Abstract

The present study has been devoted to the morphological variations within Acacia seyal var. seyal, one of the multipurpose wide-spread leguminous trees in Africa and Asia. Three categories within this variety, differentiated by bark color, have been studied at mature and seedling's stages. The study has entailed quantitative measurements that ananlysed statistically where significant differences were detected among the measurable data. Consequently, three different forms, following the bark color have been suggested.
