Ceiba speciosa
Kingdom: Plantae (unranked): Angiosperms (unranked): Eudicots (unranked): Rosids Order: Malvales Family: Malvaceae Genus: Ceiba Species: C. speciosa Binomial name Ceiba speciosa 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 same genus, Ceiba chodatii, is often referred to by the same common names.
The natural habitat of the silk floss tree is the north-east of Argentina, east of Bolivia, Paraguay, Uruguay and southern Brazil. It is resistant to drought and moderate cold. It grows fast in spurts when water is abundant, and sometimes reaches more than 25 metres (82 ft) in height. Its trunk is bottle-shaped, generally bulging in its lower third, measuring up to 2 metres (7 ft) in girth. The trunk is also studded with thick, sharp conical prickles which deter wild animals from climbing the trees. In younger trees, the trunk is green due to its high chlorophyll content, which makes it capable of performing photosynthesis when leaves are absent; with age it turns to gray.
