* An error has crept into some modern books in regard to Notholena vellea, of R. Brown (* Prodromus, 
p. 146), from a supposition that he considered his plant to be the same as one brought by Masson 
from Madeira, and described as Acrostichwm vellewm, Ait. Hort. Kew. ed. 1. vol. iii. p. 457, and that he 
consequently adopted Aiton's trivial name when he placed it in his new genus. An examination of the 
* Prodromus’ proves that Mr. Brown had not then before him the Madeiran plant, which is obviously different 
from the Australian one; and, indeed, the diagnosis which he gives of his species excludes Masson's plant. 
The synonymy of the two species stands thus :—
