I always thought corinader and cilantro were different-your post prompted me to ask "uncle google" and here is what he said-
After the plant flowers and develops seeds, it is referred to as coriander. Cilantro (sih-LAHN-troh)is the Spanish word for coriander leaves. It is also sometimes called Chinese or Mexican parsley. Technically, coriander refers to the entire plant.

 

Another fun fact is that cilantro is call "wansoy" here. If you were like me and assumed that cilantro simply didn't exist here, it's possible that you weren't looking for the correct label. You can often find wansoy in Robinson's, but Naturally Negros is another good source from what I have heard (I have never been there myself).
