description
Prinsepia utilis is a 1 to 5 meter high shrub with gray-green and thick branches and green to gray-green, angled, brown-haired to almost bare branches. The thorns are up to 3.5 centimeters long, almost bare and often leafy. The winter buds are purple-red, ovate to oblong and almost bare. The leaves have a bare stalk about 5 millimeters long, stipules were not observed. The leaf blade is simple, 3.5 to 9 centimeters long and 1.5 to 3 centimeters wide, oblong to ovate-lanceolate, with a pointed or long pointed tip, a broadly wedge-shaped to rounded base and a finely serrated leaf margin.
The inflorescences are 3 to 6 centimeters long, multi-flowered clusters in the leaf axils or on short branches. The inflorescence axis is hairy brown and soon balding. The bracts and bracts are also hairy brown, lanceolate and balding. The flowers have a diameter of about 10 millimeters. The flower stalk is 4 to 8 millimeters long, hairy brown and soon balding. The flower cup is cup-shaped and has brown hair on the outside. The sepals are round to broadly ovate, initially brown haired on the outside and densely brown haired on the edge. The petals are white, broadly ovate with a short nailed base and the edge of the leaf bitten off at the tip. The stamens are arranged in two or three whorls . The ovary is bald, the stylus short. The stone fruits are red-brown to black-brown, elongated to obovate-elongated and reach a diameter of about 8 millimeters.

The number of chromosomes is 2n = 32.
distribution
The natural range is in China in the provinces of Guizhou , Sichuan , Yunnan and in the autonomous region of Tibet , in Bhutan, Nepal, in the north of India and in Pakistan. Prinsepia utilis grows on mountain slopes, wastelands, valleys and along paths at an altitude of 1000 to 2600 meters on acid to alkaline, sandy to loamy, well-drained soils in sunny to partially shaded locations.

use
The fruits are eaten raw or cooked as fruit . The seeds are used to make oil that is used in cooking.
