"Dimocarpus longan, commonly known as the longan, is a tropical tree species that produces edible fruit. It is one of the better-known tropical members of the soapberry family Sapindaceae,to which the lychee and rambutan also belong. The fruit of the longan is similar to that of the lychee, but less aromatic in taste."
