Regularly harvested wheat in this Caribbean location (5)
I believe the answer is:
haiti
'location' is the definition.
(Haiti is an example)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for haiti that I've seen before include "Republic on island" , "West Indian republic" , "Caribbean country, capital Port-au-Prince" , "Western half of Hispaniola" , "W. Indies republic on Hispaniola" .)
