Characteristics

Shrubs, evergreen, to 2 m tall. Bark gray-brownish. Branchlets of current year red-brownish, lustrous, with small prominent lenticels, glabrous; branchlets of previous year grayish, terete, glabrous, with dispersed, small, rounded lenticels. Winter buds ovoid-oblong, with 1 pair of separate scales; scales reddish brown, glabrous, apex acute. Leaves always opposite, not clustered at apices of branchlets; stipules absent; petiole green, slender, 1-2 cm, glabrous; leaf blade purplish when young, ovate to ovate-lanceolate or elliptic to elliptic-oblong, or linear-lanceolate or oblanceolate, 3-9(-11) × 1-4.5 cm, leathery, abaxially sometimes stellate-pubescent in axils of veins, adaxially glabrous, midvein raised abaxially, triplinerved, veins reaching to middle of leaves or above, pinnate, arched, branched, anastomosing near margin, raised abaxially, impressed adaxially, veinlets transverse, conspicuous abaxially, inconspicuous adaxially, not lobed, base subrounded or cuneate, both sides slightly asymmetric, without glands, margin usually remotely serrate, apex acuminate or acute. Flowers appearing after leaves; inflorescence a compound umbel-like cyme, terminal, (2-)4-7 cm in diam.; rays whorled; first node of inflorescence usually with 7 rays, lax, glabrous, without large sterile radiant flowers; peduncles 1.5-2.5(-4) cm, slender; bracts caducous, leaflike, green, linear to linear-lanceolate, glabrous; bracteoles scalelike. Flowers on rays of 3rd order, not fragrant; pedicels 1-2 mm, slender. Calyx greenish; tube obconical, ca. 0.6 mm, glabrous; lobes broadly triangular-ovate, very small, ca. 0.4 mm, glabrous, apex obtuse. Corolla greenish white, rotate, ca. 4 mm in diam., outside glabrous, inside with long hairs at base; tube ca. 1 mm; lobes spreading, broadly ovate, ca. 1 mm, nearly as long as tube, apex rounded, margin entire. Stamens usually slightly longer than corolla, inserted near base of corolla tube; filaments 2-3 mm; anthers yellow, subglobose, ca. 1 mm. Styles nearly as long as calyx lobes; stigmas subsessile. Fruit not turning red, maturing blue-blackish, lustrous, subglobose or ovoid, (3-)5-6 × (3-)3.5-4 mm, base rounded, apex acute, glabrous; pyrenes globose, ca. 4 × 3 mm, with 1 very small and shallow ventral groove or without groove, apex rounded. Fl. Mar-May, fr. May-Oct.
More
Shrub. Leaves thinly coriaceous, glabrous except for the bearded axils of primary side-nerves on the underside, ovate to ovate-lanceolate, often somewhat falcate, 6—8—(11) by 2½-4(-5½) cm, apex acute to long-acuminate, base cuneate to broadly cuneate, margins on both sides ½-1(-2) cm above the base with an impressed small gland, nearly entire, only minutely and distantly serrulate, teeth reduced to mucros hardly ½ mm long; nervation prominent beneath, basal primary nerves nearly as prominent as the midrib (leaves therefore triple-nerved), more apical 2-3 pairs less prominent, all side-nerves anastomosing; petioles 1-2 cm. Inflorescence umbellate, corymbiform, (3-)5-7 cm across, axes glabrous; peduncle short, 2(-5) cm; primary rays 5-7. Bracts and bracteoles minute, ovate, ciliate. Calyx-limb 1 mm long, obscurely lobed; lobes ovate, obtuse, glabrous, about ½ mm. Corolla whitish or yellowish green, 4 mm wide, campanulate-rotate, globular in bud; tube broad, scarcely 1 mm long, hairy within, lobes ovate to oblong, rounded, recurved in anthesis, 1½ mm. Stamens exserted; filaments adnate near base of corolla, in bud with inflexed top, 2-2½ mm; anthers broadly elliptic, ¾ by ½ mm. Ovary ¾-1 mm long and wide, glabrous. Drupe globose-ovoid, bluish black, 4-5 by 4 mm. Mesocarp thin, scanty fleshy; endocarp thin, orbicular in cross-section, ventrally slightly 1-grooved. Seed ovoid; albumen deeply ruminate.
