Catclaw, Wattle (Acacia)
Catclaw, Wattle Genus Details
The acacia genus contains primarily tropical and subtropical trees and shrubs, native primarily to Australia and Africa. Species native to North America grow in the hot, arid SW region of the U.S. Leaves are bipinnately compound with small compact, light yellow flowers and numerous prominent stamens (male pollen-bearing structure), 10 or more. Since acacias are in the legume or pea family, the fruits are dry pods. The short-lived trees grow rapidly up to 50 feet in height. Powdered acacia gum or gum arabic is used to thicken foods and pharmaceuticals. Inhalation of the powder can cause allergic symptoms.
