Meaning
A tall, columnar cactus (Cephalocereus senilis) characterized by long, white, hair-like spines that resemble an old man's beard.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation 'старый мужчина кактус'. The correct Russian botanical term is 'Цефалоцереус старческий' (Cephalocereus senilis) or the descriptive 'кактус 'старик''.
- The hyphen is crucial in English to show it's a single compound noun.
Common Mistakes
- Writing as three separate words ('old man cactus').
- Confusing it with other hairy cacti like Espostoa lanata (Peruvian old man).
- Using it as a metaphor for an actual elderly male.
