|discussion=<p><i>Potamogeton pusillus </i>subsp.<i> pusillus</i> is nearly worldwide. When it is in fruit, the inflorescence is interrupted. That character combined with its narrow, linear, 1–3-veined leaves makes this taxon easily recognized. The nodal glands are green, essentially the color of the stems. Often appearing only as bumps on the stem at the nodes, they are difficult to see. Also, because the glands frequently occur at only a few nodes per plant, one can easily overlook them.</p>
