The leaves are sessile or have a bare stalk up to 2.5 centimeters long. The leaf blade is pinnately divided into three to nine segments, 1 to 4 inches long and 0.4 to 2.5 inches wide. The leaf blade and the lobes are lanceolate, elliptical, egg-shaped or obovate, glabrous and covered with conspicuous, point-shaped glands on the underside.

Syringa protolaciniata flowers from April to June, the fruits ripen from June to August.
The number of chromosomes is 2n = 46.
distribution
The natural range is in southwest China, in the east and south of Gansu Province and in the east of Qinghai . Syringa protolaciniata grows in forests on steep mountain slopes at heights of 800 to 1200 meters on dry to fresh, weakly acidic to strongly alkaline, sandy-humic or loamy-humic, moderately nutrient-rich soils in sunny to light-shady locations. The species is frost hardy . It is assigned to winter hardiness zone 6b with mean annual minimum temperatures of −20.5 to −17.8 ° C.
Systematics
Syringa protolaciniata is a kind from the genus of Lilac ( Syringa ) in the family of Oleaceae (Oleaceae). There the genus is assigned to the tribe Oleeae. The species was first scientifically described by Peter Shaw Green and Mei Chen Chang in 1989 . The genus name Syringa was chosen by Linnaeus in 1753, previously from around the 16th century the name was used both for the common lilac ( Syringa vulgaris ) and for the European pipe bush ( Philadelphus coronarius ). It was probably derived from the Greek "syrigs", a wind instrument that can be made from the branches of the pipe bush.
use
Syringa protolaciniata is very rarely used as an ornamental shrub because of its decorative flowers .
