Pohlia bolanderi has glossy to whitish leaves. Glossy forms might be confused with P. longicolla, but P. bolanderi can be distinguished by its smaller size and dioicous inflorescences. The leaves of P. bolanderi are smaller and relatively broader than those of P. longicolla. Variety seriata is characterized by whitish, ranked leaves; it is not recognized here because of intermediate plants from western North America, although in their best development these plants are very distinctive. Plants of this variant might be confused with Conostomum tetragonum (Bartramiaceae).
