In some plants we can see lateral small-leaf like structure at the leafbase.When the leaf is a bud stipules protect the bud as a cover.Later ,it changes into thorns or stay without change.
Yes, you can find stipules in Hibiscus rosa-sinensis (gumamela) leaves, while grasses typically lack stipules. Stipules are small leaf-like structures found at the base of a leaf stalk or petiole in some plants.
Not every leaf has its own stipule. Stipules are small leaf-like structures that can be found at the base of some leaves, but their presence varies among different plant species. In some plants, leaves may emerge without stipules, while in others, stipules can be prominent or even modified into spines or tendrils. The presence and form of stipules are specific to the plant's evolutionary adaptations.
Stipules are small leaf-like structures that can be found at the base of a leaf stalk (petiole) in some plants. In gumamela (Hibiscus rosa-sinensis), stipules are typically paired, and they can vary in shape and size. They may serve protective or supportive roles for the young leaves and buds as they develop. However, in many hibiscus species, the stipules are often small and may not be very noticeable.
Modified leaf or stipules
Leaf tendrils originate either from stipules or leaflets whereas the stem tendrils are modification of axillary buds representing the stem branches.

Stipules of papaya are small, leaf-like structures that are typically found at the base of the petiole (leaf stem) in the papaya plant (Carica papaya). In many cases, these stipules are ephemeral and may fall off as the plant matures. They play a role in protecting the young leaf during its development. While they are not prominent, their presence is a characteristic feature of the papaya's leaf structure.

Modified leaf or stipules
A simple leaf has a flat, thin structure with a main vein running through the center. It typically consists of a blade, petiole, and stipules. The blade is the main part of the leaf where photosynthesis occurs, while the petiole connects the leaf to the stem. Stipules are small, leaf-like structures at the base of the petiole.
In some plants we can see lateral small-leaf like structure at the leafbase.When the leaf is a bud stipules protect the bud as a cover.Later ,it changes into thorns or stay without change. There aren't any obvious functions of the stipule. It may have been involved in protecting emerging leaves. Some stipules appear to protect the buds. Stipular spines may serve as protection for the plant by keeping it from being eaten. Sipular spines in some plants serve as a home for ants.
Each leaf typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
Leaf tendrils originate either from stipules or leaflets whereas the stem tendrils are modification of axillary buds representing the stem branches.
In botany, stipule (Latin stipula: straw, stalk[1]) is a term coined by Linnaeus[1] which refers to outgrowths borne on either side (sometimes just one side) of the base of a leafstalk (the petiole). A pair of stipules is considered part of the anatomy of the leaf of a typical flowering plant, although in many species the stipules are inconspicuous or entirely absent (and the leaf is then termedexstipulate).In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.Stipules are morphologically variable and might appear as glands, scales, hairs, spines, or laminar (leaf-like) structures. A relationship exists between the anatomy of the stem node and the presence or absence of stipules. Most plants with trilacunarnodes have stipules; species with unilacunar nodes lack stipules (Sinnott and Bailey, 1914, cited in Esau, 1953).By. fan of Chicser ( GEllo )

The leaf base provides structural support and attachment for the leaf to the stem. It also helps in transporting water and nutrients between the leaf and the stem. Additionally, the leaf base may contain specialized structures like stipules or tendrils that serve various functions depending on the plant species.
