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]
The scape and pedicel generally comprise a single segment each. The antennal formula is used to describe the number of segments in each of the components of the antenna (scape; pedicel; anelli, funicle; clava). An antennal formula of 1:1:2:4:3 indicates an antenna with a scape, a pedicel, 2 anelli, 4 funicular segments, and 3 segments in the ...
The specific epithet pedicellatum is from the Latin, referring to the long pedicel (flower stem). [2] Description.
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
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.
The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres. [10] The pedicel (the second segment) contains the Johnston's organ which is a collection of sensory cells. [11]
According to electron microscopy studies, antennae are composed of sections called a scape, a pedicel, and nine flagellomeres, which are used for movement of the antennae. [7] However, the antennae are pectinate, or narrow, in males, while, in females, the antennae are serrate, or thicker and notched. [ 2 ]
The flowers are perched on a pedicel (i.e., flower stalk) raising them above the leaf whorl, and grow pinker as they age. [9] [10] The flowers' stigmas are slender, straight or mostly so, narrowing at the end. [6] The white petals are much longer than the green sepals. [6] The flowers have six stamens in two whorls of three, which persist after ...
