|discussion=<p><i>Hamatocaulis lapponicus</i> is rare in western parts of the flora area. The species is recognized by its large size (approximately as large as <i>Scorpidium scorpioides</i>), usually slightly plicate stem leaves without differentiated alar cells, and stem with neither central strand nor hyalodermis. Besides the larger size, <i>H. lapponicus</i> differs from <i>H. vernicosus</i> in its more or less patent stem leaf bases, and in stem leaves broadly ovate and more distinctly constricted at their insertion. <i>Hamatocaulis lapponicus</i> is usually more sparsely and irregularly branched than <i>H. vernicosus</i>, has somewhat less plicate leaves, and large parts of its shoots are more often red.</p>
