|discussion=<p>Specimens of <i>Ranunculus pedatifidus</i> from southern Siberia, China, and central Asia, including the type specimen, are relatively small and slender, with all the main divisions of the leaf parted into narrow (1.5-2.5 mm wide) segments. American material, including the type of R. affinis, is more robust; the main divisions of the leaf are mostly undivided, and the ultimate segments are broader (2-4 mm). L. D. Benson (1954) referred all material from Asia and islands in the Bering Sea to var. pedatifidus. Other authors (P. N. Ovchinnikov 1970; E. Hultén 1968; A. I. Tolmatchew 1971), on the other hand, have limited typical <i>R. pedatifidus</i> to material from temperate Asia and have included material from northern Siberia in <i>R. pedatifidus</i> <i></i>subsp.<i> affinis</i>. T. G. Tutin and J. R. Akeroyd (1993) included both <i>R. pedatifidus</i> and R. affinis in Flora Europaea, but, as noted below (under <i>R. auricomus</i>), Tutin and Akeroyd's descriptions do not match the American plants. Further comparisons of American and Eurasian material are needed.</p><!--
--><p>Glabrous-fruited forms have been called <i>Ranunculus pedatifidus</i> var. leiocarpus (Trautvetter) Fernald; the variety was first described from Asia.</p>
