Distribution
Newfoundland west to AK, south to NJ, MI, WI, MN, and Alberta. Also in northern Asia.
Morphology
Erect, unarmed shrub. Leaves palmately veined, glabrous to softly hairy below, with 3-5 lobes, the margins toothed, the two middle sinuses deeper than the others, the lateral leaf lobes directed forward. Flowers in drooping racemes, the sepals greenish-purple, to two 2 mm long; petals smaller, 1 mm, cuneate, truncate or notched; pedicels and axis of the inflorescence often with short-stipitate glands; hypanthium saucer-shaped above the ovary. Fruit red, smooth.
Notes
Flowers June to July
Wetland indicator: Obligate
Of the four Ribes spp. that I have identified in the field, this is the only one that has reddish flowers and a short hypanthium (floral cup). The Latin tristis means sad, perhaps a reference to the unkempt appearance of this shrub.
