Tribulus terrestris

Son los frutos de Tribulus terrestris, también llamado "pinchabicicletas" o "abrojos", una planta rastrera común en caminos y terrenos baldíos. El fruto es muy característico con sus espinas laterales y, cuando madura y adquiere toda su dureza, es capaz de perforar neumáticos.

They are the fruits of Tribulus terrestris, also called “puncturevine”, a creeping plant usually found on tracks and waste lands. The fruit is very characteristic with side spines and when it is ripe and has acquired all its hardness it is capable of puncturing tires.
