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
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.
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 Forked; cut in two for about half its length. Compare trifid. bifoliate
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 ...
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).
This article lists the living orders of the Viridiplantae, based primarily on the work of Ruggiero et al. 2015. [1] Living order of Lycophytes and ferns are taken from Christenhusz et al. 2011b [2] and Pteridophyte Phylogeny Group. [3]
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 ...
