Bundle of corn (5)
I believe the answer is:
sheaf
'bundle of corn' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for sheaf that I've seen before include "Bundle, as of reeds for thatching" , "A bundle, of corn stalks or papers" , "Bundle of several things tied together" , "Bundle of cereal plants" , "set of papers" .)
