Blight-stricken tree (3)
I believe the answer is:
elm
'blight-stricken tree' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for elm that I've seen before include "Large tree" , "one has a trunk and leaves" , "Tall shade tree" , "Species of tree" , "One [TYPE OF TREE]" .)
