Discussion

Variety sylvaticum is a robust plant of the Pacific Northwest with stems to 14 cm high, sharply serrate leaves to as much as 19 mm, and large, plump, cylindric capsules, often ± zygomorphic. The type was collected by Menzies somewhere on the Northwest coast; Pogonatum macounii was collected in a ravine at 1370 m on Vancouver Island. Polytrichum alpinum var. campanulatum has large, ovoid-gibbous, almost horizontal capsules and is probably distinct, but its distribution is poorly understood.
