Society and Samoan Islands (U.S. Expl. Exped.). 2. D. Moorei, Hook., 2nd Cent. of Ferns, t. 53, from

Exped. Filiees, p. 245, from Tahiti (U. S. Expl. Exped.). 5. D. leptocarpa, Mett. Linnea, 1869, p. 143,

l. D. contigua, Sw. Syn. Fil. pp. 130, 339; frondibus coriaceis, czespitosis, subsessilibus, 
lineari-lanceolatis, profunde pinnatifidis ; segmentis linearibus, obtusis, apice dentatis, soriferis; in- 
dusio marginali, gibboso, a cuticula vix modificata formato.—Trichomanes contiguum, Forst. Prodr.

Exped.), Ovalau (M‘Gillivray!). Also from New Hebrides, Aneitum (M‘Gillivray !), Tahiti (Banks 
and Solander! D. Nelson! U.S. Expl. Exped.), Huahine (Capt. Cook, 1775 !), and Samoan Islands

2. D. pycnocarpa, Brack. U. S. Expl. Exped. Filices, p. 242, t. 35. figs. 1 and 2; rhizomate 
repente, crinito-paleaceo; stipitibus nudis, semiteretibus; frondibus coriaceis, glabris, late ovatis, 
acuminatis, quinatis v. pinnatis; pinnis suboppositis, lineari-lanceolatis, acuminatis, infimis bi- v. 
ternatis, sterilibus serratis, basi æquilateralibus acutis, fertilibus dentatis; venis simplicibus v. fur- 
catis, immersis; indusio tubuloso, apice truncato, submarginali.—D. pentaphylla, Brack. (non 
Blume), U. S. Expl. Exped. Filices, p. 241.—Matuku (M'Gillivray!), Ovalau, and Vanua Levu 
(U. S. Expl. Exped.). Also from Aneitum and Eromanga (M‘Gillivray !). 
This species is certainly different from D. pentaphylla, Blume, and may be distinguished at once by the 
greater number of the divisions of the frond, the bi- or ternate lower pinnæ, and the obvious veins. We 
can see no reason for separating the two forms described by Brackenridge as distinct. A large series 
collected by M‘Gillivray shows that the characters on which he depends are not constant.
