The linear-leaved barberry grows as a thorny , evergreen shrub up to 2 meters in size . The bark of the branches is light gray to brownish (rarely dark reddish brown), has longitudinal cracks and becomes fibrous with age. The thorns are three-part and slightly curved, the thorn branches 3 to 18 millimeters long.
The stiff leathery leaves are glossy dark green, narrow-elliptical, lanceolate to linear, 1.7 to 5.4 inches long and 0.4 to 1.5 inches wide. The leaf margins are slightly rolled up towards the underside of the leaf, the petioles are 0.5 to 1.5 millimeters long and the leaf ends in a sting up to 2 millimeters long.
The inflorescence is an umbel-like cluster of 2 to 4 orange to red-orange flowers , about 9 millimeters long ; these are stalked 1 to 2.7 inches long and consist of 15 to 21 tepals . The fruits are blue-black, spherical and 7 to 10 millimeters in size and end in a 3 to 4 millimeter long style. The 5 to 9 seeds are 3.5 to 4 millimeters long.
Berberis trigona blooms in its homeland from November to February and mainly produces fruit from January to February.
