122 BIOGRAPHICAL SKETCH OF THE 
It had been Mr. Cunningham’s intention, when he re- 
turned from Norfolk Island, to have gone on a botanical 
excursion to Swan River; but the lengthened period he 
was detained at that island, and the very little communi-

This fern belongs to a section of Nephrodium extremely difficult to de- 
termine specifically, but the character of the lower pinne being so yay 
distant, (3 to 4 inches,) and their nearly triangular form will distinguish 
it from its congeners. Found also at Timor, 1819.

This fern, which I apprehend is the same that Endlicher has taken up 
as Stegania lanceolata, R. Br. is very distinct from the Van Dieman's 
Mauritius, but that fern has not the semi-orbicular lacinis of the 
Norfolk Island plant. :
