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 petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile.
The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; [1] [2] while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders.
Pedicle of vertebral arch, the segment between the transverse process and the vertebral body, and is often used as a radiographic marker and entry point in vertebroplasty and kyphoplasty procedures; Pedicle of a skin flap (medicine) Hilum of kidney, also called the renal pedicle; Pedicel, a foot process of a some cells
Petiole – a leaf stalk supporting a blade and attaching to a stem at a node. Petiolule - the leaf stalk of a leaflet. Pulvinus – the swollen base of a petiole or petiolule, usually involved in leaf movements and leaf orientation. Rachilla – a secondary axis of a multiply compound leaf. Rachis – main axis of a pinnately compound leaf.
Having leaf tissue taper down the petiole to a narrow base and always having some leaf material on each side of the petiole auriculate: auriculatus: leaf base: Having ear-shaped appendages reaching beyond the attachment to the petiole or stem (in case of a seated leaf) caudate: caudatus: leaf tip: Tailed at the apex cirrus, cirrate: leaf tip
The vascular cambium forms between the xylem and phloem in the vascular bundles and connects to form a continuous cylinder. The vascular cambium cells divide to produce secondary xylem to the inside and secondary phloem to the outside. As the stem increases in diameter due to production of secondary xylem and secondary phloem, the cortex and ...
The collective term for the segments between the club and the antennal base is the funicle; traditionally in describing beetle anatomy, the term "funicle" refers to the segments between the club and the scape. However, traditionally in working on wasps the funicle is taken to comprise the segments between the club and the pedicel. [10]
