362 FLORA VITIENSIS. 
latis, pinnatis ; pinnis glabris, dimidiato-oblongis, obtusis, integris v. undulatis, basi supra truncato- 
auriculata, rachi pubescenti parallela ; venis furcatis ; ramis anterioribus, soriferis; soris rotundatis, 
indnsio reniformi-orbiculari integerrimo.—N. repens, Brack. U. $. Expl. Exped. Filices, p. 209.— 
Viti, Ovalau; on trees in mountain woods (M‘Gillivray! n. 1; U.S. Expl. Exped.). 
This species is nearly allied to JV. ramosa, T. Moore, Ind. Fil. p. 102 (Aspidium ramosum, Beauv. Flore 
d'Oware, p. 54. pl. xci.), but it can at once be distinguished by the truncated frond terminating in a single 
large pinna, so admirably shown in Beauvois’ figure. It is difficult to understand how it came to be con- 
founded with Nephrodium obliteratum, R. Br. Prodr., which is a completely different plant, though a true 
Nephrolepis (N. obliterata, Carr. ms.). The description of JV. obliterata, Hook. Sp. Fil. vol. iv. p. 154, is 
taken from JN. ramosa, T. Moore.

brevi, suberecto v. repente; frondibus simplicibus, pinnatifidis v. pinnatis.— Cyclosorus, Link, Fil.
