　　Longan (scientific name: Dimocarpus longan Lour.), also known as "Guiyuan" or "Yizhi", is an evergreen tree, usually growing over 10 meters tall. Its branches are sturdy, covered with fine hairs, and scattered with pale white lenticels. The leaf petiole can be 15–30 cm or longer; there are 4–5 pairs of leaflets, thin-leathery, oblong-elliptic to oblong-lanceolate, often asymmetrical on both sides; the petiolules are usually no more than 5 mm long. The inflorescence is large and much branched; the pedicels are short; the sepals are nearly leathery, triangular-ovate; the petals are milky white, lanceolate, about the same length as the sepals, with only the outer surface covered in fine hairs; the filaments are covered with short, stiff hairs. The fruit is nearly spherical, typically yellowish-brown or sometimes grayish-yellow, slightly rough on the outside, or occasionally with small convex bumps. The seed is dark brown, glossy, and entirely enclosed in a fleshy aril. It flowers in spring and summer, and the fruits ripen in summer.
