Another Asteraceae, we would like to know the name please
Sonchus oleraceus L. ??

Thanks, ..., for the initial id.
Sonchus asper is more likely (if found there) rather than Sonchus oleraceus

OK ...!

It could be other sp. also but S. oleraceous looks like ntroduced as mentioned in some google 
By the way S. wighitianus and S. afrvensis is found listed but does not look matching.
