|discussion=<p><i>Tribulus cistoides</i>, native to tropical and subtropical southern Africa, is occasionally grown in sandy soils as a garden ornamental or along roads to stabilize shifting soils (D. M. Porter 1972). Although <i>T. cistoides</i> has been reported from Texas, no specimen has been seen and it apparently does not occur there. The species has been introduced to the Galápagos Islands, but not to mainland Ecuador.</p>
