Discussion
Subspecies alpina has a distribution in the Pacific Northwest similar to that of the type subspecies, although its geographical range extends to the Aleutian Islands. This subspecies shares most structural characters of subsp. macounii but it is generally a less robust plant, with narrower costae, longer awns, distal laminal cells, and peristome teeth, and shorter capsules. It differs largely in the overall appearance of the plants, which are usually distinctly glistening and more reddish, and the leaves are not crispate.
