Ribes lacustre (Pers.) Poir.
Common Name: SWAMP BLACK CURRANT
Coefficient of Conservatism: 6
Coefficient of Wetness: -3
Wetness Index: FACW
Physiognomy: Nt Shrub

In coniferous, mixed, or rarely deciduous forests, swamps, and thickets, often in dense shade, sometimes associated with rock outcrops. Usually easily recognized by the densely spiny glossy light brown young twigs, as well as the relatively deeply lobed leaves (sinuses ca. 2/3–3/4 of the way to the base of the blade). The flowers are reddish or yellowish and are quite flat or saucer-like, thus readily distinguishing them, even when fewer than five are present in a raceme, from the flowers of gooseberries, which have a clearly cylindrical or bell-shaped floral tube.
