The buds are egg-shaped to elongated, tomentose and have a blunt tip. The leaves have a 2 to 5 millimeter long, finely hairy petiole. The leaf blade is elliptical or elliptical-lanceolate, 1.5 to 5.2 inches long and 0.6 to 1.5 inches wide, entire, with a blunt or pointed tip and a blunt or pointed base. The upper side of the leaf is dull green and sometimes tomentose, the underside is blue-green.^[1]
