Discussion

Bartramia subulata, limited in the flora area to the high mountains of Colorado, is a diminutive species with erect, symmetric capsules that might be mistaken for B. stricta. The latter species, however, has a well-developed exostome, the leaf base is not sheathing, and shoulders are absent or, at best, weakly developed.
