Conifer leaves (7)
I believe the answer is:
needles
'conifer leaves' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for needles that I've seen before include "Isle of Wight feature - irritates" , "landmark" , "Slender points of a conifer" , "required by dressmakers?" , "Sewers; annoys" .)
