Discussion

The typical form of the variety may have broadly ovate to broadly elliptic leaf blades 4.5–6 cm with 6–7 veins per side. With far more densely hairy parts than typical var. chrysocarpa and the indumentum persistent on the abaxial surfaces of the leaves, var. faxonii is an eastern counterpart of var. piperi, from which it differs in details of leaf.
