LEAVES with petioles 7-23 cm long, drying 3-7 mm diam., subterete, sulcate adaxially, drying with sharp margins, rounded abaxially; geniculum sharply sulcate, 0.5-1 cm long; blades subcoriaceous, elliptic to ovate-elliptic, acuminate and apiculate at apex, obtuse to rounded or sometimes cuneate at base, 23-36 cm long, 12-19 cm wide, drying yellow-green to yellow-brown; midrib prominently riased on both surfaces, drying angular and paler than surface below; primary lateral veins 6-9 per side, departing midrib at 40-60° angle, moderately straight to the margin, then markedly ascending and merging with the margin or loop-connecting with the next higher vein, raised on both surfaces; tertiary veins drying prominulous below; collective vein lacking or arising below the middle of the blade.
