Russia Flora: Sambucus coreana
Plant: Shrub, up to 4 m tall. Young shoots glabrous, green. Leaves: Leaves of fertile shoots 8-14(21) cm long, with 3-7 leaflets. Petiole 3-5.5 cm long, glabrous. Leaflets 7.5-9(13) cm long and 2.2-4(4.5) cm wide, elliptic or oblong-elliptic, apex acute to elongate-acuminate, base cuneate, margin rather finely serrate-dentate with 28-39 teeth on each side, glabrous or nearly glabrous on both surfaces. Inflorescence: Compact, glabrous. Flowers: Corolla 3-4 mm in diameter. Fruit: Drupes 3-4 mm long, dark purple. 

Distribution: Ussuri (southern). (Fig. 95). Found in deciduous and mixed forests along river valleys and large streams, also in shrub thickets. Flowering in June. Rather ornamental shrub.

General distribution: Japanese-Chinese (Northeast China, Korean Peninsula). Described from North Korea.

Sambucus mandshurica

Plant: Shrub, 3-4 m tall (usually lower in Soviet Far East). Young shoots glabrous or very sparsely pilose, green. Leaves: Leaves of fertile shoots 7-20 cm long, usually with 5, rarely with 3 or 7 leaflets. Petiole 1.5-5 cm long, glabrous or nearly glabrous. Leaflets 4-10 cm long and 1.5-4 cm wide, lanceolate, broadly lanceolate or oblong-elliptic, apex ± long caudate-acuminate, base rounded-emarginate or cuneate, margin serrate-dentate with (24)30-39 teeth on each side, both surfaces glabrous or with sparse and fine disappearing pubescence along main veins, upper surface green, lower surface characteristically glaucous-whitish. Inflorescence: Rather compact, during flowering 2.5-6 cm long and 3-7 cm wide, glabrous or very weakly pilose. Flowers: Corolla 5-6 mm in diameter, greenish-yellow. Fruit: Drupes spherical, 4.5-5.5(6) mm in diameter, bright red.

Distribution: Dauria, Lower Zeya (Fig. 96). Found in deciduous forests, mainly on slopes, stone fields and rocks; ascending to lower part of alpine zone. Flowering in June. Rather ornamental shrub.

General distribution: Eastern Siberia (Baikal region and Chita region); Mongolia (northern and eastern), Japanese-Chinese (Northeast China). Described from Northeast China.

Note: All Far Eastern species of series Racemosae are very closely related and can probably be considered as subspecies of the polymorphic species S. racemosa s. l. A new critical revision of East Asian elders using karyosystematic methods is needed.

Sambucus latipinna

Plant: Shrub, up to 5 m tall. Young shoots glabrous, often anthocyanin-colored. Leaves: Leaves of fertile shoots 7-20 cm long, with 5-7 leaflets. Petiole 2-4.5 cm long, glabrous. Leaflets 3-8 cm long, rhombic-elliptic or broadly elliptic, apex abruptly acuminate, base cuneate, margin ± coarsely dentate, with (12)16-30 teeth on each side, rather thick, both surfaces glabrous or nearly glabrous. Inflorescence: Spreading, glabrous. Flowers: Corolla 3-4.5(5) mm in diameter. Fruit: Drupes 3-4.5 mm long, dark purple. (Table XXIX).

Distribution: Ussuri (southern). (Fig. 95). Found in valley forests and shrub thickets along rivers and streams. Flowering in June. One of the most ornamental elderberries in the USSR, striking due to its glossy foliage.

General distribution: Japanese-Chinese (Northeast China, Korean Peninsula). Described from Korean Peninsula.
