greenish, glandular-villous (without persistent tomentum, stipitate glands mostly 0.3–1 mm, often variable, stalks broadened toward bases, about equaling gland widths).

blades (crowded, internodes 1–5, sometimes to 10 mm) narrowly obovate to subspatulate, 1–3(–6) cm × 2–8 mm (distal smaller, oblanceolate to narrowly oblong or linear), bases subclasping, usually decurrent 1–2 mm, margins weakly revolute, faces mostly concolor to weakly bicolor, abaxial gray-tomentose, adaxial usually gray-tomentose, sometimes glabrescent, neither glandular.

blades mostly oblong-lanceolate, 2.5–7 cm × 4–20 mm, bases not clasping, not decurrent, margins flat, faces bicolor, abaxial white to gray with lightly persistent tomentum, adaxial green, both minutely stipitate-glandular.
