Sambucus williamsii was treated as a synonym of a highly variable, circumboreal S. racemosa Linnaeus by Bolli (Diss. Bot. 223: 187-197. 1994). The black fruit and dark green leaves (Bolli, loc. cit.) distinguish S. williamsii and S. melanocarpa A. Gray of W North America from other members of the S. racemosa complex. Sambucus williamsii also has a more pronounced fetid odor. Because of the high degree of variation and the pronouncement by Bolli (loc. cit.) that the variation within his circumscription of S. racemosa should be further evaluated in a geographic context through field, cytological, and biochemical methods, for the time being, we prefer to maintain S. williamsii, and, with less certainty, the following species, S. sibirica, as distinct.
