proximal blade margins entire or serrate;

juvenile blade glabrous, pilose, or puberulent abaxially.

stipules absent or rudimentary on early ones, rudimentary or foliaceous on late ones (apex acute);

petiole 1–6 mm, long-silky adaxially;

largest medial blade (sometimes hypostomatous, glands submarginal), linear, lorate, narrowly elliptic, or narrowly oblanceolate, 40–120 × 7.5–16 mm, 3–8.5 times as long as wide, base cuneate or convex, margins flat, remotely spinulose-serrulate, apex acuminate, acute, or caudate, abaxial surface not glaucous, densely to sparsely long- or short-silky or villous, hairs appressed or spreading, straight or wavy, adaxial dull, sparsely long-silky or villous;

proximal blade margins entire;

juvenile blade yellowish green, very densely long-silky or villous abaxially.
