Discussion

Agave lechuguilla is the principal source of “istle” or “ixtle,” a hard fiber used for rope and known by the trade name “Tampico fibre.” The plant is poisonous to cattle, goats, and sheep. This species is the dominant agave on the Chihuahuan Desert. It hybridizes with A. havardiana, A. neomexicana, A. gracilipes, and A. ×glomeruliflora.
