Tree in travel magazine (3)
I believe the answer is:
elm
'tree' is the definition.
(I know that elm is a type of tree)
'in travel magazine' is the wordplay.
'in' says the answer is hidden in the clue.
'ELM' is hidden within 'travel magazine'.
(Other definitions for elm that I've seen before include "one has a trunk and leaves" , "Tree of the genus Ulmus" , "Furniture wood" , "Tree for a Cockney tiller" , "Victim of fungus" .)
