In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). They are primarily found among dicots and rare among monocots.

The following points highlight the ten main types of stipule present in a plant. The types are: 1. Lateral 2. Adnate 3. Scaly 4. Intrapetiolar 5. Interpetiolar 6. Foliaceous 7. Ochreate 8. Spinous 9. Tendrillar 10. Ventral. Stipule in a Plant: Type # 1. Lateral: Present laterally on or at the side of the base of petiole, e.g., Hibiscus.

2023年8月9日 · Stipulate meaning: Stipulate typically refers to a specific feature or characteristic of a plant’s leaf. While stipules can be found singly or in pairs depending on the plant species, their position is fixed, i.e. on the base of the petiole. Stipulate leaves can have stipules in varied sizes, shapes, and textures.

2024年1月17日 · Stipules are widely found in angiosperms with a high level of diversity, and they may be considered as a significant feature of the flowering plants (De Candolle 1827, Goebel 1905, 1933, Sinnott and Bailey 1914, Troll 1939, Mitra and Majumdar 1952, Napp-Zinn 1974).

Stipules are foliar appendages at the base of the leaf sheath or hypopodium that are often paired and sometimes leafy. They may range from quite leaf-like to small and inconspicuous structures. They are typically regarded as a component of a normal flowering plant’s anatomy. Stipules, however, are not present in a lot of plants.

This family, with ∼75 genera of shrubs and trees, is one of the most diverse in the Southern Hemisphere. The plants are characterized by exstipulate leaves, four-merous flowers in the form of a raceme, with paired, unisexual or bisexual flowers, each with a single carpel and fewer than eight ­stamens. Petals are typically absent.

Stipules, a pair of appendages subtending the leaf petiole, are usually present. …the families in the order, stipules are diminutive, only rarely reaching a length of more than a few millimetres; they are absent in Combretaceae, Onagraceae, and Melastomataceae.

Flowers: Yellow pea flowers up to 1cm long with faint red markings on standard and borne in dense terminal clusters. Flowering: August-October. Fruit: A swollen pod 6-7mm long. Leaves: Alternate, narrow, linear 1.5-2.5cm long and 1-2mm wide, concave and sharply tapered and crowded along stem with large rusty-brown 1cm long stipules.

This study aims to determine the morphology and anatomy characteristics of the stipules in seven plants. The research was conducted in November 2023 – January 2024 at the Biology Education Laboratory, Sriwijaya University.

Stipules are leaf structures common in many groups of plants that can take a variety of forms. In Gentianales, interpetiolar stipules are considered a synapomorphy of Rubiaceae but in this study we detected two lateral expansions at the base of the leaf primordia (stipules) that give rise to colleters in many genera of Apocynaceae, similarly to ...
