Leaves always opposite, not clustered at apices of branchlets; stipules absent; petiole green, slender, 1-2.5 cm, densely stellate-pubescent; leaf blade green when young, ovate to ovate-lanceolate, 3.5-10 × 1.8-6 cm, papery, abaxially densely stellate-pubescent, or only so in vein axils, adaxially with sparse, simple, forklike, or stellate hairs, or hairy only on midvein, midvein raised abaxially, lateral veins 5- or 6(-8)-jugate, pinnate, arched, branched, ending in teeth, raised abaxially, impressed adaxially, veinlets transverse, slightly raised abaxially, impressed adaxially, not lobed, base broadly cuneate to rounded or slightly cordate, with 0 or 1 circular gland on both sides of midvein near base, margin remotely serrate except at base, apex caudate-acuminate.
