The tips of some short, lateral shoots of wild black currant produce clusters (racemes) of 6-15 flowers that are suspended by short pedicels from a central, drooping stalk 1-3" long. At the base of each pedicel is a 3/8" long yellowish bract. Individual flowers are 1/2" long, bell-shaped with a short tubular calyx with (1) five spreading, oblong, greenish-white apical lobes (sepals), (2) five squared-off whitish petals emerging from the tubular calyx and forming a ring-shaped wall, (3) five stamens, shorter than the petals, with cream-colored anthers, and (4) a green ovary with two styles that are fused except at their tips. The fruit consists of 3/8" wide, shiny berries, initially green, black when fully ripe, containing lots of tiny seeds. The berries are edible when cooked and have been used to make pies, jelly, or wines (if you can get to them before the birds do). Note that commercial black currants are derived from the European version of this species (Ribes nigrum), not Ribes americanum.

Golden currant produces one- to three-inch-long clusters (racemes) of 5-18 drooping flowers from the leaf axils. Individual flowers are 3/4" long and across; the joined sepals are yellowish-green and tubular basally but abruptly flare into five bright golden-yellow, rectangular lobes with rounded tips. The petals are short (2-3 mm), rectangular structures that surround the throat of the corolla; they may be yellow or orange but are usually red or red-tipped. Between the petals are five stamens that extend to the tips of the petals, bearing white anthers; the styles are light green, fused to just below the stigmas, and protrude beyond the petals. The fruit is a small (1/4-3/8") edible berry with lots of seeds; fruit color is initially green but ranges from golden yellow to black when mature. Unlike gooseberries, this plant lacks spines and prickles; its large yellow flowers are distinctive. Golden currant is native to North America and was once very popular as an ornamental plant (and fruit for jams and jellies); it has probably escaped cultivation numerous times.

Missouri gooseberry produces groups (racemes or corymbs) of 1-3 flowers on a horizontal flower stalk near some leaf petioles; the 1/4-1/2" long flower pedicels droop downward, so the axis of the flower is vertical. An egg-shaped, sessile bract is present at the base of each flower stalk. Missouri gooseberry flowers are easy to overlook because they don't comport with one's usual idea of "flowers" — they are very elongate, as if viewed in a fun house mirror. The flowers have a very narrow, white or greenish-white, tubular calyx with 4-5 oblong, spreading or reflected sepal lobes as long as the calyx; five short, erect petals extending from the calyx; and 4-5 stamens that double the vertical length of the flower. Hidden inside, at the base of the calyx, is a smooth ovary topped by a single pistil with one style; only the style is visible externally, sometimes extending past the stamens during flowering. After fertilization, the flower parts wither and the ovary expands into a smooth, globular berry 6-12 mm in diameter containing numerous tiny seeds; the berry is initially green, turning dull red or dull purple when ripe. If you see a gooseberry in Jackson Park with a prickly surface on the fruit (looking like a miniature, green medieval mace), it is prickly gooseberry, Ribes cynosbati, which also has lobed leaves. I have yet to see prickly gooseberry in Jackson Park, but it is known to occur in northern Illinois.
