|discussion=<p>Glandular individuals of Thalictrum revolutum have been called 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.</p><!--
--><p>Material of this species from the western United States has been incorrectly assumed by previous authors to be T. dasycarpum, because T. revolutum is not included in floras of that region.</p>
