Peach or beech (4)
I believe the answer is:
tree
This clue is a double definition.
'peach' is the first definition.
(thesaurus)
'beech' is the second definition.

(Other definitions for tree that I've seen before include "Beech, for example" , "Plant with trunk (which families have)" , "Diagram representing different relationships" , "Oak, for example" , "Tall perennial plant" .)
