[BONAP county map]
Discussion

Coastal dunes, shores, sandy swales, springs, cranberry farms, ditches. 0–50m. Est, Sisk. CA, WA; north to British Columbia. Native.

The peculiar leaves of this taxon are usually flattened but hollow and completely septate, which helps separate it from J. phaeocephalus, a California species with iris-like leaves that are solid and incompletely septate. Juncus phaeocephalus has been reported in error from Oregon several times.
