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 a host of local common names, such as palo borracho (in Spanish literally "drunken stick"). It belongs to the same family as the baobab and the kapok. Another tree of the Ceiba genus, C. chodatii, often receives the same common names.
