Definition
Meaning
A species of grass with sharp, stiff, barb-like awns or seed heads that can catch on clothing or fur, resembling the hazards of barbed wire.
A common name for various tough, invasive grasses, especially in Australia and South Africa, known for their irritating, hooked seeds which are problematic for livestock and agriculture. It symbolizes a natural nuisance and an agricultural weed.

Dialectal Variation
British vs American Usage
Differences
The term is rare in both dialects but has slightly more currency in British-linked Commonwealth contexts (e.g., Australia, South Africa). In American English, it would be an exotic, technical term.
Connotations
Connotes a troublesome, invasive plant species, particularly in pastoral settings. Evokes images of the outback, farms, and natural hardship.
Frequency
Very low frequency overall. Most likely encountered in agricultural texts, botanical guides, or regional writing from Australia/Southern Africa.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct calque like *'колюче-проволочная трава'*. It is an established plant name, not a descriptive phrase. Use the specific botanical term or a descriptive phrase like *'трава с колючими семенами'* if the exact species is unknown.
Common Mistakes
- Using it as a general metaphor for something spiky (e.g., 'His beard was like barbed-wire grass'). It's too specific. Confusing it with 'barbed wire' itself. Hyphenation: it is typically hyphenated ('barbed-wire grass').

FAQ
Frequently Asked Questions
Not poisonous, but physically hazardous. Its sharp, barbed seeds can injure animals' eyes, mouths, and skin, degrade wool quality, and contaminate fodder.
No. It is a specific common name for particular species, primarily in the Southern Hemisphere. Using it for other grasses is technically incorrect.
'Wire grass' is a broader, more ambiguous term for various tough, wiry grasses. 'Barbed-wire grass' is more specific, emphasizing the hooked, catching nature of its seeds.
Through integrated methods: strategic grazing management, herbicide application, burning where safe, and promoting competitive pasture species to suppress its growth.
