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). [1 ...
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
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.

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 ...
The degree of pubescent varies on the peduncle from sparsely to fully hairy, pubescent. The pedicels, the stalk of a single flower, measures up to 8 mm long and is hairy, pubescent. The bracts, modified leaves at the base of a pedicel of a flower, a peduncle, or a branch, are longer than the pedicels on Pachypodium brevicaule Baker. They are ...
For example, the "flower" of the well known Anthurium spp. is a typical spadix with a large colorful spathe. [ 1 ] In this type of inflorescence , peduncle is thick, long and fleshy, having small sessile unisexual flowers covered with one or more large green or colourful bracts (spathe).
