Flora of North America species comparison

appressed-hairy throughout (hairs becoming looser and ± ascending distally).

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

stipules translucent to pale green, appearing brownish upon drying;

petiole thickly, usually densely appressed-hairy throughout, rarely glabrous or sparsely hairy (on spring leaves);

blade reniform to orbiculate, 7–9-lobed, margins undulate, basal sinuses narrow, middle lobes equal to longer than their half-widths;

incisions absent;

teeth: sometimes proximal sides at least slightly connivent, slightly concave near apex, slightly asymmetric, apex subobtuse to acute, abaxial surface with nerves hairy throughout, internerve regions ± hairy throughout, adaxial light to grass green, sometimes glaucous, margins and folds usually turning reddish orange, sparsely to densely appressed-hairy throughout or only 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 densely appressed- to ascending-hairy;

peduncles appressed- to ascending-hairy or glabrous.

primary branches densely hairy;

peduncles sparsely hairy or glabrous.

glabrous or some of the proximal rarely sparsely hairy.

epicalyx bractlet lengths 0.5 times to almost equal to sepals (narrower);

hypanthium glabrous or sparsely appressed-hairy (on proximalmost flowers).
