形態特徵

Semi evergreen twining to scandent woody vines; branchlets pubescent.
Leaves chartaceous, broadly lanceolate, ovate to elliptic, 3–8 cm long, 2–3 cm broad, base rounded to subcordate, apex acute to obtuse or rounded, entire, upper surface slightly pubescent, lower surface densely so, midrib distinct, raised on both surfaces; petiole 3–10 mm long, densely pubescent.
Inflorescences axillary, 2-flowered cymes; peduncle usually solitary, ca. 3–15 mm long, pubescent; bracts below each pair of flowers foliaceous, petiolate, densely pubescent; bracteoles suborbicular, pubescent. Flowers in pairs; calyx tube conical, pubescent; corolla 3–4 cm long, pubescent and glandular without, white tinged with purple, turning yellow in age, tube ca. 2 cm long, limb ca. 2 cm long; style 1; stamens 5, exserted.
Fruit globose, black, 3–4 mm across.
This species is highly variable in indumentum and leaf shape, resulting in many infraspecific taxa being named and many hybrids with other species suspected. Lonicera shintenensis, with limited specimens available, is difficult to distinguish from this species, differing only by its small triangular bracts. It is possible that L. shintenensis is a hybrid between L. japonica and L. hypoglauca or a related species, or that it might be recognizably distinct below specific rank.
