|discussion=<p>Populations from southern California with brown tepals, anthers equaling filaments, and rounded to acute, translucent auricles have been separated as <i>Juncus</i> duranii; the typical form is so highly variable, however, that it can easily accommodate this local form. This species passes into <i>Juncus nevadensis</i> and has often been combined with that species (F. J. Hermann 1964). The two species can generally be separated, and we are following those treatments (F. J. Hermann 1975; A. Cronquist et al. 1972+, vol. 6).</p>
