Exbucklandia
In the forest, where exbucklandia usually grows, the trunk is single, straight, and free of branches for 9 to 18 m. Exbucklandia s are evergreen trees. The leaf blade is simple, and sometimes has three pointed lobes, or rarely, five. It is thickly leathery and its margin is entire. The venation is palmate, with the secondary veins radiating from the apex of the petiole. Each inflorescence has 7 to 16 flowers and is located in the axil of a leaf. The flowers are small and bisexual. The fruit is a 4-valved capsule. Each locule contains five to seven seeds. The upper four or five are sterile and wingless. The lowest one or two are fertile and narrowly winged. Estimates of the number of species range from two to four. They are medium to large trees whose natural range is from eastern India through southern China and southward through the Malay Peninsula. A few have been grown in the southernmost parts of the United States.
