#bundle

• Selected bundle — A rare regional term designating the act of choosing or the result of a rigorous selection or sorting; a bundle or bunch of objects or plants manually selected and sorted based on common characteristics. In some ancient craft dialects, the word could also refer to a technological stage in preparing textile threads, where they were structurally grouped by quality.
• Amphicentric — Disposed concentrically on both sides or around a central core; in plant histology and anatomy, it describes a type of fibrovascular bundle where either the woody tissue (xylem) or the phloem completely surrounds the other structural component. Additionally, in neurology or optics, it can refer to fibers or light beams converging or diverging symmetrically around a common focal point.
• Atactostele — A type of stele or central cylinder structure of the stem, characteristic of monocotyledonous plants, in which the vascular bundles are scattered irregularly throughout the ground tissue, without a strict concentric arrangement. As an adjective, it describes a plant stem or vascular system featuring this asymmetric and dispersed anatomical configuration.
