it must be confessed that this species comes very near to 
N. seductriz ; but its much larger size, longer fruitstalk and 
operculum, together with the broader, more evidently acuminated 
and entirely nerveless leaves, have induced me to keep it distinct. 
With N. cladorrhizans in point of size it has a greater resem- 
blance: but that plant has its leaves, though likewise destitute 
of nerve, of a different shape, not very correctly represented in 
Hedw. Sp. Muse., and the “rami apice radicantes” are never 
found on the present species.
