IX, ©, 5 Copeland: Hawaiian Ferns 437 
Bureau of Science and in my own herbarium. These specimens 
go back to collectors as old as Gaudichaud, and include a con- 
siderable number collected and determined by Hillebrand him- 
self. Of recent collections, we have one sent in exchange by 
the Bishop Museum to the Bureau of Science; a collection made 
by H. M. Curran, then of the Forestry Bureau of this Govern- 
ment, during a visit to the Hawaiian Islands; a few specimens 
collected by Doctor Bartsch of the United States Bureau of 
Fisheries; a collection recently sent to me by the Hawaiian Board 
of Forestry, and determined at the same time as the Faurie 
collection; and the plants which I have been able to collect on 
two personal visits to the mountains near Honolulu. In the 
older collections, I have fortunately had an especially large rep- 
resentation of species of Asplenium, sent to me by the courtesy 
of the Royal Botanic Garden at Berlin. Another evidence of 
the quality of the Faurie collection is furnished by the fact, that, 
among all the other recent collections in my possession, there 
is only one fern, the assignment of which to an old and recognized 
- species is even doubtful. 
In this collection there appear three cosmopolitan ferns not 
hitherto collected in Hawaii. These are: 
ATHYRIUM ESCULENTUM (Retz.) Copel., Kauai. 
ADIANTUM CUNEATUM L. & F., Faurie No. 154, Kauai, Kealea. 
PTERIS LONGIFOLIA L., Faurie No. 45, Maui, Wailiku. 
The descriptions of the new species, and the other changes 
of name which seem to be called for, are as follows: 
ATHYRIUM MARGINALE (Hilleb.) Copel. comb. nov. 
Asplenium marginale Hilleb. Flora Hawaii (1888) 613. 
Diplazium, C. Chr. Index Filicum (1905) 235.

ATHYRIUM MAUIANUM Copel. sp. nov.
