never seen leaves without tissue
 

hello global specialists,

since half a year, a french friend and me are looking for the name of
this surprisingly strange plant, found in a suburbian garden, but being
stolen before coming to bloom
has anyone any suspicion what it could be, leaves in form of open grid,
i. e. veins without flesh
in what direction should I browse at Google, I have tried all, and read
all my books about plant families - the nearest bet was thistle, silybum
marianum

you know, the worst thing for a botanist is not finding the name

thanks for any endeavours
