Depending upon climate and soil type the tree may grow to over 100 feet (30 m)[8] in height, but it typically stands 30–40 ft (9–12 m) in height and the crown is round.[3][9] The trunk is 2.5 ft (0.8 m) thick[3] with corky bark.[9] The branches are long and thick, typically drooping.[3] The leaves are oblong and blunt-tipped, usually 4–8 inches (10–20 cm) long and 2 in (5 cm) wide.[3] The leaves are pinnately compounded and alternate.[9] There are 6 to 9 pairs of leaflets per leaf[9] and the upper surface is wavy and a dark, glossy-green.[3] The longan tree produces light-yellow inflorescences at the end of branches.[3] The inflorescence is commonly called a panicle; they can be 4–18 in (10–46 cm) long, and widely branched.[9] The small flowers have 5 to 6 sepals and petals that are brownish-yellow.[9] The flower has a two-lobed pistil and 8 stamen. There are three flower types, distributed throughout the panicle;[3] staminate (functionally male), pistillate (functionally female), and hermaphroditic flowers.[9] Flowering occurs as a progression.[9] The fruit are circular and about 1 in (2.5 cm) wide; they hang in drooping clusters. The peel is tan, thin, and leathery with tiny hairs.[9] The flesh is translucent, and the seed is large and black with a circular white spot at the base.[3][9] This gives the illusion of an eye.[3] The flesh has a musky, sweet taste, which can be compared to the flavor of lychee fruit.[3]
