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).

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
Flowers may be directly attached to the plant at their base (sessile—the supporting stalk or stem is highly reduced or absent). [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.
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.
The word scape (Latin scapus, from Greek σκαΎ¶πος), as used in botany, is fairly vague and arbitrary; various sources provide divergent definitions.Some older usages simply amount to a stem or stalk in general, [3] but modern formal usage tends to favour the likes of "A long flower stalk rising directly from the root or rhizome", [3] or "a long, naked, or nearly naked, peduncle, rising ...
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.
1. (of a flower) The period during which pollen is presented and/or the stigma is receptive. 2. (of a flowering plant) The period during which flowers in anthesis are present. Not defined for some cases, such as when pollen is released in the bud. anthocarp
Node: A point of attachment of a leaf or a twig on the stem in seed plants. A node is a very small growth zone. Pedicel: Stems that serve as the stalk of an individual flower in an inflorescence or infrutescence. Peduncle: A stem that supports an inflorescence or a solitary flower. Prickle: A sharpened extension of the stem's outer layers, e.g ...
