Tribulus terestris
Noun 1. A specific plant species: A low-growing, annual, tropical or subtropical plant belonging to the caltrop family (Zygophyllaceae). It is characterized by its prostrate (procumbent) growth habit, small yellow flowers, and hard, spiny fruit that splits into five sections. It is considered a problematic weed in pastures and grasslands.
- As a common name: The term is used as the scientific and formal common name for this specific plant species.
- Example: The field was overrun with Tribulus terestris, making it difficult for the animals to graze.
- In agricultural or botanical contexts: Used when discussing pasture management, invasive species, or plant biology.
- Example: Farmers must control Tribulus terestris to prevent injury to livestock from its spiny fruits.
- In pharmacological or supplement contexts: While the primary definition refers to the physical plant, extracts from a related species () are used in traditional medicine and dietary supplements. Note the slight spelling difference ( vs. ).
- Example: Some athletes use extracts derived from Tribulus species for their purported effects.
- Puncture vine: A widely used common name for this plant, referring to the fruit's ability to puncture tires and animal feet.
- Caltrop: A general name for plants in the genus, and also a term for a spiked weapon, drawing a direct analogy to the plant's spiny fruit.
- Goat's-head: Another common name in some regions.
- Tribulus terrestris: The correct and more commonly used scientific name for the species often referred to colloquially as "tribulus terestris". "Terestris" is a frequent misspelling of "terrestris".
- Puncture vine
- Caltrop (in botanical context)
The entry "tribulus terestris" appears to be a common misspelling or variant rendering of the standard scientific name Tribulus terrestris. All defining characteristics (procumbent, poisonous, spiny nutlets, pasture weed) apply to Tribulus terrestris L. The primary meaning is the plant itself as a biological entity and an agricultural pest. Any references to its use in supplements are secondary and apply to the correctly named species.
- tropical annual procumbent poisonous subshrub having fruit that splits into five spiny nutlets; serious pasture weed
