Pine or palm (4)
I believe the answer is:
tree
I believe this clue is a double definition.
'pine' is the first definition.
(thesaurus)
'palm' is the second definition.
(thesaurus)
(Other definitions for tree that I've seen before include "Be up a .... to be in difficulties" , "Woody growth" , "Shakespearean actor" , "plane, say?" , "Plane perhaps" .)
