Hemionitis lanoeolata, Hook. 
Stipite 8-10-pollicari crasso badio nitido, fronde subseque 
longa coriaceo-membranacea firma lato-lanceolata acumi- 
nata anguste marginata costata, costa valida subtus promi- 
nente fusca nitidissima, venis patentibus ubique anastomo- 
santlbus areolas oblongas bexagonas formantibus, venis 
omnibus soriferis.

This quite accords in generic character with the original 
Hemionitis of Linnagus, 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.
