Definition

Noun: A leaf whose margin (outer edge) is characterized by having numerous sharp, stiff points or spines.

Usage

This is a specific botanical term used to describe the physical characteristic of a leaf's edge. It is typically used in scientific, horticultural, or descriptive natural contexts.

Examples

• The holly plant is easily identified by its prickly-edged leaf.
• Botanists noted that the specimen had a prickly-edged leaf, unlike the smooth-edged leaves of its close relatives.
• Handling the plant requires care due to its prickly-edged leaves.

Advanced Usage

• The term is often used in dichotomous keys for plant identification, where the presence of a prickly-edged leaf is a distinguishing feature that separates one species from another.
• It can be used descriptively in ecological studies: "The adaptation of a prickly-edged leaf may deter herbivores."

Variants and Related Words

• Prickly: (Adjective) Covered with or full of prickles.
• Serrated leaf: A leaf with a margin that has sharp, forward-pointing teeth (like a saw). This is a related but distinct type; serrations are typically smaller and more regular than the prickles on a prickly-edged leaf.
• Spiny leaf: A very similar term, often used interchangeably, though "spiny" may imply larger, more pronounced spines.

Synonyms

• Spiny-edged leaf
• Thorny-margined leaf

Antonyms

• Smooth-edged leaf
• Entire leaf (a botanical term for a leaf with a smooth, uninterrupted margin)

Noun

1. a leaf having prickly margins
