Leaves basal and cauline or basal may not persist; petioles 3-35 mm from base to mid-stem with narrowly flanged bases, becoming sessile distally; blade reddish or purple-spotted beneath, somewhat ovate to nearly orbicular, approximately 10-49 mm long and 10-25 mm broad, leaves nearest base largest and persistent, palmate venation with 3-5 veins, base cuneate to truncate or nearly cordate, margins irregularly toothed or nearly lacerate, commonly doubly-toothed, 4-9 main teeth per side, sometimes sublacerate to sublyrate near base, apex acute to obtuse, surfaces glabrous or hirtellous with hairs that are dull, cylindrical, sharp-pointed, eglandular.

Axillary flowers typically 2-12, emerging from nodes at mid- to ends of stems; fruiting pedicels usually 7-20 mm, longer than subtending leaves, becoming glabrous, occasionally glandular-villous on upper surface at axils; calyx nodding at 30-180 degrees, commonly purplish or purple-spotted, ovoid-campanulate, inflated, compressed across sagittal plane, usually 10-15 mm, hirtellous or appressed-hirtellous, or glabrous, slightly short-ciliate at sinuses, throat closing, upper lobe generally longer than lower lobe, slightly sickle shaped; corollas yellow, throat commonly with red spots, lower limb usually with a red splotch at base, symmetric bilaterally, weakly bilabiate; tube-throat widely cylindric, 8-12 mm, equal to or protruding 1-2 mm beyond calyx margin, limb expanded 6-12 mm; styles slightly rough or glabrous; anthers not protruding, glabrous.
