cobweb thistle ~ 05/14/11 ~ Fort Ord

cobweb thistle
Cirsium occidentale

According to Jepson Online Interchange, there are 7 native varieties of cobweb thistle found in California. Two of those, C. occidentale var. occidentale (cobweb thistle) and C. occidentale var. venustum (venus thistle), are recorded for Fort Ord by the California Native Plant Society. Without the flower I have no clue as to which variety this one is. Quite honestly, while I reference Jepson as I search for information, I don't really understand its descriptions when distinguishing between closely related plants. Several of these thistle were found in a 2009 burn area.
