proximal blade margins entire;

juvenile blade yellowish green, sparsely to densely tomentose abaxially, hairs white.

stipules absent or rudimentary on early ones, foliaceous or rudimentary on late ones;

petiole (deeply to shallowly grooved adaxially), (0.5–)1–3(–4) mm, (usually shorter than or barely exceeding subtended bud);

largest medial blade hypostomatous, narrowly oblong, oblong, narrowly elliptic, elliptic, narrowly oblanceolate, ovate, or obovate, base rounded, convex, cordate, or subcordate, margins flat, entire, apex rounded, acute, or convex, abaxial surface (sometimes obscured by hairs), densely villous, woolly, or long-silky, adaxial slightly glossy, pilose, villous, or long-silky to glabrescent, (hairs straight or wavy);

proximal blade margins entire;

juvenile blade very densely long-silky abaxially.

adaxial nectary oblong or ovate, 0.5–1 mm;

filaments distinct, glabrous or hairy basally;

anthers yellow or purple turning yellow, ellipsoid or shortly cylindrical, 0.7–1 mm.

abaxial nectary (0–)0.5–1.5 mm, adaxial nectary 0.5–1.4 mm, nectaries distinct or connate and cup-shaped;

filaments distinct or connate less than 1/2 their lengths, glabrous or hairy throughout or on proximal 1/2;
