It's all about an issue with synonyms. It happened with Salvia lanceolata. I was about to upload my photos but the entry it was going to had it as a synonym AND there was one photo of the proper plant, a Texas native with blue flowers and the rest were of those the same as mine. I had to wait quite some time before catolouge of life cleared that up and S. lanceolata had its own entry in the DB. As for the Star Thistle....it is a viscous thing. It's from here in the valley and all the way along the highways all over and up to at least three thousand feet into the foothills. A real threat to natives due to its thickness. Now your flower has its own space, in the DB for now.
