acacia (locust) [akatsiia]
|The various trees and shrubs of the genus Robinia, pea family, Leguminosae,
are known as locusts. Native to North America, these legumes bear pinnately
compound leaves, fragrant flowers in drooping clusters, and small, flat
seed pods. The most important tree species is the black locust, R. pseudoacacia,
or false acacia, which is native to the eastern and central United States
but has been naturalized in parts of Europe and Asia. Its heavy, hard, and
durable lumber is valued for fence posts, insulator pins, and railroad ties.
Other species include the clammy locust, R. viscosa, and the New Mexican
locust, R. neomexicana.
