|discussion=<p><i>Pohlia filum</i> is an easily recognized species characterized by erect, somewhat glossy leaves, and ovoid gemmae that normally arise singly in the leaf axils. The gemmae have a few small, triangular, rather stiff leaf primordia at the apex, rarely with one or two primordia proximal on the gemma body. The gemmae of <i>P. drummondii</i> are more elongate-cylindric and branchlike, with larger, flexuose, often green leaf primordia at the apex and also frequently more proximally on the gemma body.</p>
