Swamp Red Currant - Ribes triste
State Rank Reason (see State Rank above)
Rare in Montana, where it is known from a few collections from the western portion of the state. Additional data are needed.
Swamp Red Currant is a shrub that is up to 1 m tall. It has unarmed spreading to nearly prostrate, straw-colored stems that are glabrous to sparsely hairy and glandular. The alternate leaves have petioles and broadly spade-shaped blades, which are up to 10 cm wide and resemble a maple leaf. Leaves are glabrous above but sparsely hairy below. 6-13 short-stalked flowers are borne in pendant, open, spike-like inflorescences in the leaf axils. The flowers have a glabrous, saucer-shaped, purple or purple-spotted, 5-lobed calyx that is 2-3 mm long and 5 reddish-purple petals that are ca. 1 mm long. The 5 stamens are ca. as long as the petals, and the 2 glabrous styles are united below midlength. The ovary is attached inside the base of the calyx and matures into an egg-shaped, glabrous, bright red berry that is less than 1 cm long.
Flowering in July.
There are many species of Ribes; a technical manual and hand lens are required for positive identification. Ribes hudsonianum, the other native species with unarmed stems and saucer-shaped flowers, has a glandular calyx.
