Flora of North America species comparison

densely spreading-hairy (to inflorescences).

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

stipules translucent, usually pale pink proximally, lobes turning brownish;

blade orbiculate or reniform-orbiculate, 9–11-lobed, margins flat or slightly undulate, basal sinuses narrow to almost closed, basal lobes sometimes overlapping, middle lobes with lateral sides convex or slightly concave at base, shorter than to as long as their half-widths;

incisions absent;

teeth slightly connivent or not, ± symmetric, apex acute or subacute, surfaces densely hairy throughout.

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 densely hairy;

peduncles pubescent or almost glabrous.

primary branches densely appressed- to ascending-hairy;

peduncles appressed- to ascending-hairy or glabrous.

glabrous.

mostly glabrous or some of the proximal hairy.

epicalyx bractlet lengths 1 times sepals (as wide), often with blunt teeth, glabrous;

epicalyx bractlets and sepals patent after flowering, giving appearance of an 8-point star;

hypanthium usually densely, occasionally sparsely, hairy (in proximal 1/2).

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

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

exserted from discs (distinctly longer than hypanthia).

not exserted.
