Branches slightly flexuous, terete, nodose, about 1 1/2 lin. in diam. 1 ft. below the apex, densely lenticellate, glabrous; branchlets spreading or ascending, angular; internodes 3/4–1 1/2 in. long. Leaves opposite or subopposite, oblong, oblong-lanceolate or ovate-oblong, acute or obtuse at the apex, obtuse or more rarely rounded at the base, 1 1/4–2 3/4 in. long, 7–16 lin. broad, rigidly coriaceous, glabrous, penninerved, upper surface slightly glossy; lateral nerves patulous, 4–6 on each side, anastomosing well within the margin, slightly raised on the upper surface, very inconspicuous or not visible on the lower; petiole 2 1/2–4 lin. long, channelled.
