1 know of no specimens of this highly curious plant, but those 
which exist in Mr. Lambert’s herbarium, where they bear the 
valve is spread out, and becomes of an obovate figure. The three 
capsules which have scarcely risen above the surface of the frond, 
pate burst, have probably done so from the effect of pressure

I have derived: the name of this genus from joves one, and 
xAzi to shut up, from the circumstance of the single valve of

mannia, and the two of Targionia and Anthoceros, from which 
t genus it also differs in the want of a columella to which the 
seeds are attached.
