Description: The base and apex of one leaf are broken. The 

 petiole of the other one is wanting and the apex is bent a little, which 

 gives it somewhat the appearance of being emarginate, as are the 

 leaves of Leguminosiics hymenophyllns, which, indeed, the specimen 

 resembles. The leaves are oblong or elliptical, narrowed to the base 

 and apex, entire. Only a few of the secondaries can be indistinctly 

 seen. They are joined to the midvein at an angle of about 45°. They 

 curve in passing to the borders and are camptodrome. The midrib 

 is heavy at the base, but tapers rapidly, becoming very thin toward 

 the apex.
