Inflorescence of usually 1-3 flowers in a drooping to spreading raceme much shorter than the leaves; flower stalks 1-3 mm long, not jointed below the flowers, glandular; petals whitish, egg-shaped, 2-3.5 mm long; hypanthium nearly cylindric to bell-shaped, 2-6 mm long; calyces pale greenish-white, glabrous to finely hairy; styles fused and soft-hairy to about midlength, about equaling the stamens.
Fruits:
Berries, round, reddish to deep-purplish blue, 1-1.2 cm long, glabrous.
Notes:
Three subspecies occur in BC:

1. Flowers mostly 8-11 mm long with sepals extended; leaves not glandular below.................. ssp. irriguum (Dougl.) Sinnott

1. Flowers about 7 mm long with sepals extended; leaves usually glandular short-hairy below

2. Hypanthium 5-6 mm long, not or only slightly flared; petals (2.5) 3.0-3.5 mm long; plants rare in SC BC...................... ssp. cognatum (Greene) Sinnott
