Longan, or dragon's eye, is native to China and from India to the Philippine Islands. It reaches a height of 50 feet, with a trunk 2.5 feet in diameter. The leaves measure up to 1.5 feet long and are composed of up to ten leaflets with wavy margins, the largest up to 9 inches long. Flowers are small and are grouped in erect terminal inflorescences. Fruits are up to 1 inch wide and are grouped in bunches. It flowers during spring and summer, and fruits mature during summer and fall. The generic name means double fruit, apparently in reference to the flower's two-lobed pistil. The species name means dragon eyes, in reference to the appearance of the peeled fruit.

The photographed tree is one of three specimens planted north of the new Agricultural Sciences greenhouses, these are the only members of the species in the campus.
