Discussion

Variety subjulaceum is frequent in the Alaskan Peninsula but uncommon (or unrecorded) elsewhere in North America; it is found mainly at high elevations in Europe. The variety has somewhat concave leaves. No sporophytes were found in North American material. The acutely attached branches, closely imbricate, straight leaves with sharp apices, and frequently excavate pigmented alar cells make this a distinctive variety.
