Definition

Noun: 1. The woody stem of palms and tree ferns: A solid, persistent, and often unbranched stem, characteristic of plants like palms and some ferns, which is not a true trunk but functions similarly. 2. The persistent, thickened stem of a herbaceous perennial plant: A short, thickened, often underground stem that serves as a storage organ and a base from which new growth emerges each season, as seen in plants like peonies or some grasses.

Usage Examples

• The botanist pointed out the rough texture of the palm's caudex.
• The plant stores water and nutrients in its swollen caudex to survive the dry season.
• When repotting, be careful not to bury the caudex too deeply.

Advanced Usage

• In botanical terminology, a caudex is distinguished from a corm or tuber by being a stem base, not a modified stem structure.
• The term is often used in horticulture to describe the prized, sculptural base of cultivated succulent plants like (Desert Rose).

Variants and Related Words

• Caudiciform (adj): Having the form of or resembling a caudex.
  • The caudiciform plant was a striking addition to the rock garden.

Synonyms

• Stem base
• Stock (in botanical context)
• Lignotuber (for some woody, fire-resistant types)
