Flora of North America species comparison

± appressed-hairy.

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

stipules green or slightly purplish tinged, turning brown;

blade orbiculate, 7–9-lobed, margins undulate, basal sinuses appearing closed, basal lobes overlapping, middle lobes rounded, as long as or longer than their half-widths;

incisions relatively short to long;

teeth ± connivent, slightly asymmetric, apex acute, abaxial surface with nerves hairy throughout, internerve regions glabrous or densely hairy throughout, adaxial glabrous or hairy 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 hairy;

peduncles hairy or glabrous.

primary branches densely hairy;

peduncles sparsely hairy or glabrous.

glabrous.

glabrous or some of the proximal rarely sparsely hairy.

epicalyx bractlet lengths equal to slightly longer than sepals (usually almost as wide);

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

hypanthium usually shorter than sepals, glabrous.

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

hypanthium usually glabrous or sparsely hairy (on proximalmost flowers).

exserted from discs (distinctly longer than hypanthia).

exserted 1/3 from discs.
