1–5, sparsely to moderately strigoso-puberulent.

1–10+, erect, proximally glabrous, glabrous or sparsely villoso-strigose in arrays; often with short fascicles in axils of mid to distal cauline leaves.

basal petioles 3–5 cm, blades oblanceolate or spatulate to ovate or rotund, 2–4 cm (excluding petioles);
