In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphyll) at nodes. The main axis of an inflorescence above the peduncle is the rachis, which hosts flowers (as opposed to directly on the peduncle).

A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
Other plants have the bracts subtend the pedicel or peduncle of single flowers. Metatopic placement of bracts include: When the bract is attached to the stem holding the flower (the pedicel or peduncle), it is said to be recaulescent ; sometimes these bracts or bracteoles are highly modified and appear to be appendages of the flower calyx.
Peduncle (botany), a stalk supporting an inflorescence, which is the part of the shoot of seed plants where flowers are formed; Peduncle (anatomy), a stem, through which a mass of tissue is attached to a body Peduncle (arthropods), the base segments of an antenna; Caudal peduncle, in fish, the narrow part of the body to which the tail attaches
The accompanying page—Plant morphology—provides an overview of the science of the external form of plants. There is also an alphabetical list: Glossary of botanical terms. In contrast, this page deals with botanical terms in a systematic manner, with some illustrations, and organized by plant anatomy and function in plant physiology. [1]
The word "pedicel" is derived from the Latin pediculus, meaning "little foot". [2] The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. [3] A pedicel may be associated with a bract or bracts. [4]
In plant taxonomy, which is the study of the classification and identification of plants, the morphology of plant's flowers are used extensively – and have been for thousands of years. Although the history of plant taxonomy extends back to at least around 300 B.C. with the writings of Theophrastus , [ 124 ] the foundation of the modern ...
Many asteraceous plants have bracts at the base of each inflorescence. [6] The term involucre is also used for a highly conspicuous bract or bract pair at the base of an inflorescence. In the family Betulaceae, notably in the genera Carpinus and Corylus, the involucre is a leafy structure that protects the developing nuts.
