Stolons white, 0.3–1.2 mm diam., sparsely villous, hairs white or reddish brown. Flowering stems erect, branching in distal 1/6–1/3, 3–15 cm, glabrous. Leaves alternate, membranous. Stolon leaves: petiole 7–43 mm, sparsely villous, hairs white or reddish brown; blade depressed-ovate to reniform, 6–13 × 7–18 mm, base cordate, margins 5–9-crenate, not purple-spotted, glabrous or sparsely ciliate, hairs white, surfaces glabrous or sparsely villous, especially near petiole, hairs usually white, sometimes purplish.

Discussion
Iowa populations of Chrysosplenium iowense are widely disjunct from Canadian populations. The former are thought to represent Pleistocene relicts, isolated in the Driftless Area of northeastern Iowa and southeastern Minnesota. R. M. Weber (1979) studied the reproductive biology and ecology of the species in northeastern Iowa.
H. Hara (1957) treated Chrysosplenium iowense as synonymous with C. alternifolium Linnaeus var. sibiricum H. Hara. J. G. Packer (1963) recognized the close similarity between C. iowense and C. alternifolium var. sibiricum but maintained the two as distinct species in the absence of a modern, detailed analysis of the C. alternifolium complex. That approach is adopted here.
