Macledium is a genus of flowering plants in the family Asteraceae.[2] Both Macledium and Dicoma are distributed largely in tropical and southern Africa.[3] Macledium is distinguished from genus Dicoma by a large number of characters relating to morphology and anatomy of phyllaries, corolla, anthers, style, cypsela and testa.[2]
