Remove from deciduous tree (4)
I believe the answer is:
oust
'remove' is the definition.
(I've seen this before)
'from deciduous tree' is the wordplay.
'from' indicates the answer is hidden within the clue.
'OUST' is hidden in the letters of 'deciduous tree'.
(Other definitions for oust that I've seen before include "Drive out, eject from office" , "Force out; supplant" , "Remove from a position or office" , "Throw out" , "Expel (from a place)" .)
