Discussion

Damp dunes, sandy shores, coastal fresh-water marshes. 0–50m. Est. CA. Native.

This species is identified by the large flowers typical of J. breweri and the more open inflorescence found in J. balticus. It is possibly derived from hybrids between those two species and often grows with them. It was long thought to be endemic to the San Francisco Bay area (Lint 1977).
