Buds 2 to 2.5 mm. long, ovoid, subacute, glabrous, straw-colored; stipules caducous. Leaves evergreen, thin and hard, 10 to 15 cm. long, 4 to 6 cm. broad, broadly lanceolate to oblanceolate, long-acuminate, the bases cuneate to rounded or appar-ently truncate and then minutely cuneate, entire or the margins slightly wavy but scarcely toothed, somewhat crisped, minutely revolute, both surfaces glabrous or sparsely stellate-pubescent at the base of the midrib above, dully shining; veins 12 to usually 15 or 18 on each side with evanescent intermediates, branching (often doubly) and anastomosing toward the margin, impressed above but slightly raised (as is the reticulum) within the grooves, quite prominent beneath, the reticulum less so; petioles about 4 mm. long (excluding the decurrent lamina), 1.5 to 3 mm. thick, glabrous or sparingly stellate-pubescent, dark reddish-brown.
