| In the leaves, petioles and stipule structure of three parts, the lack of part or two parts of the leaf is called incomplete leaf. Such as tea, cabbage, cloves and other plant leaves. No stipules of the most common, such as privet, lilac, forsythia, tea, cabbage, sweet potato leaves; while no stipules and petioles, such as lettuce, endive dish, carnation, tobacco leaves (also known as sessile leaf); no less leaf blades, such as Taiwan acacia, leaves completely degraded, petiole flat, can carry out photosynthesis, known as the petiole-like. |
