Flora of North America species comparison

stipules rudimentary or foliaceous on early ones, usually foliaceous on late ones, (glands few or absent adaxially), apex acuminate, acute, or rounded;

petiole (margins covering groove, with spherical glands distally), (2–)3–10(–15) mm, glabrous or pilose adaxially;

largest medial blade (sometimes amphistomatous), very narrowly elliptic, lanceolate to narrowly lanceolate, or linear to lorate, (50–)70–103(–190) × (6–)7.5–17(–23) mm, 6–13 times as long as wide, base cuneate to convex, margins serrulate, apex acuminate, acute, or caudate, abaxial surface (not glaucous), glabrous or pilose, hairs white or ferruginous, wavy, adaxial slightly glossy, glabrous or pilose (especially on midribs);

proximal blade margins serrulate;

juvenile blade glabrous or pilose abaxially, hairs white and/or ferruginous.

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.

stamens 4–6;

filaments hairy on proximal 1/2 or basally;

anthers 0.4–0.6 mm, (axes strongly recurved).

adaxial nectary very narrowly oblong, 0.8–1.4 mm;
