Cauline leaves 4-9; petiole absent or 0.1-4 mm, glabrous; blade ovate to depressed-ovate, round, or flabellate, 2.5-15 × 2-10(-20) mm, base attenuate to cordate, margins 5-7(-9)-crenate or -crenulate, glabrous, surfaces glabrous abaxially and adaxially. Inflorescences terminal or axillary solitary flowers or 2-10-flowered, open cymes; bracts green, not purple-spotted, foliaceous, ovate to flabellate, 2-7 × 2-7 mm, margins subentire or 5-7-crenate or -crenulate. Pedicels absent or 0.1-0.8 mm. Flowers: hypanthium green, not purple-spotted, turbinate, 0.9-1.8 × 1.4-2.6 mm, glabrous; sepals spreading to erect, green, greenish yellow, or greenish red, not purple-spotted or purplish brown-spotted distally, broadly triangular or broadly ovate to nearly round, 1.3-1.8 × 0.9-1.6 mm, apex obtuse to rounded; nectary disc conspicuous, green or purple, 8-lobed; stamens 4-8, 0.5-0.9 mm; anthers purple, red, or orange, 0.2-0.3 × 0.4-0.5 mm; styles 0.2-0.6 mm. Seeds 6-16, dark brown, spheroid to ovoid, (0.5-)0.6-0.8 mm, puberulent. 2n = 18, 24.

Flowering Mar-Jul. Marshy ground, streamsides, seeps, springs, swampy woods; 0-1500 m; N.B., N.S., Ont., P.E.I., Que.; Conn., Del., Ga., Ind., Maine, Md., Mass., Mich., Minn., N.H., N.J., N.Y., N.C., Ohio, R.I., S.C., Tenn., Vt., Va., W.Va., Wis.

Perennial herb 5 - 20 cm tall Stem: slender, branching, trailing along the ground but with ascending branch tips (decumbent). Leaves: opposite (lower leaves) and alternate (upper leaves), short-stalked, 5 - 15 mm long, egg-shaped to nearly round, non-toothed or irregularly toothed. Flowers: borne solitary at branch tips, 4 - 5 mm wide, lacking petals but having egg-shaped sepals that are greenish yellow to greenish red or green with brownish purple. The flower center has an eight-lobed disk that is red to brownish purple or green with eight short stamens attached between the lobes. Fruit: a many-seeded, two-lobed capsule splitting open across the top.

Similar species: Chrysosplenium americanum is unique to the Saxifragaceae species in the Chicago Region because its leaves and flowers are borne on the same stem and the flowers have eight stamens but lack petals.

Flowering: early April to early May

Habitat and ecology: This species prefers cool, shaded, springy or muddy soil, and is most commonly found in Barrien County along the Paw Paw River and occasionally found in the dune region.

Occurence in the Chicago region: native

Etymology: Chrysosplenium comes from the Greek words chrysos, meaning gold, and splen, meaning spleen, likely referring to supposed medicinal properties. Americanum means "from America."

From Flora of Indiana (1940) by Charles C. Deam

I found this species as a common plant in shaded woodland in cool, shallow water slowly moving through a depression in the woods, and also in adjacent pools of water in Porter County along the traction line north of Willis Stop. It has been reported from Lake, Marshall (Nieuwland reported it as found by Clark, but Clark did not report it in his list of plants in "Lake Maxinkuckee" by Evermann & Clark), Porter, and St. Joseph Counties. It is, no doubt, local in its distribution because of its peculiar habitat; however, since the plant is so inconspicuous, it may be more frequent than the reports indicate.
