Information
Stolons white, 0.3–1 mm diam., sparsely villous, hairs white, reddish brown, or purplish. Flowering stems erect, branching in distal 1/6–1/3(–1/2), (1.2–)3–21 cm, glabrous or sparsely villous, especially proximally, hairs white or reddish brown. Leaves alternate, membranous or fleshy. Stolon leaves: petiole 12–55 mm, usually sparsely villous, sometimes glabrous, hairs white or reddish brown; blade usually depressed-ovate to reniform, sometimes nearly round, 3–14 × 5–18 mm, base cordate, margins 5–7-crenate, not purple-spotted, glabrous or sparsely ciliate, hairs white, surfaces glabrous or sparsely villous adaxially, hairs usually white, rarely purple. Cauline leaves 1–3(–4); petiole (2–)4–20(–31) mm, glabrous or sparsely villous proximally, hairs white or reddish brown, sometimes purplish; blade depressed-ovate, flabellate, or reniform, 3–9 × 4–13 mm, base truncate to cuneate or cordate, margins 3–7-crenate, glabrous, surfaces glabrous. Inflorescences terminal, (2–)3–15-flowered, compact cymes; bracts green, usually purple-spotted, foliaceous, ovate to depressed-ovate or flabellate, 2–9 × 3–12 mm, margins subentire or 3–5-crenate. Pedicels absent or 0.1–1.5 mm. Flowers: hypanthium green or greenish yellow, usually not purple-spotted, rarely purple-spotted distally, turbinate to campanulate, 1–2.2 × 1.2–2.1 mm, glabrous; sepals usually erect, sometimes spreading, usually green, rarely yellow, usually purple-spotted throughout or distally, rarely not purple-spotted, ovate to broadly ovate or depressed-ovate, 0.8–1.5 × 0.8–1.7 mm, apex obtuse to rounded; nectary disc apparently absent; stamens (3–)4, 0.3–0.4 mm; anthers yellow, 0.1–0.3 × 0.1–0.3 mm; styles 0.2–0.3 mm. Seeds (6–)15–40, reddish brown, ovoid to ellipsoid, 0.5–0.8 mm, glabrous. 2n = 24.

Discussion
As treated here, Chrysosplenium tetrandrum 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 C. tetrandrum.
