Oak or beech

I believe the answer is:

tree

I believe this clue is a double definition.

'oak' is the first definition.
(I've seen this before)

'beech' is the second definition.
(thesaurus)

(Other definitions for tree that I've seen before include "famous actor" , "Large woody plant (4)" , "Big plant" , "cross" , "Stand for mugs" .)

I've seen this clue in The New York Times.
