1 Flowers solitary or in corymbs of 2-4; pedicels not jointed just beneath the ovary or fruit, the fruit not disarticulating at maturity and thus the fruit shed with the entire pedicel; stems generally with (0-) 1-3 nodal spines and sometimes also with internodal bristles (especially on young, vigorous growth) (though these sometimes absent or nearly so in some species); [subgenus Grossularia, "gooseberries"]. | |
4 Calyx tube purplish or purplish-green; stamens 6-8 mm long; nodal spines 0-1 (-2) per node, 3-11 mm long, slender | |
6 Calyx lobes 2.5-4 mm long; stamens 1-2 mm long or 4-6 mm long | |
7 Fruit hispid; stamens 1-2 mm long; peduncles 7-25 mm long; pedicels 5-16 mm long; [of native habitats of the Mountains] | |
1 Flowers in racemes of 4-many; pedicels jointed just beneath the ovary or fruit, a portion of the pedicel thus remaining attached to the plant when mature fruits or aborted flowers are shed, the fruit disarticulating at maturity; stems lacking nodal spines and internodal bristles (except R. lacustre); [subgenus Ribes, "currants"]. | |
9 Stems lacking internodal bristles and nodal spines; racemes ascending to erect; fruit dark red when mature | |
9 Stems (especially young, vigorous growth) with internodal bristles and sometimes internodal spines; racemes spreading to drooping; fruit purple or black when mature | |
12 Pedicels 0.1-2 mm long, shorter than the lanceolate bracts (which are 3-10 mm long); fruits black when mature | |
12 Pedicels 2-8 mm long, about as long as the obovate bracts (which are 4-9 mm long); fruits black (rarely red, orange, brown, or yellow) when mature | |
13 Hypanthium narrowly tubular, 6-20 mm long; fruits black (rarely red, orange, brown, or yellow) when mature; sepals golden yellow | |
13 Hypanthium saucer-shaped, < 1 mm long; fruits bright red when mature; sepals brown, greenish brown, or greenish purple. | |
14 Pedicels glabrous; petals cream to pinkish; anther sacs separated by a connective as broad as the anther sacs; erect shrub [cultivated and sometimes persisting or escaping] | |
14 Pedicels stipitate-glandular; petals reddish purple; anther sacs almost adjacent, the connective much narrower than the sacs; declining or ascending shrub; [native] |
