Tropical fruit tree (5)
I believe the answer is:
guava
'tropical fruit tree' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for guava that I've seen before include "Pear-shaped tropical fruit" , "Fruit from South America" , "Pale orange tropical fruit" , "piece of fruit" , "Tropical tree with yellow fruit" .)
