The silk floss tree (Ceiba speciosa, formerly Chorisia speciosa), is a species of deciduous tree 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"), samu'ũ (in Guarani) or paineira (in Brazilian Portuguese). In Bolivia, it is called toborochi, meaning "tree of refuge" or "sheltering tree". It belongs to the same family as the baobab and the kapok. Another tree of the same genus, Ceiba chodatii, is often referred to by the same common names.
