           The first few leaves after the cotyledons in the seeding of Acacia are pinnately compound but the petioles of the upper compound leaves are flattened and they bear few pinnae. The adult plant has only parallel veined leaf like flattened petioles but without any pinnae. These observation lead us to the conclusion that:

A) The leaves in the adult plant are reduced to phyllode while the seeding leaves are unreduced

B) The green parallel veined structures in the adult plant are phylloclades

C) The plant exhibits heterophyJJy bearing simple leaves in the adult plant and compound leaves in the seeding

D) The adult plant leaves are a case of reversion where they become simple like cotyledons
