Our specimens are from a foot to a foot and a half long, 
with so much of the habit of A. Phyllitidis , that a casual 
inspection only would induce many Botanists to refer it to 
that species ; but a more careful examination will exhibit a 
difference in the broad and obtuse base of the pinnse, and 
a more remarkable one in the pinna? being here furnished with 
dichotomous free veins, whereas in A. phyllitidis they are 
reticulated, as in A. Ticeediana (Tab. 6.) 
Texas is the most northern limit we are yet acquainted 
with of this genus.
