Genus Dimocarpus, also known as the longan tree, is a type of fruit tree that is native to Southeast Asia and thrives in subtropical or tropical climates. This fruit tree is characterized by its small, round fruit that is similar in appearance to a lychee, but has a more translucent flesh. There are several synonyms for Genus Dimocarpus, including Euphoria longan, Dimocarpus longan, and Nephelium longan. In China, this fruit is also known as "dragon eye fruit" because of its resemblance to the eye of a dragon. Despite its small size, the longan fruit is packed with nutrients and is widely used in traditional Chinese medicine for its medicinal properties.
