Adiantum lucidum, Swartz. 



Pteris lucida, Cayantlles.

 of this Fern in Sir William Hooker's "Species Filicum," we find 

 that a number of botanists have noticed the Adiantum obliquum 

 in its native habitats, amongst these, Bredemeyer, Sir B. H. 

 Schomburgk, Dr. Klotzsch, Le Prieur, B. Spruce, and L' Her- 

 monnier, all found it growing wild.

A native of the West Indies and South America, Porto Bico, 

 Caraccas, British Guiana, Columbia, Montague de Mahurie, 

 Cayenne, Tanaii, and Guadaloupe. 



An oblong pinnate frond, pinnae on short petioles, ovate-oblong, 

 acuminate, the margin on upper base truncate and parallel with 

 the rachis, the lower margin dimidiato-cuneate. 



Fronds glabrous, twelve inches long, upper surface dark green, 

 beneath glacous. 



Sori numerous, from fourteen to sixteen on a pinnule, oblong, 

 linear, extending along both the upper and lower margin to
