When is a Tree Not a Tree?

When it's a banana.  

I'm working on a new 26 project called 26 Trees.  I am in the "Explore" group which was encouraged to look at trees outside the UK.  When I was in Jakarta, and fell in love with a banana tree, it was disappointing to discover the banana tree isn't technically a tree at all.  Tall as a tree, looks like a tree, everybody calls it a tree - close but still, er, no bananas.  (It is, in fact, a herbaceous plant.)  I pleaded for being able to write about my banana "tree" anyway, and my editor gave me permission.  The result will be unveiled later this year, but in the meantime, have some photos -
