description

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.

distribution and habitat

The plant called calafate and michai in Chile and Argentina is distributed in Chile from the Antuco volcano in the Bío-Bío region to the Osorno volcano in the lagos region , and in Argentina only in the west of the Neuquén and Río Negro provinces ; Berberis trigona is endemic to southwest South America. It is a bush of the undergrowth of southern beech forests.

Like many other Berberis species, the linear-leaved barberry is used as an ornamental shrub. It was introduced by Harold Comber in 1927.

Of Berberis linearifolia different varieties are maintained in culture:

  • berberis linearifolia 'Orange King' is a variety with large, orange flowers.

Hybrids

The linear-leaved barberry and Darwin's barberry are parent species of the natural hybrid Lolog barberry ( Berberis × lologensis Sandwith ). There are also natural hybrids with the box-leaved barberry ( Berberis microphylla ) known.
