proximal blade margins entire or serrulate;

juvenile blade reddish, glabrous abaxially.

stipules (sometimes marcescent), foliaceous, (sometimes obscured by hairs);

petiole (shallowly grooved adaxially), 2–5.5 mm, (usually shorter than or barely exceeding subtended bud, villous adaxially);

largest medial blade hypostomatous or amphistomatous, narrowly oblong, narrowly to broadly elliptic, lanceolate, or obovate, 13–64 × 6–22 mm, 1.6–5.5 times as long as wide, base convex, margins slightly revolute, entire (obscured by hairs), apex acuminate or acute, abaxial surface densely villous or woolly to pilose, hairs straight or wavy, adaxial slightly glossy, moderately densely to sparsely villous;

proximal blade margins entire;

juvenile blade abaxially densely long-silky.
