Dimocarpus longan
リュウガン
An evergreen small tree in the soapberry family. Native to southern China and Southeast Asia. The fruit — 'longan' or 'dragon eye' — is named for the translucent white flesh that wraps a dark seed, resembling a dragon's eye. Related to lychee but milder in flavor. The dried fruit is used in Chinese medicine as 'ryūgan-niku'.
