Tree with fine wood (6)
I believe the answer is:
walnut
'tree with fine wood' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for walnut that I've seen before include "Decorative variety of wood" , "Valuable furniture wood" , "Hard dark-brown wood used furniture" , "Hard seed with furrowed shell" , "A hardwood" .)
