Southern live oak, for example (4)
I believe the answer is:
tree
'southern live oak for example' is the definition.
(southern live oak is a kind of tree)
This is all the clue.
(Other definitions for tree that I've seen before include "Plane or pine, for example?" , "Laurel, perhaps" , "Tall perennial plant" , "eg Rowan" , "Elder, possibly" .)
