was based, with certain species of Baissea, and consequently transferred it to this genus. 
In this I concur entirely with him. He maintains the other species of Zygodia, 
of which he saw only Z. urceolata, in the genus Zygodia; but, even with this 
emendation the two genera are not perfectly homogeneous. I have indicated this 
by dividing each of them into two sections, viz., Eubaissea and Guerkea, and Euzy- 
godia and Hualla. They are in so far parallel sections, as Eubaissea and Hualla 
possess supra-staminal scales, though of a somewhat different disposition, whilst 
Guerkea and Euzygodia lave none. I do not consider myself justified to go 
beyond this, as we know these plants very imperfectly, each of the species of 
Zygodia, for instance, being known only from a single collection and mostly a single 
specimen.
