This species and the next (Juncus ensifolius) are closely related and have been treated as members of a single species (J. xiphioides) by Engelmann. Until a study of the complete subgenus is done, we are hesitant to use a varietal name (J. xiphioides var. triandrus) for the widespread western taxon J. ensifolius.
