Ceiba speciosa, the floss silk tree (formerly Chorisia speciosa), is a species of deciduous tree that is native to the tropical and subtropical forests of South America. It has several local common names, such as palo borracho (in Spanish literally "drunken stick"), or árbol del puente, samu'ũ (in Guarani), or paineira (in Brazilian Portuguese). In Bolivia, it is called toborochi, meaning "tree of refuge" or "sheltering tree". In the USA it often is called the silk floss tree. It belongs to the same subfamily as the baobab; the species Bombax ceiba; and other kapok trees. Another tree of the same genus, Ceiba chodatii, is often referred to by the same common names.
