|discussion=<p>As treated here, <i>Chrysosplenium tetrandrum</i> is circumpolar. In North America, disjunct populations occur in subalpine and alpine habitats in the Bitterroot Range of Idaho and Montana, and in the Front Range of Colorado. Some specimens from northern Europe and the Russian Far East that have been referred to C. alternifolium appear to be morphologically indistinguishable from <i>C. tetrandrum</i>.</p>
