Discussion

Ulota coarctata, a rather uncommon species, prefers climax beech-maple forests, and is distributed from Newfoundland south along the Appalachians to North Carolina and eastern Tennessee, westward in the Great Lakes region to Wisconsin. A disjunct specimen in northern Idaho (Leiberg s.n., US) is correctly identified, but the location needs to be verified. The obovoid capsules with strongly puckered mouth are diagnostic for this species. Ulota drummondii has football-shaped capsules, whereas U. crispa has oblong, 8-ribbed capsules constricted below the mouth. Additionally, U. coarctata has non-crisped leaves with clasping bases and acute apices.
