Forum Flora Germanica

How come one cant find any subsp. var. name for this:
"Puntarelle,Italian dandelion,Catalogna a foglie frastagliate,Cicoria asparago,Cicoria di catalogna,Katalonski radič"

I guess it is much different than weed found beside roads.

I could only find this paper of unknown quality from the Links section in the German "Rumor"-pedia for "Puntarella":

The author claims it has been overlooked by science so far and hasn't been formally described.
