several from base, (slender), erect or outer decumbent, (usually branched, branches filiform, bud clusters of growing plants drooping), to 2.5 dm.

(ascending to erect, petiole slender);

blade oblanceolate to obovate, 3–8 cm, (base tapering to petiole), margins incised or dentate with broad teeth, (apex acute to obtuse).

blade orbicular to broadly spatulate, 1–2.4 cm, margins entire or sinuate.

blade linear-oblanceolate to oblanceolate, 1–2 cm, margins entire.

similar to basal, blade spatulate to oblanceolate or (distal) linear, (base cuneate), margins entire or sinuate.

dense (elongated or not in fruit, 2.5–8.5(–10) cm).
