Flora of North America species comparison

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

densely spreading-hairy 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 to pale green proximally, apex green;

blade reniform or reniform-orbiculate, rather shallowly 7–9-lobed, margins flat or slightly undulate, basal sinuses wide or narrow, basal lobes not overlapping, middle lobes rounded, equal to longer than their half-width;

incisions usually relatively short, sometimes absent or relatively long;

teeth usually slightly connivent, mostly slightly asymmetric but a few strongly so, apex acute to subobtuse, surfaces densely pubescent throughout, adaxial gray green to dark green.

primary branches densely appressed- to ascending-hairy;

peduncles appressed- to ascending-hairy or glabrous.

primary branches densely hairy;

peduncles sparsely hairy or glabrous.

mostly glabrous or some of the proximal hairy.

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

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

green, often becoming reddish;

epicalyx bractlet lengths at least 0.5 times sepals (not longer, always narrower);
