Deutzia chanetii H. Léveillé; Philadelphus coronarius Linnaeus var. pekinensis (Ruprecht) Maximowicz; P. pekinensis f. lanceolatus S. Y. Hu; P. rubricaulis Carrière.
Shrubs 1-2 m tall. Branches of previous year brown, glabrous, those of current year yellow-brown. Petiole 5-12 mm; leaf blade ovate, broadly elliptic, or lanceolate, 4-9 × 1-4.5 cm, or elliptic or lanceolate and 2.7-5 × 1-2.5 cm on flowering shoots, both surfaces glabrous, occasionally bearded at vein axils, veins 3-5, basifugal, base cuneate or broadly so, margin serrate, rarely entire, apex acuminate or long acuminate. Racemes 5-7(-9)-flowered; rachis yellowish green, 3-5 cm, glabrous; pedicels 3-6 mm, glabrous. Calyx yellowish green when dry, glabrous; lobes ovate, 3-4 × ca. 2.5 mm, veined, apex acute. Corolla discoid; petals obovate, 0.9-1.2 × ca. 0.8 cm. Stamens 25-28, longest ones ca. 1.7 cm. Disc and style glabrous. Style distally slightly divided, slender, 4-5 mm; stigmas mallet-shaped, ca. 1 mm, shorter than anthers, adaxially short or broad. Capsule subglobose or obconical, 5-7 mm in diam. Seeds 3-4 mm, shortly tailed. Fl. May-Jul, fr. Aug-Oct.
Mixed forests, thickets, mountain slopes; 700-900 m. Hebei, ?Hubei, ?Jiangsu, Liaoning, Shaanxi, Shanxi, ?Zhejiang [Korea].
In FRPS, two varieties were recognized: var. pekinensis and var. lanceolatus S. Y. Hu. However, those names were actually published as forms by Hu (J. Arnold Arbor. 36: 95. 1955) and have never been validly published at varietal rank.
