Phyllode

 

a petiole that is broadened in the shape of a leaf and fulfills the functions of the leaf blade, which is absent or partially reduced. Phyllodes are present in many Australian acacias and in some Australian cassias. Phyllodes characterize a number of plants that grow in the USSR, including Lathyrus missolia. Phyllodes apparently serve as an adaptation to a decrease in transpiration.
