I have been unable to find a common name for this tree in English. In Spanish it is called the "Palo Borracho Rosado" which means something like "Drunk Pink Pole". The tree is native to Paraguay and Brazil. I took these pictures in Malaga, Spain quite near to the entrance of the port in a garden that the locals call "Paseo del Parque" (a sign in the park reads "Jardines de Muñoz de Grain"). At any rate this park has a collection of trees and plants that rivals many botanical gardens.A sign at the base of this tree last year indicated that it was Chorisia Speciosa but it has recently been replaced with a new sign that gives the species as Ceiba Pubiflora. The two trees have a lot in common but are not identical. For one the thorns (spikes) on the C. Pubiflora are a lot smaller than those of the Chorisia Speciosa or Chorisia Insignis. From a distance the flowers look very similar also but up close the differences can be easily seen.
