Linear leaf is a term used to describe leaves that are long, narrow, and flattened, with parallel veins. Other plant terms that refer to linear leaves include lanceolate, which describes leaves that are tapering to a point at both ends, and oblong, which refers to leaves that are longer than they are wide and have rounded ends. Needle-like leaves, like those found on evergreen trees such as pine and fir, are also linear in shape. Additionally, grasses and sedges often have linear leaves that are called blades. Regardless of the term used, the linear leaf is a common and identifiable feature of many plants.
