The L. tenue of Blume does not appear to be more than a variety 

 of the present species.

(Lygodti Spec. Sclik. Hydroglossi Spec. Willd.) 



The single species on which Mr. J. Smith has founded the present 

 genus, is distinguished from true Lygodium by its reticulated vena- 

 tion, and by the petiole of the sterile pinnae being articulated. The 

 latter character we find to extend to the fertile pinnae also ; and the 

 articulation is not confined to this plant alone, but is very evident also 

 in several species having free veins, such as Lygodium articidatum, 

 A. Richard, and L. volubile, Swartz, &c. Therefore Lygodictyon, if re- 

 tained as a genus, must rest exclusively upon the reticulated venation.
