drosera
LowScientific/Technical
Definition
Meaning
A genus of carnivorous plants, commonly known as sundews, that trap insects using sticky glandular hairs on their leaves.
Any plant belonging to the genus Drosera, characterized by rosettes of leaves covered in tentacle-like stalks tipped with mucilage to capture prey, found in nutrient-poor soils worldwide.
Linguistics
Semantic Notes
The term is almost exclusively used in botanical contexts. It is a proper noun (genus name) but often used as a common noun to refer to individual plants. The common name 'sundew' is far more frequent in general usage.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. Both varieties use the Latin botanical name identically.
Connotations
None beyond its technical botanical reference.
Frequency
Equally rare in both varieties outside specialized contexts.

Examples
By CEFR Level
- This plant is called a sundew.
- The sundew is a small plant that catches insects.
- Several Drosera species are native to this boggy habitat, where they supplement poor soil nutrients by trapping insects.
- The phylogenetic study focused on the evolution of trapping mechanisms within the genus Drosera, comparing glandular morphology across three continents.
Learning
Memory Aids
Mnemonic
DROSERA traps prey with ROSy dew. Think: 'Dewy ROSes are sticky' – but it's a carnivorous plant.
Conceptual Metaphor
N/A (Highly technical term with little metaphorical extension.)
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'роса' (dew) alone; the full term 'росянка' is the correct equivalent.
- It is a proper scientific name, so transliteration 'дрозера' is incorrect in common language.
Common Mistakes
- Mispronouncing as /droʊˈsɪrə/ or /ˈdrəʊzərə/.
- Using it as a common noun in everyday conversation instead of 'sundew'.
- Capitalizing it inconsistently (should be capitalized as a genus name).

Frequently Asked Questions
No, they are different genera of carnivorous plants. Drosera (sundews) use sticky tentacles, while Venus flytraps have hinged leaves that snap shut.
In strict botanical writing, it should be capitalized as it is a genus name (Drosera). In informal contexts referring to the plants generally, lowercase is sometimes seen but not technically correct.
They require high humidity, distilled or rainwater (not tap water), bright light, and nutrient-poor soil like peat moss. They do not need fertiliser as they get nutrients from insects.
The common name 'sundew' comes from the glistening, dew-like drops of mucilage on its tentacles, which sparkle in the sun.
