|discussion=<p>Plants of <i>Calliergon giganteum</i> frequently resemble miniature spruce trees because of dense and successively longer branches from the shoot apex downwards, regular radial branching, and somewhat spreading branch leaves. The branch leaves are often markedly narrower and more ovate than the stem leaves and may resemble those of <i>C. cordifolium</i> in shape and costa width, but their alar regions are more sharply delimited. The stem leaves are usually broadly ovate-cordate with a broad costa and large and sharply delimited alar regions. Plants with a characteristic pink hue are most frequent in exposed habitats of the North. Differences between this species, 1. <i>C. cordifolium</i>, and 4. <i>C. richardsonii</i> are discussed under the latter two.</p>
