Wild vine crop territory (8)
I believe the answer is:
province
'territory' is the definition.
(synonyms)
'wild vine crop' is the wordplay.
'wild' indicates an anagram.
'vine'+'crop'='vinecrop'
'vinecrop' is an anagram of 'PROVINCE'.
(Other definitions for province that I've seen before include "Administrative region" , "Territorial division" , "Munster or Leinster, say" , "department?" , "Territory" .)
