sessiles, falcatas 

 divisae; pinnulis ii. integris vel crenulatis, pinnato-nervatis, mar- 

 g'inibus recurvis ; sori 10-12 in singulis pinnulis ii. ; color laete-viri- 

 dis, subtus subcaeruleus, siccitate fuscescens; textura firma sub- 

 eoriacea. 



This fern is easily distinguished from all its congeners, even by 

 the bluntish pinnae; the swollen base of the stipes is quite distinc- 

 tive; it could only have been referred to ^1. australis through the 

 insufficiency of the specimens available.
