cypsela
Very LowTechnical/Scientific
Definition
Meaning
A type of dry, single-seeded fruit that does not split open at maturity, characteristic of plants in the daisy family (Asteraceae).
In botany, a small, dry, indehiscent fruit derived from an inferior ovary, often with a crown of hairs (pappus) that aids in wind dispersal. It is the characteristic fruit of sunflowers, dandelions, and related plants.
Linguistics
Semantic Notes
The term is highly specific to botanical taxonomy and morphology. It is often confused with the more general term 'achene', but a cypsela is specifically an achene derived from an inferior ovary, which is the defining feature of the Asteraceae family.

By CEFR Level
- The fluffy part of a dandelion carries its fruit, called a cypsela.
- Botanists distinguish a cypsela from other achenes by its origin from an inferior ovary.
- The papery pappus attached to the cypsela facilitates anemochory, or wind dispersal, in many Asteraceae species.
Learning
Memory Aids
Mnemonic
Think of a 'dandelion's parachute seed' – that's a CYPSELA. Remember: 'Sip' your tea and watch the 'cypsela' fly away.
Conceptual Metaphor
A tiny, self-contained survival pod designed for aerial travel.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with the more common Russian botanical term for a simple nutlet or achene (орешек). 'Cypsela' is a more specific sub-type.
- There is no direct, common one-word translation; it is a learned loanword (ципсела) or described as a specific type of семянка.
Common Mistakes
- Pronouncing it as /saɪpˈsɛlə/ (with a 'y' as in 'cyber').
- Using it interchangeably with all achenes (it is a specific kind).
- Misspelling as 'cypsella' or 'cypsela'.
- Assuming it is a common word.

FAQ
Frequently Asked Questions
No. A cypsela is a type of fruit that contains a single seed. The seed is inside the cypsela.
Generally, no. They are typically small, dry, and fibrous. However, the seeds inside some cypselae, like sunflower 'seeds' (which are technically fruits/cypselae), are edible.
The standard plural is cypselae (/sɪpˈsiːliː/).
It is a highly specialised term from botanical Latin. Most people refer to these structures simply as 'seeds' (e.g., dandelion seeds) or use the broader term 'achene' in general biology.
