This quite accords in generic character with the original 
Hemionitis of Linnasus, and is the only known species of that 
genus, with quite undivided fronds. Indeed without the sori, 
and without observing the venation, this plant would pass 
for an Acrostichum of the Elaphoglossum group. Only 2 spe- 
cimens of it appear to have been preserved by Milne, and 
these are destitute of caudex: but in other respects they are 
very perfect. The veins are all connected just within the 
margin by a longitudinal vein as represented at our fig. 2.
