Ixtle, also known by the trade name Tampico fiber, is a stiff plant fiber obtained from a number of Mexican plants, chiefly species of Agave and Yucca. The principal source is Agave lechuguilla, the dominant Agave species in the Chihuahuan Desert. Ixtle is the common name (or part of the common name) of the plants producing the fiber. Ixtle is also the common name of a species of bromeliad, Aechmea magdalenae, grown in southern Mexico for its silky fibers.
