Russia Flora: Plant: Shrub, up to 2.5 m tall. Overwintering buds 4 mm long, acuminate-ovate, brown; their outer scales in 2(4) pairs, scales of external pair formed by persistent expanded petiole bases, densely white-pubescent at margin. Leaves: Leaf blade broadly ovate to ovate-lanceolate, apex acute or acuminate, base cuneate or rounded, margin varying from coarsely crenate-dentate to entire (often on same branch or shoot), 2.5-6.5(8) cm long and 1-3.5(4) cm wide, both surfaces glabrous, pilose along main veins (pubescence more developed on lower surface). Petiole 2-7 mm long. Inflorescence: Sessile, 2-flowered; pedicels 3-6 mm long, glabrous. Flowers: Calyx limb persistent in fruit, 4-merous, with lobes 8-12(14) mm long and 2-3.5(6) mm wide. Corolla 12-15 mm long, limb with 4 obovate, slightly twisted yellowish-pink petals, 7-8 mm in diameter. Fruit: Drupe ovoid-cylindrical, with 4 small ribs. (Table XXIX). Flowering in June.
Distribution: Ussuri (Fig. 97). Found in upper belts of mixed coniferous-broadleaved forests and in spruce-fir forests, as well as in their derivative plant communities, preferring shrub thickets at forest edges, rocky slopes, and watershed ridges and rocks, where it often takes a prostrate form.
Notes: Ornamental shrub with fragrant flowers; honey plant. Included in the list of rare plants of Soviet Far East (Kharkevich, Kachura, 1981); in our view, should belong to category 3 - "declining species" rather than category 2 - "rare species".
General distribution: Japanese-Chinese (Northeast China, Korean Peninsula). Described from Korean Peninsula.
