Flora of North America species comparison

densely spreading- to slightly reflexed-pubescent or only sparsely so in distal 1/2.

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

stipules translucent, sometimes wine red-tinged proximally, lobes green;

petiole sparsely to densely spreading- to reflexed-hairy;

blade reniform to orbiculate, 7–9-lobed, margins strongly plicate to undulate, basal sinuses closed, basal lobes overlapping (in plants from spring-flooded habitats, only cauline leaves with wide sinus may persist), middle lobes usually longer than their half-widths, as long as wide, longer than wide (with ± straight sides);

incisions absent;

teeth: proximal sides connivent or slightly so, sometimes slightly concave near apex, slightly to strongly asymmetric, apex subobtuse to obtuse, abaxial surface grass green to dark green, nerves hairy throughout, internerve regions irregularly or uniformly hairy, adaxial densely spreading-hairy throughout or only on margins and folds.

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.

primary branches sparsely to densely hairy;

peduncles glabrous or sparsely hairy.

primary branches densely appressed- to ascending-hairy;

peduncles appressed- to ascending-hairy or glabrous.

glabrous.

mostly glabrous or some of the proximal hairy.

green, often becoming reddish brown;

epicalyx bractlet lengths 0.5 times sepals (narrower);

hypanthium glabrous.

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

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

exserted to 1/3 from discs.

not exserted.
