Sterculia urens, commonly known as the Ghost Tree or Gum Karaya, is a medium-sized deciduous tree that can grow up to 15 meters tall. It has a distinctive, smooth, fibrous, and thick greenish-grey bark that peels off in large flakes, giving it a ghostly appearance. The leaves are alternate, simple, and hairy beneath, with three to five palmate lobes. The flowers are yellowish-green and produced in panicles in the axils of the leaves. The fruit is a woody capsule that splits open when ripe to reveal up to six squarish, brown or black seeds.
The tree is native to the Indian subcontinent, including India and Bangladesh, and has been introduced to Myanmar. It grows in deciduous forests, both wet and dry, and is often found on steep, rocky slopes at altitudes between 400 and 800 meters. The tree’s unique appearance and adaptability make it a valuable species in its ecosystem.
