of the upper part of what appears to have been a very large quadri- 

 pinnate frond. This has a slightly striated surface; the ultimate 

 pinnules are incisely serrate, with sori seated in the apices of the inci- 

 sions, between two unequal teeth.

 Var. (3. Ovolau, Feejee Islands. 



Plant terrestrial ; the rhizoma short and thick ; the fronds tufted. 

 It abounds at the Sandwich Islands, inhabiting, as on other islands in 

 the Pacific, low savannas and open places on the declivities of the 

 minor ranges of mountains. In our variety (3. the ultimate divisions 

 are twice the breadth of the usual form; in both, it frequently 

 happens that two venules unite at the base of the indusium, thereby 

 forming an elongated areole. May not our variety be the D. cuneir- 

 formis of Swartz ?

This handsome species is well described by Sir William Hooker 

 in his Species Filicum. But among our specimens we find one or 

 two in which the rhachis and costa of the ultimate divisions are more 

 compressed than in the usual form of the species, and these bear 

 small proliferous buds on the upper surface, while a few scattered
