Acacia melanoxylon young plant with phyllodes replacing bipinnate leaves
In most of these, the leaf-like foliage of mature plants is actually modified leaf petioles, termed phyllodes. Among phyllodinous Acacia species, bi-pinnate foliage occurs only on very young plants. These phyllode-bearing species are classified into three major Sections of the genus Acacia: Phyllodineae with almost 400 species, Juliflorae with about 255 species, and Plurinerves with about 215 species (Maslin, 2001).
