Etymology: From 1886 French stèle, from Ancient Greek στήλη (stḗlē, “upright rock; pillar; column”).

  1. The central core of a plant's root and stem system, especially including the vascular tissue and developed from the plerome.

    “The stele may have—in different structures—one to many protoxylem (primitive wood) groups, and is accordingly described as monarch...diarch...triarch...tetrarch...polyarch.”

    “The so-called central cylinder, for which Van Tieghem has proposed the name stele (column).”
