± appressed-hairy.

densely spreading-hairy 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 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 hairy;

peduncles hairy or glabrous.

primary branches densely hairy;

peduncles sparsely hairy or glabrous.

glabrous.

glabrous or some of the proximal 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.

green, often becoming reddish;

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

hypanthium rounded at base, usually sparsely to densely spreading-hairy, rarely glabrous.

exserted from discs (distinctly longer than hypanthia).

exserted 1/5 from discs.
