Distinguishing features of Meesia uliginosa include the ligulate leaves and strongly revolute leaf margins. The leaves are erect when dry or moist, and the costa is quite strong. The setae are generally much shorter than those of either M. longiseta or M. triquetra. Although M. uliginosa typically has obtuse leaf apices, some arctic populations have somewhat acute leaf apices; these have typical M. uliginosa costal anatomy.
