Bow wood (3)
I believe the answer is:
yew
'bow wood' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for yew that I've seen before include "Wood for bows" , "'Evergreen tree, reddish-brown wood (3)'" , "Wood for archers" , "Tree associated with graveyards" , "Common churchyard feature" .)
