Purslane. Andrakli comes from the Greek word andros for 'man' as purslane is supposedly good for boosting the sex drive. Other people call them glistrida 'slippery' because they make people talk too much. Other people call it τρέβλες (trevles) and wish they could get it out of their vegetable garden even though it's supposed to be really, really, really good for you.
