Nodes inflated, young branches glabrous, compressed. Leaves thinly leathery, ovate-lanceolate or lanceolate, 6-14 cm long and 3.5-5 cm wide, apex long acuminate, acuminate part 10-15 mm long, base cuneate or slightly obtuse, rarely rounded, entire or shallowly wavy, both surfaces glabrous, lower vein axils with or without small pores; midrib raised on both surfaces of leaf, 7-13 on each side of lateral veins; petiole 8-15 mm long Stipules broadly triangular, arising from the tip of the upper part of the young branch conical or awn tip, the tip of the old branch is often protruding tip, 3-6 mm long.

Cymes several clustered in leaf axils, each with 2-5 flowers, without a total pedicel or with a very short peduncle; flowers fragrant, with pedicels 0.5-1 mm long; bracts base ±connate, dimorphic, 2 broadly triangular, nearly equal in length and width, the other 2 lanceolate, 2 times as long as wide, leaf-shaped; calyx tubular, 2.5-3 mm long, calyx eaves truncate or 5-denticulate. Corolla white, length varies from breed to breed, generally 10-18 mm long, apically often 5-lobed, rarely 4-or 6-lobed, lobes often longer than Corolla tube, tip often obtuse; anthers protruding from Corolla tube, 6-8 mm long; style 12-14 mm long, stigma 2-lobed, 3-4 mm long.

Berries broadly elliptic, red, 12-16 mm long, 10-12 mm in diameter, exocarp dura, mesocarp fleshy, sweet at maturity; seeds raised abaxially, ventral flat, longitudinally grooved, 8-10 mm long and 5-7 mm in diam. Florescence from March to April
