Drought-damaged (4)
I believe the answer is:
sere
'drought-damaged' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sere that I've seen before include "Dried up, withered" , "Dry, withered" , "'Dried-up, shrivelled (4)'" , "Erse (anag.); withered (literary)" .)
