Học thuậtThân thiện
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
