Does look a lot like C.microcephalum, Barb are you happy with this ID or is there something we are both missing? I know Cullen tenax has been recorded from this location before.
Hi Barb I think all Cullen we saw at Wildflower Patch 1 yesterday were C microcephalum; check nearby sightings of Cullen tenax. The site has changed very much since last year as we observed for instance much more grass and Sticky Everlasting.
