|Kapok planted in Honolulu, Hawai'i|
Ceiba pentandra is a tropical tree of the order Malvales and the family Malvaceae (previously separated in the family Bombacaceae), native to Mexico, Central America and the Caribbean, northern South America, and (as the variety C. pentandra var. guineensis) to tropical west Africa. A somewhat smaller variety is found throughout southern Asia and the East Indies. Kapok is the most used common name for the tree and may also refer to the cotton-like fluff obtained from its seed pods. The tree is cultivated for the seed fibre, particularly in south-east Asia, and is also known as the Java cotton, Java kapok, silk-cotton, samauma, or ceiba.

The tree grows to 240 ft (73 m), as confirmed by climbing and tape drop  with reports of Kapoks up to 252 feet (77 meters)  Trunks can often be up to 3 m (9.8 ft) in diameter above the extensive buttresses. The very largest individuals, however, can be 19 feet (5.8 meters) thick or more above the buttresses.   
The buttress roots can be clearly seen in photographs extending 40 to 50 feet (12 to 15 meters) up the trunk of some specimens  and extending out from the trunk as much as 65 feet (20 meters) and then continuing below ground to a total length of 165 feet (50 meters)  
The trunk and many of the larger branches are often crowded with large simple thorns. These major branches, usually 4 to 6 in number, can be up to 6 feet (1.8 meters) thick   and form a crown of foliage as much as 201 feet (61 meters) in width.  The palmate leaves are composed of 5 to 9 leaflets, each up to 20 cm (7.9 in) long.
The referenced reports make it clear that C. pentandra is among the largest trees in the world.
Kapok fibre is light, very buoyant, resilient, resistant to water, but it is very flammable. The process of harvesting and separating the fibre is labour-intensive and manual. It is difficult to spin, but is used as an alternative to down as filling in mattresses, pillows, upholstery, zafus, and stuffed toys such as teddy bears, and for insulation. It was previously much used in life jackets and similar devices until synthetic materials largely replaced the fibre. The seeds produce an oil that is used locally in soap and can be used as fertilizer.
Ceiba pentandra bark decoction has been used as a diuretic, aphrodisiac, and to treat headache, as well as type II diabetes. It is used as an additive in some versions of the psychedelic drink Ayahuasca.
A vegetable oil can be pressed from kapok seeds. The oil has a yellow colour and a pleasant, mild odour and taste,  resembling cottonseed oil. It becomes rancid quickly when exposed to air. Kapok oil is produced in India, Indonesia and Malaysia. It has an iodine value of 85–100; this makes it a nondrying oil, which means that it does not dry out significantly when exposed to air.  Kapok oil has some potential as a biofuel and in paint preparation.
According to the folklore of Trinidad and Tobago, the Castle of the Devil is a huge kapok growing deep in the forest in which Bazil the demon of death was imprisoned by a carpenter. The carpenter tricked the devil into entering the tree in which he carved seven rooms, one above the other, into the trunk. Folklore claims that Bazil still resides in that tree.
