See if one of the Agoseris species fit.

It seems to be in the scorzonera family , how can I get more details?

You never provided a location. Also curious how you placed your plant in the Scorzonera genus. If that part is accurate, there are only two Scorzonera species in the US. The first is S. hispanica, which is only found in northern California. The second is S. lacinata. That one does look something like your plant, and is found along a line from northwest Montana to the panhandle of Texas. It was also recently found in southern Oklahoma.

Sorry i didn t mention the location
Lebanon mountains, middle east
It is not lacinita
Thank you

The Lebanon Flora site lists nine Scorzonera species. That list is available from the link below. Maybe you can narrow the list by searching online photos, or send them a photo and ask for input. I was unable to find a free dichotomous key for the area.
