Fleshy leaves - These leaves store food materials or water or both - Ex: Onion, Garlic, Cabbage, Aloe, Bryophyllum.

Reproductive leaves - meant for vegetative propagation by having epiphyllous buds - Ex: Bryophyllum (notches of leaf margin), Scilla (Leaf apex), Wounded region of leaf in Begonia.

Trap leaves - leaves modified for attracting, catching, killing and digesting the protein part of insect for nitrogenous requirement as seen in insectivorous or carnivorous plants - Lamina of Nepenthes, leaflet of Dionaea or Venus fly trap, lamina of Drosera and segments of lamina of Utricularia are modified as insect traps.
