Winter buds oblong-ovoid, with 2 pairs of separate scales; scales ovate-lanceolate, stellate-pubescent. Leaves always opposite, not clustered at apices of branchlets; stipules often absent; petiole reddish purple, robust, 5-10 mm, stellate-pubescent; leaf blade brownish green when young, ovate or elliptic to oblong-rhombic or obovate, 4-10 × 1.5-2.5 cm, papery to thickly papery, abaxially stellate-pubescent on midvein and lateral veins, rarely densely stellate-tomentose, adaxially densely pubescent on midvein but glabrous elsewhere, midvein raised abaxially, lateral veins 2-4-jugate, lowest pair often elongating to upper part of blade, thus appearing triplinerved, pinnate, arched, branched, ending in teeth, conspicuously raised abaxially, slightly impressed adaxially, veinlets transverse, conspicuously raised abaxially, slightly impressed adaxially, not lobed or sometimes almost 3-lobed, base cuneate to rounded, with 0 or 1 circular gland on both sides of midvein near base, margin subentire or large dentate, apex acute to shortly acuminate. Flowers appearing after leaves; inflorescence a compound umbel-like cyme, at apices of lateral branchlets, 5-8 cm in diam.; rays whorled; first node of inflorescence with 4-8 rays, dense, stellate-pubescent and with red-brown glandular dots, without large sterile radiant flowers; peduncles (0.5-)2-5 cm; bracts and bracteoles late deciduous or persistent, leaflike, green, linear-lanceolate, sparsely hairy.
