Umbulate Hawkweed

I finally got out with friends for an almost three-hour botany walk in the afternoon of 11 August 2015, at Griffith Woods. There were certain "target" plants on the list, including three species of wild Gentian and one species of Orchid (Rattlesnake Plantain). We had success with all four, which made for a successful outing. There was also a patch of beautiful wild Sunflowers, which I always enjoy seeing year after year. They are sometimes called Common Tall Sunflower, as well as Nuttall's Sunflower. Also this Umbulate Hawkweed, which, I find, can be easily confused with Sowthiste flowers. For this year, wildflowers are now finished - always a depressing thought.
