Ceiba pentandra is a tropical tree of the order Malvales and the family Malvaceae (previously placed in the family Bombacaceae), native to Central America, the Caribbean, and the northern half of South America; some authors also consider it native in western and central Africa. It is widely introduced in other tropical regions including South and Southeast Asia, where it is cultivated.
The tree and the cotton-like fluff obtained from its seed pods are commonly known in English as kapok, a Malay-derived name which originally applied to the related species Bombax ceiba, a native of tropical Asia. In Spanish-speaking countries the tree is commonly known as "ceiba" and in French-speaking countries as fromager. The tree is cultivated for its cottonlike seed fibre, particularly in south-east Asia, and is also known as the Java cotton, Java kapok, silk-cotton or samauma.
