Ligustrum compactum, L.confusum and L.robustum are recorded in Mizoram.

Hi, Sawmliana ji,

I think it may come out to be Ligustrum robustum (Roxb.) Blume

[J.M. Garg]

On further scrutiny, I will go for Ligustrum confusum Decne. 

[J.M. Garg]

I further examined it in the light of details in Flora of China:

Ligustrum confusum Decaisne:

Shrubs or small trees to 8 m. Branchlets terete, puberulent when young, glabrescent. Petiole 4-5(-10) mm, glabrous or puberulent; leaf blade ovate to elliptic, sometimes lanceolate, 2.5-7(-10) × 1.3-3(-5) cm, thin leathery, glabrous or sometimes pubescent near base of midrib adaxially, base cuneate to broadly cuneate or rounded, apex acuminate or acute; primary veins 4-6 on each side of midrib. Panicles terminal, 4-11 × 2-8 cm; rachis puberulent to pubescent. Flowers subsessile. Calyx 1-1.5 mm, glabrous. Corolla 4-5 mm; tube ca. as long as lobes. Stamens not exceeding corolla lobes; anthers 1-1.5 mm. Fruit black or black-brown, subglobose to obovoid, 6-11 mm in diam.

Thickets near gullies; 800-2100 m. Xizang, Yunnan [Bangladesh, Bhutan, India, Myanmar, Nepal, Sikkim, Vietnam]

Ligustrum compactum (Wallich ex G. Don) J. D. Hooker & Thomson ex Brandis :

Shrubs or small trees to 12 m, semievergreen. Branchlets terete, pubescent when young, glabrescent or velutinous. Petiole 0.5-2.5 cm, glabrous, puberulent or velutinous; leaf blade elliptic-lanceolate to ovate-elliptic, 5-15 × (2-)3-6(-8) cm, papery, glabrescent, sometimes midrib only puberulent adaxially, or velutinous, base rounded to cuneate, apex acute to long acuminate; primary veins (6-)9-15 on each side of midrib, slightly prominent. Panicles usually terminal, 7-20 × 7-16(-24) cm; rachis angular, particularly in fruit. Flowers subsessile. Calyx 1-1.5 mm. Corolla 3.5-5 mm; tube ca. as long as lobes. Stamens reaching apex of corolla lobes; anthers 1-2.5 mm. Fruit blue-black or black, ellipsoid or subglobose, 7-10 × 4-6 mm, usually slightly curved.

Valleys; 600-3400 m. Hubei, Sichuan, Xizang, Yunnan [India, Nepal]

As apex long acuminate, leaves and panicles comparatively large, rachis angular, fruits blue-black and slightly curved, I feel it may be Ligustrum compactum (Wallich ex G. Don) J. D. Hooker & Thomson ex Brandis
