Cariniana estrellensis is a species of rainforest tree in the family Lecythidaceae. It is native to South America. These trees can grow to extraordinary size. Perhaps the largest rainforest tree ever measured by college trained forester was a C. estrellensis measured by Edmundo Navarro de Andrade which was twenty-three feet thick (twenty-two meters girth) with no buttresses or basal swelling.
