We are unwilling to lose the opportunity of figuring this beau- 
tiful plant, which was first made a Mniwm and then a Bryum 
by the excellent Swartz; and afterwards was considered by Schwae- 
grichen as a synonym to Bartramia arcuata, from which the 
great length of the footstalk, its erect (never curved) direction, 
and the decidedly sulcated capsule will always keep it distinct.
