proximal blade margins entire or serrate;

juvenile blade glabrous, pilose, or puberulent abaxially.

stipules rudimentary on early ones, foliaceous on late ones, apex acuminate, acute, or rounded;

petiole shallowly grooved adaxially, 3–7 mm, tomentose adaxially;

largest medial blade lorate, very narrowly elliptic, or oblanceolate, 58–144 × 11–30 mm, 2.8–7 times as long as wide, base convex or cuneate, margins slightly revolute, entire, irregularly serrate, serrulate, or sinuate, apex convex, acute, or acuminate, abaxial surface glaucous (sometimes obscured by hairs), sparsely to densely tomentose or woolly, hairs wavy, adaxial slightly glossy or dull, sparsely tomentose or villous;

proximal blade margins entire;

juvenile blade reddish or yellowish green, densely long-silky abaxially, hairs white or gray.

abaxial nectary absent, adaxial nectary narrowly oblong or oblong, 0.4–0.9 mm;

filaments distinct, glabrous;

stamens usually 1, rarely 2;

anthers ellipsoid or shortly cylindrical, 0.4–0.7 mm.
