In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.

Detailed explanation-3: -what is leaf blade? If you see the structure of the leaf it can be divided into two regions, the one from which the leaf is attached to the stem called as a petiole (cylindrical in structure) and the other broad flattened surface (mainly green) where maximum photosynthesis occurs is known as leaf blade or lamina.
