(Not Listed or Proposed under the Endangered Species Act)
The species name refers to its flattened, spirally twisted flowering stems. This species was published in the scientific literature in 2001, so is not yet in the standard print floras of California; but it is included in the recently published Flora of North America. Photo by Linnea Hanson.
