Contrast with peduncle of Agave. 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 cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the ...
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
A flower that is not part of an inflorescence is called a solitary flower and its stalk is also referred to as a peduncle. Any flower in an inflorescence may be referred to as a floret, especially when the individual flowers are particularly small and borne in a tight cluster, such as in a pseudanthium.
[2] [25] The stem or stalk subtending a flower, or an inflorescence of flowers, is called a peduncle. If a peduncle supports more than one flower, the stems connecting each flower to the main axis are called pedicels. [2] [26] The apex of a flowering stem forms a terminal swelling which is called the torus or receptacle. [2] [24]
In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. 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]
Pedicel – the stem or stalk that holds a single flower in an inflorescence. Peduncle – the part of a stem that bears the entire inflorescence, normally having no leaves, or the leaves having been reduced to bracts. When the flower is solitary, it is the stem or stalk holding the flower. Peduncular – referring to or having a peduncle.

Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
