The species embraced under this genus agree in habit and venation 

 with Lindscea, but have the sori interrupted, on account of the upper 

 margin of the pinnae being lobed, serrated, or crenate-toothed ; each 

 lobe or tooth bearing near its base a solitary sorus seated on the apex 

 of a single vein, or rarely on the combined apices of two adjoining 

 veins, as sometimes happens in the 0. pulchellum of J. Smith. The 

 special indusium is membranaceous, and rounded, or very slightly 

 reniform.

The figure cited represents the lower and middle portion of a frond, 

 and a magnified pinna: the pinnae in our plant, though otherwise 

 similar, are seated on a petiole a little longer than there represented.
