In botany, the petiole (/ˈpiːtᵻoʊl/) is the stalk that attaches the leaf blade to the stem. The petiole is the transition between the stem and the leaf blade. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves lacking a petiole are called sessile or epetiolate.
The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk (petiole) may be long, as in the leaves of celery and rhubarb, short or completely absent, in which case the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves are nearly petiolate, or have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus Veronica, petiolate and sessile leaves may occur in different species.
In the grasses (Poaceae) the leaves are apetiolate, but the leaf blade may be narrowed at the junction with the leaf sheath to form a pseudopetiole, as in Pseudosasa japonica.

Jerry Konanui documents the variety of taro known as lauloa ke‘oke‘o using the list of plant descriptors found in “Descriptors for Taro – Colocasia esculenta,” published by the International Plant Genetic Resources Institute. From documenting the position and size of the leaf, to matching the colors of the leaf sap, petiole and corm flesh with botanical color charts, dozens of descriptors are recorded. Along with the scientific documentation, Jerry relates cultural and historic information regarding this variety. His goal is to document as many of the Hawaiian taro varieties as possible for reference by future generations of taro growers. Mahalo to Kent Whealy and Judy Kern for supporting this online series.

In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape that is used by climbing plants for support, attachment and cellular invasion by parasitic plants, generally by twining around suitable hosts. They do not have a lamina or blade, but they can photosynthesize. They can be formed from modified shoots, modified leaves, or auxiliary branches and are sensitive to airborne chemicals, often determining the direction of growth, as in species of Cuscuta.

What is PEDICEL? What does PEDICEL mean? PEDICEL meaning, definition & explanation. A pedicel is a stem that attaches a single flower to the inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

In botany, the term is most often applied to leaf blades that partly wrap or have wings around the stem or petiole and extend down along the stem. A "decurrent branching habit" is a plant form common for shrubs and most angiosperm trees, contrasted with the excurrent or "cone-shaped crown" common among many gymnosperm...
