Cenchrus longispinus

Cenchrus longispinus is a species of grass, also known as spiny burr grass or gentle Annie. Its fruits are clumped into "burrs" with sharp, barbed spines that can penetrate the hides and mouth of grazing animals. They can also become lodged in human clothing, causing some discomfort.[3]
