Synopsis. — Frond both prostrate and erect. Prostrate frond creeping, 

 broadly linear, or membranous, with rhizoids, branching, without midrib or 

 nerves; margin toothed or laciniate. 



Erect frond stalked, flat, linear, occasionally with midrib, with flabellate 

 nerves; subdichotomously or subpalmately divided into numerous segments, 

 in some cases finely laciniate, frequently proliferating; margin entire, finely 

 serrate, crispate, or toothed; segments or branches in some cases broadly 

 obcuneate, in other cases narrow, becoming broadly linear, much prolonged 

 and flabellately expanded at apices or remaining linear. Stalk short, soon 

 merging into the frond, usually without midrib, but with flabellate, sometimes 

 anastomosing nerves extending into" the branches; or long, somewhat nar- 

 row and thickened, almost cylindrical, and again merging into the flabellately 

 nerved branches. Nerves not very conspicuous, usually extending through- 

 out the frond from base nearly to apex, becoming divided into flabellate, 

 frequently anastomosing veins, the latter soon evanescent. 



Sporangia in narrow lines flabellately disposed, occasionally confluent, on 

 upper segments of frond, or placed singly or in clusters along the margin, or 

 upon marginal sporophylls, the latter appearing at intervals or in a dense 

 fringe along the margin. Antheridia as yet unobserved. Cystocarps large, 

 projecting, irregularly disposed over both surfaces, or submarginal, or upon 

 marginal proliferations. 



Rem,arks on the Species. — The color of JV. violaceum 

 varies from a pale violet through bright violet red to purple 

 violet, in both the living and dried states. The plants attain
