Description
Evergreen trees and shrubs of the species of Acacia of the Leguminosae family. The trees are widely distributed through India, Hawaii, and Australia. Several commercial products are produced by these trees. Gum arabic is produced from the sap and pods of Acacia arabic and Acacia senegal. Kordofan gum comes from Acacia verek and is used in jellies, candies, and other food products. Cutch is a brown or black dye obtained from Acacia catechu. Wattle bark produces a strongly astringent tannin from Acacia mimosa and Acacia mollisima trees. Strong, coarse bast fibers obtained from the Acacia leucophloea trees are used for ropes and nets. Some acacias are used for timber such as the Acacia melanoxylon (Australian blackwood), Acacia formosa (sabicu), Acacia seyal (shittah tree), and the Acacia koa (koa). The strong, elastic, hardwood is used for furniture, walking sticks, and tool handles.
Synonyms and Related Terms
Acacia melanoxylon (Australian blackwood); Borneo cutch; Acacia arabic; Acacia senegal; Acacia verek; Acacia catechu; Acacia mimosa; Acacia mollisima; Acacia leucophloea; Acacia koa; Acacia formosa (sabicu); Acacia seyal (shittim wood); Akacie (Dan.); Akazien (Deut.); acacia (Esp., Fr., It.. Ned.); Akacja (Pol.); acácia (Port.)
Other Properties
Paper fiber type: hardwood. Using transmitted light microscopy, pulp is idenfied by small vessel elements with profuse alternate pitting that appears in horizontal rows. Perferations are simple . Appearance with Graff "C" stain: dark blue, varies with bleaching. Average dimensions of fibers: length, 0.8mm. 14μm wide. Common pulping method: kraft.
