Stipules setaceous to narrow linear, generally aristate, yellow green to brown purple, eglandular to glandular (1-2 nectaries), 8.8-18.1 x 0.2-1.4 mm (including an arista 0-2.7 mm), early deciduous. Petiole 1.3-3.8 cm long, green to dark green, slightly canaliculate adaxially, glabrous (pubescent on pseudoracemes), bearing two conspicuous oval sessile glands (about 1 mm long), at or below the middle (0.4-1.3 cm from petiole base). Leaves simple, unlobed, 10.5-21 x 5.5-11 cm, glabrous throughout, green to dark green, adaxial surface lustrous, cordate to rounded at base, obtuse to acute at apex, mucronate and acuminate; margin entire (rarely glandular-serrulate).
