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