Cirsium ciliolatum

Jump to: navigation, search


Cirsium ciliolatum is restricted to a few sites in and around the Klamath Range of Jackson County, Oregon, and Siskiyou County, California. It is listed by the state of California as endangered. It is closely related to C. undulatum and perhaps should be treated as a variety of that species. Pending a comprehensive study of the variation within C. undulatum, I have maintained C. ciliolatum as a distinct species.
