This quite accords in generic character with the original 

 Hemionitis of Linneeus, 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 Acrostichurn 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.
