Base truncate to cordate (at mid-plant). Leaves at upper plant: bract-like and oblanceolate with a cuneate base. Nectary present at the base of midrib on the abaxial surface; the blades of all leaves adaxially glabrate or finely stellate-pubescent. Margins serrate to dentate: leaves near base of the plant not seen. Leaves at upper plant: bract-like and oblanceolate leaves with serrate margin. Petiolate; leaves at mid-plant: petioles 3-8.5 cm long, sparsely to densely fine stellate-pubescent, or sometimes with a few coarse stellate hairs.
