This variable species has been divided into five separate taxa in the past (F. J. Hermann 1964; C. L. Hitchcock et al. 1955–1969, vol. 1), but more recently, most of the variants have not been separated (A. Cronquist et al. 1972+, vol. 6). The Oregon coastal endemic, Juncus nevadensis var. inventus L. F. Henderson) C. L. Hitchcock, is at one extreme of the variation, having only a single head, fairly dark brown tepals 3.5–4.5 mm, anthers only slightly longer than the filaments, and a distinct habitat. The J. mertensianus var. columbianus segregate, however, approaches var. inventus in number of heads, and the other characters are so highly variable in the complex, they cannot be used alone to separate this variety. Therefore, we are not recognizing any infraspecific taxa at this time. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
