N. W. Montana: in the vicinity of Lake MacDonald, Flathead county, 
1000--2100™ alt. (J. M. Holzinger and J. B. Blake, 1898). 
The relationship of this moss is rather doubtful; it seems, however, to 
have some affinity with B. capitel/atum C. Mill. & Kindb., which it resembles 
in habit and form of the leaves, but it has more slender stems, the leaves 
somewhat decurrent, revolute in the lower part at least on one side, a looser 
areolation formed of much wider and softer cells with thinner walls, and a 
much broader nerve (100m wide at base, instead of 60), ending at a little 
distance below the apex.
