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]
According to Guinness the pedicel of the H. whipplei inflorescence can grow up to ten inches (25 cm) a day towards an eventual height of 11ft 11in (3.65 meters) [6] The plant takes several (usually 5+) years to reach maturity and flower, doing so in April–May, [5] at which point it usually dies.
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
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]
Female flowers are on a short pedicel, the petals 2.0–2.3 mm (0.079–0.091 in) long and densely hairy carpels with 1 ovule per locule and 3 styles. The fruit has up to 3 follicles 6–15 mm (0.24–0.59 in) long and 5–10 mm (0.20–0.39 in) long and joined at the base, each containing a single seed.
The flowers are fragrant and are arranged in loose groups, each flower on a pedicel 1–1.5 mm (0.039–0.059 in) long. There are five (sometimes four) sepals about 1 mm (0.039 in) long and five (sometimes four) white or cream-coloured petals 13–18 mm (0.51–0.71 in) long. and the fruit is an oval, glabrous, orange-red berry 12–14 mm (0.47 ...
The egg of Paracantha gentilis has a long, opaque pedicel that is about twice the size of the egg body; [7] this character is shared with other Paracantha species such as Paracantha trinotata. [8] This pedicel is tubelike, and is always exposed to outside air when oviposited, presumably for respiration. [7]
The flowers are arranged in umbels 12–13 mm (0.47–0.51 in) in diameter of about 14 flowers on a peduncle about 70 mm (2.8 in) long, each flower on a pedicel 16–18 mm (0.63–0.71 in) long. The petals are wheel shaped, fleshy pale pink to white with triangular lobes 4–5 mm (0.16–0.20 in) long and about 5 mm (0.20 in) wide.
