Discussion
Populations from around hot springs in the western United States have been treated as Juncus tweedyi, with the remaining populations called J. brevicaudatus, but no morphologic distinction appears to exist between the two taxa. This species was called J. brevicaudatus in the print edition of the Flora of North America; however, that name at the rank of species was published in 1904 so the name J. tweedyi has priority.
