mistaken for it. I examined dozens of plants of the latter species, but 

 did not meet with a single specimen of Cheilanthes. Still, in deference to 

 the opinions of others, 1 allow it to remain on the list.

Cheesem. (p. 964) gives A. fulvum as a native of Norfolk Island. 

 I did not see it. and do not know what is the evidence for its occurrence 

 there. 



28. Adiantum hispidulum Sw., M. 13. (^ A. pubescens Schk., E. 43.) 



Perhaps the most abundant species of the genus on the island. 

 Lord Howe, Kermadecs, New Caledonia. Australia. New Zealand, and 

 widelv in the Southern Hemisphere. 



29. Pteris tremula R. Br.. M. 18. E. 37. (= P. Kingiana Endl., E. 40; 



P. Baueriana Endl.. E. 40, according to Maiden.)

Anson's Bay : in forest. 



Kermadecs, Lord Howe. Australia. New Zealand, Polynesia. 



Forms from New Zealand, Lord Howe, the Kermadecs, and Norfolk 

 Island differ considerably in appearance, but can scarcely be separated 

 by any good characters. 



31. Pteris biaurita L. var. quadriaurita Retz., M. 20. (=(?) P. Trat- 



tinickiana Endl., E. 42.) 



Kermadecs, tropical and subtropical regions. 



32. Histiopteris incisa (Thbg.) J. Sm. (= Pteris brunoniana% Endl., 



E. 38 ; P. incisa Thbg., M. 21.) 



A large form ; is common on Mount Pitt. " Oak-fern " of the islanders. 

 Kermadecs, Lord Howe, New Caledonia, Australia, New Zealand, and 

 widely in tropical and subtropical regions. 



t This is marked in rny list as seen by me, but amongst scores of specimens of 

 Adiantum in my herbarium there is not one of this species, and I am now somewhat 

 doubtful of its existence on the island. 



J I have received additional specimens of Pteris from Norfolk Island, and am now 

 (March, tfii5) convinced that P. bnnioniana Endl. is a good species. [ shall probably 

 return to this in a subsequent paper.
