Flora of North America species comparison

glabrous or appressed-hairy proximally, glabrous distally.

usually densely spreading-hairy, sometimes sparsely in distal 1/2.

stipules translucent, usually suffused with red proximally, translucent to pale green distally, lobes pale green;

petiole glabrous or sparsely to densely appressed-hairy;

blade reniform-orbiculate, 7–9(–11)-lobed, margins flat or slightly undulate, basal sinuses narrow or wide, middle lobes as long as to longer than their half-widths, rounded to triangular-ovate;

incisions absent;

teeth ± connivent, slightly concave near apex, strongly asymmetric, apex subacute or obtuse, abaxial surface with nerves hairy throughout or in distal 1/2 only, internerve regions glabrous, adaxial glabrous or slightly hairy near margins, rarely (late-season leaves) hairy on folds.

stipules translucent, colorless proximally, lobes green, quickly turning brownish;

petiole thickly, densely pubescent (hairs patent or, when not fully developed, slightly ascending);

blade reniform to orbiculate, 7–11-lobed, margins flat or slightly undulate, basal sinuses wide, basal lobes not overlapping, middle lobes equal to longer than their half-widths and rounded, or as long as wide and straight-sided;

incisions usually absent, sometimes relatively short;

teeth sometimes proximal sides at least slightly connivent, side slightly concave near apex, usually slightly, sometimes markedly, asymmetric, apex acute to subobtuse, abaxial surface with nerves hairy throughout, internerve regions uniformly or irregularly hairy throughout, adaxial yellowish to light green, usually glabrous, rarely sparsely hairy on teeth, margins, and folds or on some folds only.

primary branches glabrous.
