|discussion=<p>Much variation in Thalictrum macrostylum seems to be associated with habitat differences, especially the amount of sunlight received. The name T. subrotundum merely represents plants of T. macrostylum growing in deep shade. Common garden studies and cluster analyses do not support recognition of two species (M. Park 1992).</p>
