The lower leaves are sometimes entire, with very sparse short hairs on both surfaces, 3 main veins arising from the base, with a pair of curved veins on each side, extending to the upper part of the leaf, or anastomosing with the lowermost lateral veins near the margin, 2-3(-5) pairs of lateral veins, filiform stipules, 0.3-0.4 millimeters long, clearly visible on the upper surface; slender petiole, 0.5-2(-5) centimeters long, smooth and hairless; membranous stipules, pale green, oblong, 3-5 millimeters long, semi-persistent.
