As a comment about Scorzonera intricata
Hi to all of my friends in All Thing Plants. I am Dr. S. Azadi and it's been about 30 years that I have worked in the natural resources agency of Isfahan-Iran. Research about plants is my first interest and I have a huge archive of Iran plants (I am a professional photographer too.). If I can help you, it's my pleasure. I have uploaded three pictures of Scorzonera intricata to your entry. I searched all of the floristic sites and I could not find any pictures of this species, so I think the relationship between us can help for better world information about plants.
