Plants show three types of phyllotaxy- alternate, opposite and whorled types of phyllotaxy. Leaf base has two small leaf-like structure called stipules. Some stipules … If the stipules are absent, the lea F is called ex-stipulate. There are 4 types of tendrils as, Leaves may get modified into tendrils as in Pisum sativum where the apical leaves are modified into tendrils. The main difference between stipules and bracts is that stipules are the leaf-like structures present on the leaf base, but bracts are the leaf-like structures present on the base of the inflorescence. Stipules. The three types of stipules according to duration are caducous, deciduous and persistent. Types of Stipules: Stipules may be classified into the following three types based on the duration for which they remain attached to the leaf base: 1. KINDS OF STIPULES-There are several kinds of stipules, viz :-(i) free-lateral, (ii) adnate, (iii) intrapetiolar, (iv) interpetiolar, (v) ochreate, (vi) foliaceous, (vii) tendrillar, (viii) spinous and (ix) bud scales. There are three main tissues found in leaves: the epidermis, the mesophyll, as well as vascular tissue. Caducous: The paired stipules, when present, are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.… This type of violet grows throughout most of the northeastern United States, and it blooms from early to late spring. Pair or ootarowths developed at the base of the petiole of a leaf are called stipules. They are short-day legumes that begin flowering in late August and set seed in mid-September to mid-October. . Both annual and perennial types grow in a soil pH range of 4.5–7.0. Leaves can have different shapes and sizes. Leaves with stipules are called stipulate and those without are called exstipulate. The stipules may be either attached to the leaf base or are present on both sides as lateral outgrowths. When managed properly, annual lespedeza can re-seed itself. Types of Lespedeza Annual. Stipules are present in many angiosperm plants. It has unusual leaves with blades that taper near the stalks and with stipules that divide into lobes that are very narrow. Types According to duration. According to shape, size and position The petals, which are irregular in shape, are usually either blue or white and they have yellow markings. Each tissue type … Furthermore, stipules are parts of true leaves while bracts are a type of modified leaves being part of the inflorescence. The basic components of leaves in flowering plants (angiosperms) include the blade, the petiole, and the stipules. (i) Free-lateral stipules-These are tiny slender free outgrowths on both sides of the petiole at the base. In plants like paddy, wheat, and other monocotyledons, this leaf base is wide and masks the stem. The leaf base is the slightly expanded area where the leaf attaches to the stem. the leaf is called stipulate. Persistent stipules remain attached to the plant. Hooks. In some plants like Lathyrus aphaca, the entire leaf gets modified into a tendril and the stipules expand to carry out the function of a leaf. A structurally complete leaf of an angiosperm consists of a petiole (leaf stalk), a lamina (leaf blade), stipules (small structures located to either side of the base of the petiole) and a sheath.Not every species produces leaves with all of these structural components.
