indusio reniformi-orbiculari integerrimo.—N, repens, Brack. U.S. Expl. Exped. Filees, p. 209,— 
Viti, Ovalau; on trees in mountain woods (M‘Gillivray | n. 1; U.S, Expl. Exped.), 
This species is nearly allied to V, ramosa, T. Moore, Ind. Fil. p. 102 (Aspidium ramoswm, Beauv. Flore 
d’Oware, p. 54. pl. xei.), 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 deseription of JV. obliterata, Hook. Sp. Fil. vol. iv. p. 154, is 
taken from WV. ramosa, T, Moore, 
XXVIII. Nephrodium, Richard in Mich. Flor. Bor.-Amer. vol. ii. p. 266. Sporangia recep- 
taculo ex medio venularum imposita, in soros globosos compacta. Indusia reniformia. Vene 
pinnate, prominentes, yenulis simplicibus inferioribus conniventi-anastomosantibus.—Filices candice 
brevi, suberecto v. repente; frondibus simplicibus, pinnatifidis v. pinnatis.—Cyclosorus, Link, Fil, 
Sp. Pronephrium, Presl, Epim. Bot. p. 258.
