Discussion

Glandular individuals of Thalictrum amphibolum have been called T. revolutum var. glandulosior. They are seen throughout the range of the species and do not represent a distinct lineage. Occasional glandular plants with unusually short anthers are often misidentified as T. pubescens.

Material of this species from the western United States has been incorrectly assumed by previous authors to be Thalictrum dasycarpum, because T. amphibolum is not included in floras of that region.

The name Thalictrum revolutum de Candolle, used for this species in the printed version, FNA vol. 3: 269 (1997), is an illegitimate superfluous name that pertains to T. pubescens Pursh but has been misapplied to T. amphibolum.
