Plant part

Stipule [ˈstɪpjuːl]

Definition:

A stipule may grow when a new node is developed. Stipules on other plants, such as roses, typically take the appearance of thorns. These serve to defend the plant from pests. They resemble a tiny dagger in the marijuana plant yet are entirely safe. Stipules are unknown in function, but they may be there to shield newborn leaf shoots.
