Gen. 56. Vit taria, Sm.
Sori in continuous marginal or slightly intramarginal lines. A small genus,
almost entirely tropical, with fr e e mins and grass-like fro n d s o f subcoriaceous
texture. I t has considerable claim to be placed in the Involúcrale series near L in d saya.
The species are very difficult o f discrimination, and we have admitted here
tonsidcrably fewer than M. Fee, who has published an elaborate illustrated monograph
o f the genus, in which he relies to a large extent upon microscopic characters
(the shape o f the spores and abortive capsules) to characterize them. T ab. VI.
