Tribulus macrocarpus is a species of flowering plant in the family Zygophyllaceae, which is found to the central north of Western Australia, and southern inland Northern Territory and northern South Australia.[1] [2]
It was first described by George Bentham in 1863 from a specimen collected by Francis Thomas Gregory from Nicol Bay. An holotype (K000725223) collected by Gregory is held at Kew.[3] The specific epithet, macrocarpus, is derived from two Greek roots/words, macro- ("large", "great") and -carpus, ("-fruit" / "-fruited"), and describes the plant as having large fruits.[4]
Under West Australian conservation laws it is deemed to be "not threatened".
