general habit, in texture of the frond, in the double calyx, and in the male fructification arising 
from beneath the perigonial scales ; but it is removed from it by the different substance of the 
nerve, by the more deeply-divided outer calyx, by the shortness of the Corolla, and by the differently- 
shaped, and distantly-placed, perigonial scales. I have received several Jungermanniae, both from 
the East and West Indies, which agree in general habit with both these, and which will probably 
be found to have the same fructification.
