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] A pedicel may be associated with a bract or bracts. [4]

Pedicel (antenna), the second segment of the antenna in the class Insecta, where the Johnston's organ is found Pedicel or petiole (insect) , the stem formed by a restricted abdominal segment which connects the thorax with the gaster (the remaining abdominal segments) in the suborder Apocrita
A spike is a type of raceme with flowers that do not have a pedicel. A racemose corymb is an unbranched, indeterminate inflorescence that is flat-topped or convex due to their outer pedicels which are progressively longer than inner ones.
The specific epithet longipedicellata means 'long pedicel', referring to the flower. [3] Description
Johnston's organ is a collection of sensory cells found in the pedicel (the second segment) of the antennae in the class Insecta. [2] Johnston's organ detects motion in the flagellum (third and typically final antennal segment). It consists of scolopidia arrayed in a bowl shape, each of which contains a mechanosensory chordotonal neuron.
The whole structure enables the insect to move the antenna as a whole by applying internal muscles connected to the scape. The pedicel is flexibly connected to the distal end of the scape and its movements in turn can be controlled by muscular connections between the scape and pedicel. The number of flagellomeres can vary greatly between insect ...
