Podophyllum versipelle was treated by Shaw (in Stearn, Gen. Epimedium, 276-282. 2002) as comprising two subspecies: subsp. versipelle ("Leaf lobes elobulate, upper leaf with 4-7 lobes on one side, lobes shallow 1/5-1/3 of radius; inflorescence 4-9 flowered; pedicels with hairs") and subsp. boreale J. M. H. Shaw ("Leaf lobes often with lobules, upper leaf with 4 or 5 lobes on one side, lobes deep, 1/2-2/3 of radius; inflorescence 4-10(-19) flowered; pedicels glabrous or rarely hairy").
Within Podophyllum versipelle subsp. boreale, Shaw (loc. cit.) recognized two varieties: P. versipelle var. boreale (lobes of leaves with convex margins, lobes entire or trilobulate; pedicels and leaves abaxially glabrous) and P. versipelle var. sichuanense J. M. H. Shaw (lobes of leaves with concave margins, lobes usually trilobulate; pedicels and leaves abaxially hairy).
