Flora of North America species comparison

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

sparsely appressed-hairy throughout or glabrous in distal 1/2.

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, colorless, usually flushed pale wine red proximally, apex pale green, sometimes with pale wine red margins and veins;

blade reniform-orbiculate, 7–9-lobed, margins flat, basal sinuses narrow or closed, middle lobes as long as and rounded to longer than their half-widths;

incisions long or short, 2–5 mm;

teeth usually connivent, symmetric to slightly asymmetric, apex acute, abaxial surface with nerves hairy throughout or in distal 1/2 only, internerve regions usually glabrous (except sometimes on 2 basal lobes), adaxial glabrous or slightly hairy at margin.

primary branches sparsely to densely hairy;

peduncles glabrous or sparsely hairy.
