Definition
Noun: 1. A small cup-shaped anatomical structure: A biological term for a small, cup-like formation in certain organisms, such as a taste bud, the optic cup in the eye, or the cavity in a coral that houses a polyp. 2. An epicalyx; a group of bracts resembling a calyx: In botany, a ring of small, leaf-like structures (bracts) located just below the true calyx (the whorl of sepals) of a flower, giving the appearance of an extra calyx.
Usage Examples
- The tiny calycle of the coral provides a protective home for the polyp.
- Botanists noted the presence of a distinct calycle beneath the flower's sepals.
- Under the microscope, the structure resembled a calycle.
Advanced Usage
- The term is highly specialized and used almost exclusively in scientific contexts (botany, zoology, anatomy).
- It is often synonymous with "epicalyx" in botanical descriptions.
- In some older texts, "calycle" may be used interchangeably with "calyculus."
Variants and Related Words
- Calyculus (noun): A direct synonym, often used in anatomical contexts (e.g., calyculus of a taste bud).
- Epicalyx (noun): The preferred botanical term for the ring of bracts simulating a calyx.
- Calyx (noun): The main whorl of sepals forming the outer part of a flower, which the calycle/epicalyx may resemble or supplement.
Synonyms
- For anatomical sense: calyculus, cupule, small cup.
- For botanical sense: epicalyx, false calyx.
Notes on Meaning
This word has two distinct, domain-specific meanings: 1. Biological/Anatomical Sense: Refers to a small, cup-shaped cavity or receptacle. 2. Botanical Sense: Refers specifically to an accessory structure made of bracts that looks like an extra calyx.
Noun
