Species Information

General:
Low, trailing perennial herb from a rhizome with a somewhat woody base; stems erect, solitary, simple, 5-25 cm tall, minutely hairy, greenish to reddish, leafless or with bracts on the lower part.
Leaves:
Evergreen more or less, 4-7 in a terminal whorl, oblong egg-shaped to diamond-shaped, short-stalked, 2-8 cm long, green above, whitish beneath, lateral veins arising from the midvein in the lower third of the leaf.
Flowers:
Inflorescence of a solitary, stalked, umbrella-shaped cluster subtended by 4 white to pinkish or purplish-tinged, broadly to narrowly egg-shaped bracts; petals 1-1.5 mm long, greenish-white with a purplish tinge.
Fruits:
Fleshy drupes, 6-8 mm long, bright coral red when mature, usually several.
Notes:
Hybrids between C. canadensis and C. suecica have been treated as either a variety of C. canadensis (var. intermedia Farr.) or as a separate species (C. unalaschkensis Ledeb.). The latter taxon is a common tetraploid with features between its parents.

Ecological Indicator Information

A shade-tolerant, sub montane to subalpine, Asian and transcontinental North American forb. Occurs in boreal and cool temperate climates. Scattered to plentiful in the mossy understory of coniferous forests on water-shedding and water-receiving sites, on nitrogen-poor soils. Often inhabits decaying wood, sides of large stumps and tree trunks, and topographic prominences in nutrient-poor wetlands. Oxylophytic species characteristic of Mor humus forms.
