Tree on fire...

My favorite flowery tree...(and it also has those wonderful pods!)...at the entrance to the campus. I'd never seen such a profusion of flowery trees as I've seen here in Thailand.

Tree-pods?/Arbol de chauchas

I'm always amazed at how many trees in this tropical country produce pods...why?
De donde vienen las chauchas?? (del arbol de chauchas, of course :) )
