"Adiantum obliquum. will rank next to 44. macrophyllum, figured at "TAB. 132 of this work, differ- 
ing, however, in its much smaller-sized, more obtuse and glaucous pinnz, and in the shape of the 
sori. Willdenow united it with the 244. jucidum of Swartz, though he seemed doubtful of the 
propriety of so doing; and Sprengel has, apparently with justice, separated them. 
It is probably not uncommon in the West Indies, whence we have received many specimens 
from the island of St. Vincent.
