Note 13 — XXIV
Reading edition
In the Agricultural Report of 1869, p. 232, another fiber was highly mentioned, belonging to a plant very closely related to sisal (Bromelia Sylvestris), perhaps even a variety of the same. The Mexican name, jxtle, is possibly derived from the fact of their curiously flattened, spike-edged leaves, resembling the dentated knives formed from volcanic stone (obsidian) possessed by the Aztecs and termed by them iztli.
