Tribulus
Scientific name: Tribulus cistoides
Other name: Puncture Vine
The tribulus is a vine that spreads broadly and grows low to the ground. It has small leaves and bright yellow or white flowers.
The seeds of the tribulus are protected inside a spiny shell, with about 5 to 6 seeds in each shell. The spiny pods for the seed are the reason the plant is called "puncture vine."
