Additional close-ups of sagebrush agoseris as seen along the North Loop Road about one-half mile uphill from Jackman Park or across from the south fork of the uppermost section of McCoy Creek, Steens Mountain, Harney County, Oregon................August 31, 2011. Note on the seed head that the beak (the narrow shaft that connects the achene or seed to the umbrella-like plume) for this species ranges from about one-half to equal the length of the achene, which helps identify this species. Because a few of both Agoseris x agrestis and Agoseris monticola are present nearby, some of the plants present here seem to show some characteristics of the others.
