One of the most common species of the commonly named Caltrop, around Alice Springs is Tribulus eichlerianus, which is a native species. One of the best way of identifying it appears to be the fruit, which has a velvet surface (can be described as velvety-hairy) and with prominent, short, median dorsal spines (the arrangement of the burrs is different to that of T terrestris).
It is an important food source for all sorts of parrots.
