Taxonomic Comments

Kartesz (1994, 1999) recognized Juncus ensifolius in a sense that included J. xiphioides var. triandrus, but did not include J. saximontanus and J. tracyi. In contrast, Flora of North America Editorial Committee (2000) places J. xiphioides var. triandrus in J. ensifolius var. montanus, along with J. saximontanus and J. tracyi.
