Ammodendron

Ammodendron

 

a genus of deciduous trees and shrubs of the family Leguminosae. The plants range in height from 0.5 to 8 m. A dense, silky pubescence imparts a grayish green coloration to the leaves. The leaves are from 1 to 6 cm long and have one or two pairs of mainly linear bracts; they resemble thorns with petioles and stipules. The violet flowers are in many-flowered racemes. The elongated and winged beans are laterally compressed; they have one or two seeds and are indehiscent.

There are seven species of Ammodendron, distributed in Kazakhstan, Middle Asia, the southwestern part of Western Siberia, and northwestern China. Six species are found in the USSR: four grow in sandy soils, and two (A. argenteum and A. eichwaldii) grow on rocky and clayey slopes. The plants are used as fuel and for stabilizing loose barchans. The roots are used for dying fabric. The species A. conollyi and A. karelinii are raised as ornamentals.
