78. Litobrochia undvlata. Moore, Card. Chron. 1867, p. 348, is a var. from 

 Viti, like the type, but with blunter ultimate segments with an undulated edge; 

 P. microptera, Mett. Kuhn, Linn. 36, p. 92, from Lord Howe's Island, comes 

 between the type and Endlicheriana ; L. areolata, Moore, Lowe New Ferns, 

 t. 57, seems to belong here.
