JUST A WEED

Some people take weeds seriously, this plant (weed) grows all over La Isla Tranquila (Fuerteventura) hope we do not get any over here.

What do you reckon it is? Euphorbia rotunda? :-D

No, very descriptive, but I think it may be a Notoparking underii Giganticus

Poor thing, looks like all it's leavess have fallen off!

Just as it grows in life no leaves like most cacti
