Description
It is an evergreen shrub or small tree that reaches to a height of between 1-5 m . The branches are hairless, unarmed, young parts finely rusty and puberulent.
Leaves are alternate, pinnate with an unpaired terminal leaflet with (1-)3-5(-7) leaflets supported by a 2.5-5.5 cm long stalk. The leaflets are narrowly elliptical or oblong-elliptical with a size of 6-24 cm x 2-7 cm. The base is acuminate, margin is entire or minutely and distinctly with small teeth-serrate, lateral veins 6-12 pairs and supported with 3-8 mm long leaflet stalk.
Inflorescence is arising from the axils, paniculate, elongated up to 8 cm long, narrow, tri-pinnate, branches short, ascending, axes and bracteoles rusty covered with down and fine hair. Its flowers are about 5 mm long, fragrant; sepals are broadly egg-shaped to rotund, 1-1.5 mm long, margin ciliolate; petals are reverse egg-shaped to elliptical, 5 mm x 2.5 mm, hairless, white with stamens up to 3.5 mm long.The ovary is ovoid, up to 2.5 mm long, coarsely blister-like prominences-glandular, usually 5-celled, style scarcely distinct.
Its fruit is a berry, nearly spherical, white to pink or crimson, 10-13.5 mm in diametere, 1(-3)-seeded and edible.
Its seed is round to plano-convex, nearly longer than broad with the side parallel and green.
