572 RoBINSON: PTERIDOPHYTA OF THE HAWAIIAN ISLANDS 
Fil. U. S. Expl. Exp. 71. 1854). However, his specimens in the 
U.S. National Herbarium at Washington do not correspond with 
Kaulfuss’s description of A. aemulum in dimensions or in other 
characters. The series of specimens noted above seems to repre- 
sent but one species as indicated by the texture, uniform punctua- 
tions, and revolute margins of the leaves, and by the oblong- 
lanceolate scales of the rhizome. The dimensions of the leaves 
are fairly constant with the exception of a few plants, as Baldwin 
98 and Wilkes Expedition, Hawaii, District of Puna, which are 
smaller than the others.
