Discussion
Xerophyllum tenax, variable in plant and flower size, is without evident geographic races (S. M. Maule 1959). Similar in most respects to X. asphodeloides but more robust, X. tenax typically has twice the number of flowers (F. H. Utech 1978c). The leaf fibers were used by native tribes for garments and decorative, watertight baskets. The bulbous rhizomes were roasted for several days before being eaten.
