Perennial herb from slender rhizomes, usually with stolons; stems erect, 3-20 cm tall, finely glandular-hairy, leafless or with a simple unstalked leaf near the base.
Basal leaves heart- to kidney-shaped, 1-3 cm long, doubly round-toothed, sparsely hairy, at least above, long-stalked; stem leaves, if present, reduced, unstalked, occurring near the stem-base.
Inflorescence a loosely flowered spike-like cluster of 3 to 12 flowers, blossoming upward, the flower stalks 2-6 mm long; petals greenish-yellow, about 4 mm long, the claw slender, the blades dissected into 8 linear, opposite segments; calyces broadly bell- to saucer-shaped, tubular portion joined to ovary; free hypanthium almost absent; calyx lobes 5, egg-shaped, blunt to pointed; stamens 10.
Capsules; seeds black, veiny-pitted.

Ecological Indicator Information

A shade-tolerant/intolerant, montane to subalpine, Asian and transcontinental North American forb (absent in the Pacific region). Occurs in continental boreal and cool temperate climates on fresh to moist, nitrogen-medium soils; its occurrence increases with increasing elevation and continentality. Sporadic in semi-open coniferous forests on water-shedding and water-receiving sites in the eastern coast-interior ecotone. Characteristic of continental forests.
