Reniform leaf is a term used in botany to describe a leaf that is shaped like a kidney. Synonyms for reniform leaves include orbicular leaves, cordate leaves, and suborbicular leaves. These leaves are usually small, measuring only a few inches in length. They can be found on a variety of plant species, including some members of the legume family. Reniform leaves are typically glossy and have smooth edges, making them difficult to confuse with other leaf shapes. While they are not as common as other leaf shapes, they are still an important feature to note when identifying plants in the wild.
