Leaf tendrils - leaf modification for providing mechanical support for climbing - Ex: Pea leaf lets, Complete leaf of Lathyrus, Stipules of Smilax, leaf apex of Gloriosa, Petiole of Nepenthes.
Spines - modified leaf for defence or protecion from grazing animals - Ex: Complete leaf as in cacti like Opuntia, leaf margin, apex and surface of Solanum xanthocarpum, leaf margin of Aloe, Stipules of Acacia arabica
Phyllodes - Any organ of leaf other than lamina modified as green photosynthetic structure - Australian acacia (complete petiole), lower half of petiole in Nepenthes. Stipules of Lathyrus and Pea.
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.
