Ceiba is a genus of trees in the family Malvaceae, native to tropical and subtropical areas of the Americas (from Mexico and the Caribbean to N Argentina) and tropical West Africa. Some species can grow to 70 m (230 ft) tall or more, with a straight, largely branchless trunk that culminates in a huge, spreading canopy, and buttress roots that can be taller than a grown person. The best-known, and most widely cultivated, species is Kapok, Ceiba pentandra, one of several trees called kapok. Ceiba species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species, including the leaf-miner Bucculatrix ceibae, which feeds exclusively on the genus. Recent botanical opinion incorporates Chorisia within Ceiba and puts the genus as a whole within the family Malvaceae.
